Answers
Answer:
a. If each marble is different, there are 3 jars and 15 marbles, so we need to calculate 3^15 = 14,348,907 possible ways.
b. If each marble is the same, we can use stars and bars to count the number of ways to distribute the marbles among the jars. We need to divide 15 marbles among 3 jars, so we can place 2 dividers (representing the boundaries between the jars) among 14 objects (15 marbles minus 1), and there are C(14,2) = 91 ways to do this.
c. If each marble is the same and each jar must have at least two marbles, we can first distribute 6 marbles among the jars (using the method from part b, with 2 stars and 2 bars), and then distribute the remaining 9 marbles among the jars (again using the same method, but with 1 star and 2 bars). This gives C(6+3-1,2) * C(9+3-1,2) = C(8,2) * C(11,2) = 28 * 55 = 1,540 possible ways.
d. If each marble is the same but each jar can have at most 6 marbles, we can use generating functions to count the number of ways to distribute the marbles. The generating function for each jar is (1 + x + x^2 + ... + x^6), and the generating function for all three jars is (1 + x + x^2 + ... + x^6)^3. The desired coefficient of the x^15 term can be found using the multinomial coefficient C(15+3-1, 3-1, 3-1, 3-1) = C(17,2,2,2) = 15,015. Therefore, there are 15,015 possible ways.
e. If you have 10 identical red marbles and 5 identical blue marbles, we can again use stars and bars to distribute the marbles among the jars. We need to distribute 10 red marbles and 5 blue marbles among 3 jars, so we can place 2 dividers among 14 objects (10 red marbles, 5 blue marbles, and 2 dividers), which gives C(14,2) = 91 possible ways.

Tidal turbines convert the energy of a flowing tide to generate electricity. Early designs of these machines commonly had their rotor attached to a supporting tower mounted on the seabed – see for example Figure QC2.1. A representation of a tide-driven flow of water past a tidal turbine is sketched in Figure QC2.2. An expansion of the flow from d1 to d2 is imagined to occur over the rotor, with half of the expansion (in area) happening upstream of the rotor, and half downstream.
(a) Explain why the active part of the inflow (the streamtube shown in Figure
QC2.2) expands its cross-section as it passes the turbine. (2)
Analysis for the analogous situation of a wind turbine with uniform inflow, attributed to Albert Betz and others in the 1920s, demonstrated that for optimum efficiency of energy extraction from the inflow, the far upstream flow speed should be reduced by the turbine such that the far downstream speed is 1/3rd of the far upstream speed.
(b) Suggest three reasons why this theoretical maximum efficiency will in general
not be achieved in a practical tidal turbine deployment. (3)
(c) The Alstom 1.4 MW OceadeTM turbine has a rotor diameter of 18 m. The
supporting tower has a height of 15 m and a diameter of 3 m. In a 3 ms-1 tidal
flow, estimate the total fluid loading experienced by the whole machine. State
and justify the assumptions that you make in arriving at this estimate. (12)
(d) How would you expect to use these estimates of forces when designing the
turbine and tower structure?
Answers
(a) The active part of the inflow expands its cross-section as it passes the tidal turbine due to conservation of mass and energy.
(b) Several reasons contribute to the theoretical maximum efficiency not being achieved in practical tidal turbine deployments, including turbulence, non-uniform flow, and mechanical losses.
(c) Estimating the total fluid loading on the Alstom 1.4 MW OceadeTM turbine requires considering the flow velocity, rotor and tower dimensions, and making assumptions about the flow characteristics and structural properties.
(d) The estimates of forces obtained from the fluid loading calculations are essential for designing the turbine and tower structure by ensuring that they can withstand the anticipated loads and stresses.
(a) The active part of the inflow expands its cross-section as it passes the tidal turbine due to the principle of conservation of mass and energy. As the tidal flow encounters the turbine rotor, some of the kinetic energy of the flow is converted into mechanical energy to drive the turbine. To satisfy the conservation of mass, the cross-sectional area of the flow must increase to compensate for the reduction in flow velocity caused by energy extraction.
(b) Achieving the theoretical maximum efficiency in practical tidal turbine deployments is challenging due to several reasons. First, tidal flows are often characterized by turbulence, which disrupts the uniformity of the flow and reduces overall efficiency. Second, tidal flow itself is not uniformly distributed, and the flow characteristics vary with tidal cycles, further impacting efficiency. Lastly, mechanical losses in the turbine's components, such as friction and resistance, reduce the efficiency of energy conversion.
(c) Estimating the total fluid loading on the Alstom 1.4 MW OceadeTM turbine involves considering the flow velocity, rotor diameter, and tower dimensions. Assuming a tidal flow velocity of 3 m/s, the fluid loading can be estimated by considering the momentum change and forces acting on the rotor and tower surfaces. Assumptions may include a simplified flow model, neglecting factors such as turbulence and non-uniform flow, and assuming a stationary tower. These assumptions simplify the calculation while providing a reasonable estimate of the fluid loading.
(d) The estimates of forces obtained from the fluid loading calculations are crucial for designing the turbine and tower structure. These estimates help engineers determine the required structural strength, material selection, and design considerations to ensure that the turbine and tower can withstand the anticipated fluid forces and mechanical stresses. By considering the estimated forces, designers can optimize the structural integrity, stability, and reliability of the turbine and tower, ensuring safe and efficient operation in tidal environments.

p6.51 a stepped shaft with a major diameter d = 100mm. and a minor diameter d = 1.25 in. is subjected to a torque of 1,200 lb • in. If the maximum shear stress must not exceed 4,000 psi, determine the minimum radius r that may be used for a fillet at the junction of the two shaft segments. The fillet radius must be chosen as a multiple of 0.05 in.
Answers
the minimum radius r that may be used for a fillet at the junction of the two shaft segments, we can use the formula for maximum shear stress:
τ_max = T*r / (J*C)
Where T is the torque applied (1,200 lb•in), r is the radius of the fillet, J is the polar moment of inertia of the stepped shaft, and C is the distance from the center of the shaft to the outermost fiber.
To calculate J and C, we need to know the diameters of the two shaft segments. We're given that the major diameter (d) is 100mm, and the minor diameter is 1.25 in. Converting the minor diameter to mm, we get:
d_min = 1.25 in * 25.4 mm/in = 31.75 mm
The distance from the center of the shaft to the outermost fiber is simply half of the difference between the major and minor diameters:
C = (100 mm - 31.75 mm) / 2 = 34.625 mm
To calculate the polar moment of inertia J, we need to consider the stepped shaft as two separate cylinders with radii of 50 mm and 15.875 mm. The polar moment of inertia of a solid cylinder is:
J_cyl = π/2 * r^4
So we can calculate J for each cylinder and add them together:
J = J1 + J2
= π/2 * (50 mm)^4 + π/2 * (15.875 mm)^4
= 2.18e8 mm^4
Now we can solve for the minimum fillet radius:
τ_max = 4,000 psi = 4,000 lb/in^2
r = (T / (τ_max * J * C))^1/3
= (1,200 lb•in / (4,000 lb/in^2 * 2.18e8 mm^4 * 34.625 mm))^1/3
≈ 2.56 mm
Since the fillet radius must be chosen as a multiple of 0.05 in, we convert the minimum radius to inches and round up to the nearest multiple of 0.05 in:
r_min = 2.56 mm / 25.4 mm/in = 0.1008 in
r_min_rounded = 0.15 in
Therefore, the minimum fillet radius that may be used at the junction of the two shaft segments is 0.15 inches.

Answers
To calculate the location of the shear center O for the given cross-section, we need to perform two steps: first, calculate the area moment of inertia for the shape about the horizontal centroidal axis, and second, determine the shear center based on the geometry.
Part 1: Calculate the area moment of inertia (I) for the shape about the horizontal centroidal axis:
For a thin-walled shape, the area moment of inertia about the horizontal centroidal axis can be calculated using the parallel axis theorem by considering the individual components of the cross-section.
The given cross-section consists of two rectangular components. The area moment of inertia for a rectangular component about its own centroidal axis is given by the formula:
I_rect = (1/12) * b * h^3
where b is the base (width) and h is the height of the rectangle.

Answers
Answer:
El tiempo que tarda la barca en llegar a la orilla es 40 s.
Explanation:
Debido a que el río se mueve en dirección perpendicular a la barca, ésta se va a mover de manera diagonal, cuya velocidad (\(v_{b_{d}}\)) viene dada por:
\(|v_{b_{d}}| = \sqrt{v_{r}^{2} + v_{b}^{2}} = \sqrt{(4)^{2} + (3)^{2}} = 5 m/s\)
Por lo tanto, el módulo del vector velocidad diagonal es 5 m/s, y su dirección es:
\(tan(\alpha) = \frac{v_{r}}{v_{b}} = \frac{4}{3}\)
Entonces, α es:
\( \alpha = arctan(\frac{4}{3}) = 53.13 ^{\circ} \)
Ahora, debemos encontrar la distancia de la longitud diagonal que recorre la barca:
\( cos(\alpha) = \frac{a}{d_{d}} \)
\( d_{d} = \frac{a}{cos(\alpha)} = \frac{120 m}{cos(53.13)} = 200.0 m \)
Finalmente, el tiempo que le tomaría a la barca recorrer 200 m sería:
\(v_{b_{d}} = \frac{d_{d}}{t}\)
\( t = \frac{200 m}{5 m/s} = 40 s \)
Por lo tanto, el tiempo que tarda la barca en llegar a la orilla es 40 s.

The denity of a certain type of jet fuel i 775 kg/m3. Determine it pecific gravity and pecific weight
Answers
The correct answer is Specific weight: w = [weight ÷ volume] = [9N ÷ 0.001m³] = 9000N/m³Density: w = [ × g] Where, g = acceleration due to gravity = 9.81m/sec². Specific gravity: G = [density of liquid ÷ density of water] As you know, The density of water = 1000kg/m³.
The density of a substance is divided by the density of water at 4 degrees Celsius to determine its specific gravity. The density of the substance and the density of the water must be represented in the same units for the calculation.distinguishes While specific weight has dimensions, specific gravity is a dimensionless number. The gravitational field has no effect on a material's specific gravity, but it does have an effect on a material's specific weight. A substance's "Specific Gravity" is determined by dividing its mass by the mass of an equivalent volume of water at the same pressure and temperature.
