Answer :
F(0) = -5 < 0
F(1) = e - 1 > 0
since the functions : f(0) and f(1) have opposite signs then there is a 'c' whereby F(c) = 0 ( intermediate value theorem fulfilled )
Hence there is a root in the given equation : \(e^x = 6 - 5x\)
Explanation:
using Intermediate value Theorem
If F(x) is continuous and f(a) and f(b) have opposite signs then there will be a'c'E (a,b) whereby F(c) = 0
given equation : \(e^x = 6 - 5x\) on (0,1)
and F(x) = \(e^x - 6 + 5x = 0\)
This shows that the F(x) is continuous on (0,1)
F(0) = \(e^0 - 6 + 5(0)\) = -5 which is < 0
F(1) = \(e^1 -6 + 5(1)\) = e -1 > 0 and e = 2.7182
since the functions : f(0) and f(1) have opposite signs then there is a 'c' whereby F(c) = 0 ( intermediate value theorem fulfilled )

The steel shaft has a diameter of 40 mm and is fixed at its ends A and B . If it is subjected to the couple determine the maximum shear stress in regions AC and CB of the shaft. G st = 75 GPa.
Q6/
Answers
Answer:
See explanation.
Explanation:
Since no figure was given I solved a problem that was similar to the one you described that I worked in my mechanics of materials class. The method should be very similar for your figure. See attached image for my work.
If it is subjected to the couple determine the maximum shear stress in regions AC and CB of the shaft. G st = 75 GPa. Than the answer will be 52Mpa.
What we need to perform?We need to perform a two step process to obtain the maximum shear stress on the shaft. For the solid shaft,
P=2×pi×N×T/60 or T=60×p/2×pi×N
Where P=power transmitted by the shaft=50×10³W
N=rotation speed of the shaft in rpm=730rpm
Pi=3.142
T is the twisting moment
By substituting the values for pi, N and P, we get
T=654Nm or 654×10³Nmm
Also, T=pi×rho×d³/16 or rho=16×T/pi×d³
Where rho=maximum shear stress
T = twisting moment=654×10³Nmm
d= diameter of shaft= 40mm
By substituting T, pi and d
Rho=52Mpa
b. For a hollow shaft, the value for rho is unknown
T=pi×rho(do⁴-di⁴/do)/16
Rho=T×16×do/pi×(do⁴-di⁴)
Where
T= twisting moment=654×10³Nmm gotten above
do=outside shaft diawter=40mm
di= inside shaft diameter =30mm
Pi=3.142
Substituting values for pi, do, di and T.
Rho=76Mpa
Therefore, If it is subjected to the couple determine the maximum shear stress in regions AC and CB of the shaft. G st = 75 GPa. Than the answer will be 52Mpa.

Upon arrival, the parts are sent to Machine 1 and processed. The processing-time distribution is TRIA(4. 5, 9. 3, 11) minutes. The parts are then processed at Machine 2 with a processing-time distribution as TRIA(16. 4, 19. 1, 28) minutes. The parts from Machine 2 are directed back to Machine 1 to be processed a second time (same processing-time distribution as the first visit but an independent draw from it). The completed parts then exit the system. Run the simulation for a single replication of 20,000 minutes to observe the average number in the machine queues and the average part cycle time
Answers
To run the simulation, we can use a discrete-event simulation approach. We start by setting up the initial state of the system, including the arrival schedule of the parts, the state of the machines, and the statistics we want to track.
Then, we can simulate the arrival and processing of each part, keeping track of the time stamps and the state of the machines. We update the statistics at each event, such as when a part arrives, starts processing, finishes processing, and leaves the system.
After running the simulation for 20,000 minutes, we can calculate the average number in the machine queues and the average part cycle time from the collected statistics. These metrics provide insight into the performance of the system and can be used to identify potential bottlenecks or areas for improvement.

if the wall shear stress in a horizontal 50 m run of 400 mm diameter pipeline is 7.0 pa, what is the associated pressure drop in units of kpa? assume fully developed flow.
Answers
The pressure drop in a 50 m run of a 400 mm diameter pipeline with a wall shear stress of 7.0 Pa is 8.75 kPa.
To calculate the pressure drop, first, we need to find the friction factor (f) for fully developed flow.
Using the Darcy-Weisbach equation, we can relate wall shear stress (τ) to friction factor as follows:
τ = (1/2)ρv²f, where ρ is fluid density and v is fluid velocity.
Next, we can use the pressure drop equation: ΔP = f(L/D)(ρv²/2), where L is the pipeline length and D is the pipeline diameter.
Rearrange the equation for ΔP and substitute the known values, ΔP = (τ/ρ)(2L/D).
For simplicity, we'll assume a fluid density (ρ) of 1000 kg/m³.
Convert the diameter to meters (0.4 m) and calculate,
ΔP: (7.0 Pa / 1000 kg/m³)(2 * 50 m / 0.4 m) = 8.75 kPa.

Answers
The total mass of water in the tank decreases as the pressure increases from 0.1 MPa to 1 MPa.
As the pressure increases, the water vapor in the piston-cylinder device undergoes compression, causing a decrease in its volume. This decrease in volume leads to a decrease in the amount of water vapor present in the system. Since the water and water vapor are in equilibrium, a decrease in the amount of water vapor also results in a decrease in the amount of liquid water.
At lower pressures, there is a larger amount of water vapor in the system, and as the pressure increases, the vapor condenses into liquid water. Therefore, as the pressure increases from 0.1 MPa to 1 MPa, the total mass of water in the tank decreases.

A 4 stroke over-square single cylinder engine with an over square ratio of 1.1,the displacement volume of the engine is 245cc .The clearance volume is 27.2cc the bore of this engine is ?
Answers
Answer:
10.007
Explanation:
Assuming we have to find out the compression ratio of the engine
Given information
Cubic capacity of the engine, V = 245 cc
Clearance volume, V_c = 27.2 cc
over square-ratio = 1.1
thus,
D/L = 1.1
where,
D is the bore
L is the stroke
Now,
Volume of the engine V =\(\frac{\pi}{4} D^2L\)
plugging values we get
245 = \(\frac{\pi}{4} D^3/1.1\)
Solving we get D =7 cm
therefore, L= 7/1.1 =6.36 cm
Now,
the compression ratio is given as:
r =(V+V_c)/V_c
on substituting the values, we get
r = (245+27.2)/27.2 =10.007
Hence, Compression ratio = 10.007

1. To determine the value of k, the cost coefficient in the Taguchi quality loss function, we need to divide the cost of handling complaints ($40.00 per chip) by the square of the expected customer complaint threshold (0.0001 mm). k = ($40.00) / (0.0001 mm)^2 = $4,000,000.
2. According to the Taguchi quality loss function, the tolerance before an adjustment is made at the factory should be set at the point where the loss due to deviation in quality is minimized. Since the cost of making adjustments at the factory is $2.30, including labor and testing, we can calculate the tolerance using the formula: Tolerance = √(k * Cost of adjustment) = √($4,000,000 * $2.30) = √$9,200,000 ≈ 0.0004 mm.
3. Based on the above calculation, the specification limits for the production of the product in question would be an upper limit of 0.9 mm + 0.0004 mm = 0.9004 mm and a lower limit of 0.9 mm - 0.0004 mm = 0.8996 mm. These limits ensure that the distance between two adjacent pins falls within the desired tolerance of 0.9 mm ± 0.0004 mm, minimizing the risk of interference while maintaining cost-effectiveness for adjustments.
