False. Driving in a zigzag motion, even in an empty parking lot, is not safe and should be avoided. While it may seem like a harmless way to have fun or practice driving skills, it can be dangerous for several reasons.
For one, sudden changes in direction can cause the driver to lose control of the vehicle, particularly at higher speeds. Additionally, it can be difficult for other drivers or pedestrians to anticipate where the zigzagging vehicle will go next, putting them at risk of collision or injury. It is important to always drive in a safe and responsible manner, following traffic laws and avoiding risky maneuvers that can endanger oneself or others.
In addition to the safety concerns, driving in a zigzag motion is also not an efficient use of a vehicle's fuel. Accelerating and braking abruptly uses more fuel than driving at a steady pace, and constantly changing direction can increase the amount of fuel used. This not only wastes money, but also contributes to unnecessary air pollution and carbon emissions. Therefore, it is important to drive in a straight line whenever possible and to avoid unnecessary maneuvers that can waste fuel and harm the environment.

he beam ab is pin supported at a and supported by a cable bc. a separate cable cg is used to hold up the frame. if ab weighs 120 lb / ft and the column fc has a weight of 180 lb / ft, determine the resultant internal loadings acting on cross sections located at points d and e.
At point D, the resultant internal loading is a vertical reaction of 120 lb/ft and an upward force in the cable BC of 120 lb/ft. At point E, the resultant internal loading is a downward force of 120 lb/ft (from the weight of AB), a downward force of 180 lb/ft (from the weight of FC), and an upward force in the cable CG of 300 lb/ft.
The beam AB is pin-supported at point A and supported by a cable BC. Additionally, a separate cable CG is used to hold up the frame. We need to determine the resultant internal loadings acting on cross sections located at points D and E.
To find the resultant internal loadings, we need to consider the weight of the beam AB and the column FC. The weight of AB is given as 120 lb/ft, and the weight of FC is given as 180 lb/ft.
To determine the resultant internal loadings at points D and E, we need to consider the equilibrium of forces. At point D, we have the weight of AB acting downwards, while the cable BC is providing an upward force. At point E, we have the weight of AB acting downwards, the weight of FC acting downwards, and the cable CG providing an upward force.
Let's start with point D. Since the beam is pin-supported at point A, we know that the vertical reaction at A must be equal to the weight of AB. Therefore, the vertical reaction at A is 120 lb/ft.
Next, let's consider the cable BC. The cable BC is providing an upward force at point D to balance the weight of AB. Therefore, the upward force in the cable BC at point D is also 120 lb/ft.
Moving on to point E, we have the weight of AB acting downwards, which is 120 lb/ft. Additionally, we have the weight of FC acting downwards, which is 180 lb/ft. Therefore, the total downward force at point E is 120 lb/ft + 180 lb/ft = 300 lb/ft.
To balance the downward forces at point E, the cable CG must provide an upward force of 300 lb/ft.
The resultant internal loadings acting on the cross sections located at points D and E are as follows:
- At point D: Vertical reaction of 120 lb/ft and upward force in the cable BC of 120 lb/ft.
- At point E: Downward force of 120 lb/ft (from the weight of AB), downward force of 180 lb/ft (from the weight of FC), and upward force in the cable CG of 300 lb/ft.

1000N. Angle of inclined plane = 450
To find the tension in the string and the acceleration of the block, we can use the equations of motion for the system.
Assuming the mass of the block M1 is 1500N and the mass of the block M2 is 1000N, the equation of motion for the system is given by:
T - μMgcos(θ) = M1a + M2a
Where T is the tension in the string, μ is the coefficient of friction between the block M1 and the inclined plane, Mg is the weight of the blocks, θ is the angle of the inclined plane, and a is the acceleration of the blocks.
Substituting the given values, we get:
T - 0.2(1500 + 1000)9.81cos(45°) = 1500a + 1000a
Simplifying, we get:
T = 6715N - 3000a
Solving for a, we get:
a = (6715 - T)/3000
Therefore, the acceleration of the block is given by (6715 - T)/3000, where T is the tension in the string.
