Question

Can tutor explain step by step and also the explanation such as like why use that formula and why is it this cannot. 

below is the questions need to answer by using the diagram 

1)Calculate the velocity of the arm, observed by a stationary person on the ground.

2)Draw the FBD of the combined body (crane body, arm and load).

3)Is the combined body stable? Why?

4)Calculate the moment of the following, about wheel A,
i) combined crane body
ii) load mass

5)Which combined body’s component(s) will not fail? Why? (Hint: The crane was initially in equilibrium.)

6)What are the various limits (maximum or minimum) for the combined body to be stable? Explain why.
