Answer:
Given:
A tractor A is used to hoist the body B with the pulley arrangement shown in fig.
To find:
If A has a forward velocity VĄ, find the velocity of the body B.
Solution:
From given, we have,
The distance between the ground and the pulley, d
The distance between the tractor A and body B, x
The velocity of tractor A, Va
Therefore, the velocity of body B is given by,
Vb = (x × Va)/[2√(d² + x²)]
