A tractor A is used to hoist the heavy body B with a pulley system as shown in figure. If the tractor has a velocity 25 km/hr towards right, find velocity (in km/hr) of the body B.

Answer:

Solution:

Virtual work for the massless string-pulley system: $\sum F \cdot v = 0 \Rightarrow (5 T) v_{B} = T v_{A} cos 3 7^{\circ}$ .

$v_{B} = \frac{25 \times ( 4/5 )}{5} = 4 km/hr$ . Answer: 4.
