Question
Q3. The double pulley shown in Fig Q3 has a mass of 14 kg and a centroidal radius of gyration
of 165 mm. A and B are attached to cords that are wrapped around the pulley. µk = 0.25 between
B and the surface. A friction moment exists in the axle of the pulley of 0.8 Nm.
Knowing the system is released from rest, at the position shown,
Using hand Calculations to determine,
a) The velocity of A as it strikes the ground
b) The total distance covered by B before it comes to rest.
Using MATLAB to plot the variation of the velocity with the work done by the system.
