Unformatted text preview: the drum and ground. The system is wrapped around the inner
of the drum and is connected to particle A having a mass of m. The cable is also wrapped over an
spring unstretched.
V56 ideal pulley. A spring of stiﬀness K is attached between G of the drum and ground. The system is
released from rest with the spring unstretched. Find: Determine the speed of A after it has dropped 2 meters. Find: Determine the speed of A after it has dropped through a distance of d. pulley has
negligible mass M R K
r G
no slip m A Use the following parameters in your analysis: M = 30kg , m = 10kg , R = 0.5m, r = 0.25m,
kG = 0.3m, K = 100N/m and d = 2m. the center of the disk A is moving to the right with a speed of vA1 = 5 m/sec
and has a counterclockwise rotation rate of !1 = 8 rad/sec, as shown in Figure
1 below. In Figure 2 below is shown the instant at which the disk ceases to
slip as it continues to move on the horizontal surface.

Find: For this problem:
a) Determine the speed of A, vA2, at the instant in Figure 2 when the disk
ceases to slip on the h outer radius of R
Given: A homogeneous disk (with mass M andorizontal surface. ) is placed on a rough surface.
b) Determine the e the disk A is movi...
