A single cable supports a solid circular disk a and block b

Question

I . The 2-ft diameter. 50-lb circular disk has a Radius of Gyration of Ko=0.75 ft. Determine the Moment of Inertia of the disk in ft²-slugs about

a) the Z axis

b) the X axis

c) line a-a

d) Point A, rotating only with line b-b in the X-Y plane

e) Line BB in a plane perpendicular to the X-Y plane

2. A single cable supports a solid circular disk A and block B. The masses are 40kg and 25kg respectively. There is no slipping between the disk and cable. After the block is released from rest, determine:

a) The angular acceleration in. rad/s2 of the disk

b) The acceleration in m/s2 of the weight

c) The tension in Newtons of the cable attached to weight B

d) The tension in Newtons of the cable attached to Point C

e) Determine the relative acceleration aB/A
