Suspension holding cylinder pulls up on cylinder with force

Reference no: EM13649036

A 0.70-kg disk with a rotational inertia given by MR2/2 is free torotate on a fixed horizontal axis suspended from the ceiling. A string is wrapped around the disk and a 2.0-kg mass hangs from the free end. If the string does not slip, then as the mass falls and the cylinder rotates, the suspension holding the cylinder pulls up on the cylinder with aforce of:

A. 6.9N
B. 9.8N
C. 16N
D. 26N
E. 29N
