Question

Given:

Find: 

A) Write down an expression for the magnitude of the torque on the cylindrical shell, about the axis of rotation of the cylindrical shell, in terms of the tension T in the rope.  Then write down an expression for the net force on the block.

B) Write down an expression that relates the magnitude   of the angular acceleration of the cylindrical shell to the magnitude a of the linear acceleration of the block.

C) Using the results in (a) and (b), calculate values for the tension  T in the rope, and for the magnitudes of the angular acceleration of the cylindrical shell and the linear acceleration a of the block.

I'd appreciate any help, please show work to help me understand the question - thanks! Lifesaver to the person to assists me.

Explanation / Answer

10*9.81-T= 10*a

T= 15*a

a=*r

after solving, a=3.92

= 15.68

torque= I*

I= moment of inertia of hollow cylindrycal cell
