1. What is the direction of the friction force on the block B?
2. Draw clear diagrams to show the forces on each of A, B and C.
3. By considering the equilibrium of A and C, calculate the tensions in the strings
when there is no slipping.
4. Calculate the magnitude of the friction when there is no slipping.
Now suppose that there
insufficient friction to stop the block from slipping.
