5. Exercise 10.21
21. Find the net torque on the wheel in Figure about the axle through O, taking a = 10.0 cm and b = 25.0 cm.

6. Exercise 10.23

7. Exercise 10.27
27. A uniform beam of mass mb and length ℓ supports blocks with masses m1 and m2 at two positions as shown in Figure. The beam rests on two knife edges. For what value of x will the beam be balanced at P such that the normal force at O is zero?

8. Exercise 10.32
32. A crane of mass kg supports a load of kg as shown in Figure. The crane is pivoted with a frictionless pin at A and rests against a smooth support at B. Find the reaction forces at A and B.

9. Exercise 10.32
37. Two blocks, as shown in Figure, are connected by a string of negligible mass passing over a pulley of radius m and moment of inertia I. The block on the frictionless incline is moving up with a constant acceleration of 2.00 m/s2. (a) Determine T1 and T2, the tensions in the two parts of the string. (b) Find the moment of inertia of the pulley.
