1. The box shown in Fig. 10.24 being pulled up an inclined plane using the indicated pulley system (called a block and tackle) weighs 9790 N. If the inclined plane is 6.00 m long and the height of the platform is 2.00 m, find the mechanical advantage of this compound machine.

2. What effort force must be exerted to move the box to the platform in Problem 1?
3. Find the mechanical advantage of the compound machine shown in Fig. 10.25. The radius of the crank is 1.00 ft and the radius of the axle is 0.500 ft.

4. If an effort of 300 lb is exerted, what weight can be moved up the inclined plane using the compound machine in Problem 3?
5. What effort is required to move a load of 1.50 tons up the inclined plane using the compound machine in Problem 3? (1 ton = 2000lb)
