The power steering in an automobile has mechanical advantage of roughly 75. If the ramp is 4.6 m long and friction between the ramp and crate can be ignored, what is the mechanical advantage of the ramp? Q Ra I C FĨ 7. The crate, which must be lifted 1.4 m from the street to the bed of the truck, is pushed along the length of the ramp. A mover uses a ramp to load a crate of nails onto a truck. What is the distance of effort for a claw hammer if the distance of resistance is 2.0 cm and the mechanical advantage is 5.5? Q Ra I C Fħ 6. Suppose you need to remove a nail from a board by using a claw hammer. What is the mechanical advantage of the shovel? Q Ra I C FĦ 5. The shovel applies a force of 600 N to the weed. To pull a weed out of a garden, you can apply a force of 50 N to the shovel. If an engine has a weight of 1,800 N, how much force will be required to lift the engine with a pulley system that has a mechanical advantage of 6? Q Ra I C Fĥ 4. What is the mechanical advantage of the pulley? Q Ra I C FĤ 3. The rope applies a force of 700 N to the block. To lift a block on a movable pulley, you can apply a force of 50 N to a rope.
