PRACTICE EXERCISE 2: TRUE or FALSE
Directions: Write T if the statement is correct and F if the statement is incorrect. Write your answer on the space provided before each number.
1. A fixed pulley has the axle fixed on a surface and therefore does not move. Its fulcrum is at the center of the axle with load and effort on either side.
2. A block-and-tackle pulley moves along the rope or wire. The fulcrum is at the edge of the wheel with the load at the middle of the axle and the effort at one end of the rope.
3. A block-and-tackle (compound) pulley is made up of a combination of two or more fixed and movable pulleys.
4. Movable pulley increases the magnitude of the force but decreases its distance.
