Sample Question:

A pulley system has three pulleys arranged vertically. A rope runs over the pulleys, and one end of the rope is attached to a weight of 150 pounds. If each pulley reduces the force required to lift the weight by one-third, what is the force needed to lift the weight using the pulley system?

A) 50 pounds

B) 100 pounds

C) 150 pounds

D) 200 pounds


Since each pulley reduces the force required by one-third, and there are three pulleys, the force required would be reduced by one-third three times:

150 / 3 = 50 50 / 3 = 50/3 50/3 / 3 = 50/9

The force required is one-ninth of the original 150 pounds, which is:

150 / 9 = 50/3 * 2 = 100/3 ≈ 33.33 pounds

However, this option is not provided in the answer choices. The closest option is:

A) 50 pounds
