Question

station 4
simple machines
which pulley would require the least amount of force to lift the weight?
r. pulley a
s. pulley b
t. pulley c
v. they all require the same amount of force.

Explanation:

Step1: Understand pulley - force relationship

The more ropes supporting the weight in a pulley system, the less force is required to lift it.

Step2: Analyze each pulley

Without seeing the actual pulley - systems A, B, and C, assume a basic principle: if one pulley has more ropes attached to the weight - lifting part compared to others, it will require less force. But if they are single fixed or single movable pulleys in a basic comparison, a single movable pulley (where the pulley itself moves with the load) requires less force than a single fixed pulley (where the pulley is fixed in place). If we assume pulley C is a single movable pulley and A and B are single fixed pulleys, pulley C will require the least force.

Answer:

T. Pulley C
