Lifting the weight without a pulley, requires a force of 400 N over distance of 4 m how do these values change when the pulley is applied?
When a pulley is applied, the force required to lift the weight decreases and the distance over which the force is applied increases. This is because the pulley system allows for the force to be distributed among multiple ropes and pulleys, reducing the amount of force required to lift the weight.
In this case, if the force required to lift the weight is 400 N over a distance of 4 m without a pulley, when a pulley is applied, the force required may decrease to, for example, 200 N and the distance over which the force is applied may increase to 8 m. This means that with the pulley system, the same weight can be lifted with less force and over a longer distance.
