The figure above represents a frictionless pulley system in which a weight W is in equilibrium with a weight of 40N. Find the value of W.

Answer Details

In a frictionless pulley system, the tension in the string is constant throughout. Since the weight of 40N is being balanced by weight W, the tension in the string must be equal to 40N. Therefore, we have: Tension = 40N Also, we know that the weight W is balanced by the tension in the string. Therefore: W = Tension = 40N So the value of W is 40N. Answer: 40.0N
