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
Attached Figure / Diagram
A
13.3N
B
20.0N
C
40.0N
D
80.0N
Verified Correct Answer: D.
Physical Principles & Numerical Solution
With P1 and P2 as shown (make a V.R of 2), the weight W = 40N * 2 = 80N
