Question

what is the mechanical advantage of a pulley that changes only the direction of the load, not the effort force
0.5
1.0
1.5
2.0

Explanation:

A fixed pulley only changes the direction of the force. The mechanical advantage (MA) is calculated as \(MA=\frac{F_{load}}{F_{effort}}\). For a fixed pulley, \(F_{load} = F_{effort}\), so \(MA = 1.0\).

Answer:

B. 1.0
