Per NCERT, what is the primary BENEFIT of a fixed pulley if it doesn't reduce the effort force?
AIt makes the load smaller
BIt changes the DIRECTION of the effort — making it easier to pull downward (using body weight) than to lift directly upward
CIt creates extra energy
DIt makes the rope stronger
Answer & Solution
Correct answer: B. It changes the DIRECTION of the effort — making it easier to pull downward (using body weight) than to lift directly upward
Per NCERT §7.6.1, a fixed pulley provides directional convenience — pulling down is easier than lifting up. The other options misstate.
