Answer:
Mechanical advantage of pulleys = 3.47 (Approx)
Explanation:
Given:
Manual force = 1,549 N
Pulleys force = 446 N
Find:
Mechanical advantage of pulleys
Computation:
Mechanical advantage of pulleys = Manual force / Pulleys force
Mechanical advantage of pulleys = 1,549 / 446
Mechanical advantage of pulleys = 3.4730
Mechanical advantage of pulleys = 3.47 (Approx)
