Answer:
(a) 145 N
(B) 40 N
(c) 10 ropes
Explanation:
Mechanical advantage, where and are input and output force respectively
Since MA is given as 10 and input force is 1450 N
Therefore, the mover must use a force of 145 N
(b)
Since also and the is given as 4 m then
(c)
Literally, we need 10 rope segments to support the piano since we utilize the mechanical advantage
