Question

Cathy, a 460-N actress playing Peter Pan, is hoisted above the stage in order to "fly" by a stagehand pulling with a force of 60. N on a rope wrapped around a pulley system. What is the actual mechanical advantage of the pulley system?

Answer 1

Answer:7.67

Step-by-step explanation:

Given

Weight of Cathy
`W_1=460\ N`

Force exerted by rope
`F=60\ N`

Mechanical advantage is the ratio of load by Pulling effort

`M.A.=(Load)/(Pulling\ effort)`

`M.A.=(460)/(60)`

`M.A.=7.67\ N`
