Question

Which one of the pulley systems below has the best force advantage?Select one:a. Pulley Ib. Pulley IIc. Pulley IIId. The force advantage is the same.

Answer 1

a. Pulley I

Step-by-step explanation

A pulley system is a collection of one or more wheels which are used with a. rope or chain to make it easier to lift things, The main advantage in the use of pulleys is that the effort becomes less as compared to the normal lifting of the weights

the ideal mechanical advantage is equal to the number of rope segments pulling up on the object. The more rope segments that are helping to do the lifting work, the less force that is needed for the job.

so

Step 1

let's check the number of pulleys on each system

so, the firs system has the more rope segements pulling up (4)

therefore, the answer is

a. Pulley I
