Question

A block and tackle system has 5 pulleys. If an effort of 100 N is needed in upward direction to raise a load, what is the mechanical advantage of the system?​

Answer 1

Given:

Pulleys = 5

Effort = 1000N

Load = 4500N

To find:

• The Mechanical Advantage

Solution:

• The Mechanical Advantage:

Mechanical Advantage = Load / Effort

Mechanical Advantage = 4500 / 1000

Mechanical Advantage = 4.5
