Question

A block and tackle system has 3 pulley in the upper fixed block and 2 pulley in the lower movable block.what load can be lifted by an effort of 200N is the efficient of 100

I) what is the velocity ratio of the system

Answer 1

[AI-generated answer — Bot GPT 3.5]

To calculate the velocity ratio of the block and tackle system, we use the formula:

Velocity ratio = Number of pulleys in the fixed block x Number of pulleys in the movable block

Given that there are 3 pulleys in the fixed block and 2 pulleys in the movable block, the velocity ratio is:

Velocity ratio = 3 x 2 = 6

Therefore, the velocity ratio of the block and tackle system is 6.
