Question

7. Calculate the mechanical advantage of a crowbar of length 350 cm if its fulcrum is at a distancw of 50cm from the effort​

Answer 1

Answer:

Ans-6

Explanation:

Given ÷

Length of crowbar=350cm

fulcrum arm = 50cm

To find

Mechanical advantage,MA =?

Solution

We know,

MA = effort arm length

fulcrum arm length

[effort arm = length of crowbar- fulcrum arm]

=> 350 - 50

50

=> 300

50

=> 6
