Question

an effort of 25kg is applied to a simple machine having velocity ratio of 4 and efficiency 15 Percent the mechanical advantage is​

Answer 1

Hey Dear,

# Mechanical advantage -

It is the ratio of the load to efforts applied.

◆ Answer -

Mechanical advantage = 0.6

● Explaination -

Efficiency of a simple machine is calculated as -

Efficiency = Mechanical advantage / velocity ratio

15 % = Mechanical advantage / 4

Mechanical advantage = 4 × 15/100

Mechanical advantage = 0.6

Therefore, mechanical advantage is 0.6 .

Hope this is useful. Thanks for asking...

Answer 2

Answer:

Explanation:

Advantage = efficiency ×velocity ratio /100 = 0.6

And to find load

Load = effort × advantage

= 25 × 0.6 =15 N
