Question

In a certain machine a force of 5N move down a distance of 0.07m in order to raise a load of 50N through a height of 0.7cm. Calculate velocity ratio (V.R)

• A. 10
• B. 500
• C. 0.1
• D. 5000

Answer 1

The correct option is A 10

Given,

Effort distance = 0.07m = 7 cm

Load distance = 0.7 cm

Therefore,
Velocity ratio = Effort distance / Load distance
= 7 / 0.7
= 10
