Question

While Lifting a load of 200m using a lever, an effort of 80N moved through distance of 20 cm to lift the load through a distance of 4 cm.calculate the mechanical advantage​

Answer 1

4

Step-by-step explanation:

Velocity Ratio is the distance moved by effort ÷ distance moved by the load which is 20/4 = 5

Effort= Mechanical Advantage/ Velocity Ratio × 100/1

80/100 = x/5

80 × 5 = 100x

400 = 100x

x= 4
