Question

the length of a class 1 lever is 2 m calculate its mechanical advantage if the fulcrum is at a distance of 40 cm from the effort point​

Answer 1

Explanation:

Length of the lever 2m = 200 cm

Length of the effort arm 40 cm

Length of the load arm 200 cm — 40 cm = 160cm

Mechanical advantage ?

We know that,

Mechanical advantage = Length of effort arm / Length of load arm

MA = 40cm /160cm = 0.25 is the answer
