Question

The length of a Class I lever is 2 m. Calculate its mechanical advantage if the fulcrum is at a
distance of 40 cm from the effort point.​

Answer 1

Answer:

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/160 = 0.25

Answer 2

Explanation:

Calculate its mechanical advantage if the fulcrum is situated at a distance of 40 cm from the effort. ... Length of the lever 2m = 200 cm ... Length of the load arm 200 cm − 40 cm = 160 cm
