Question

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

Answer 1

Answer:

=> 0.25

Explanation:

Length of the lever 2m=200 cm

Length of the effort arm 40 cm

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

Mechanical advantage ?

We know that,

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

MA=

160 cm

40 cm

=0.25
