Question

in a lever, the fulcrum is at one end at a distance of 20 cm from the load and effort is at the other end at a distance of 60 cm from the load. find the length of the load arm, effort arm, and the mechanical advantage of the Lever ​

Answer 1

Answer: 4

Explanation:given:

load arm = 20cm

effort arm = load arm +distance

                    {20+60}[cm] = 80

mechanical advantage= effort arm divided by load arm

80 divided by 20

4
