Question

the length of a lever is 3m.Calculate the mechanical advantage of the lever if its fulcrum is situated at a distance of 120 cm from the load.​

Answer 1

Answer:

3m length then load arm = 120 effort arm =170

ma= 170/120 =1.3(approx)

Answer 2

Answer:

2.5

Explanation:

Length of the lever = 3m = 300 cm

Length of the load arm = 120 cm

Length of the effort arm = 300

Mechanical advantage = length of the effort arm by length of load arm

= 300 cm = 2.5

120 cm
