Question

the force required to lift a load of 800 Newton by using a Lever having a mechanical advantage of 1.6 is​

Answer 1

Answer:force required to lift the load = 500N

Step-by-step explanation:

Mechanical advantage for a lever is given by the formulae

= force output/force input

or

Mechanical Advantage = Load / Effort

where

Force output / Load= 800 N

mechanical advantage = 1.6

Force input / Effort =??

Force input= Force output /Mechanical advantage

= 800N / 1.6

=500N

OR

Effort = Load/ Mechanical Advantage = 800/ 1.6 = 500N
