Question

Calculate the effort to lift a load of 160 N by using a lever having a mechanical advantage of 0.4. Please answer.. it's urgent

Answer 1

Answer:

400N

Explanation:

MECHANICAL ADVANTAGE

$load \div effort$

HERE, M. A=0.4

LOAD= 160N

EFFORT=?

NOW, WE CAN SAY:

$0.4 = 160n \div effort$

BY INTERCHANGING POSITION OF M. A AND EFFORT WE GET:

$effort = 160n \div 0.4$

$effort = 1600n \div 4$

$effort = 400n$

THERE FORE EFFORT WILL BE 400N
