Question

A screw driver acts as a lever when used to open a paint can. If Juan applies a force of 25 N to the handle of the screwdriver. What mechanical advantage does the screwdriver provide if it applies a force of 350 N to the lid?

Answer 1

Answer:

MA=14

Explanation:

Given that

Force input ,F= 25 N

Force output ,F' = 350 N

We know that mechanical advantage(MA) is the ratio of force input to the force output.Mechanical advantage is given as

$MA=\dfrac{F'}{F}$

Now by putting the values in the above equation then we get

$MA=\dfrac{350}{25}$

MA=14

Therefore the mechanical advantage will be 14.
