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?

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

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

MA=14

Therefore the mechanical advantage will be 14.

at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.

this is poiselle's equation from fluid mechanic in physics. mech eng
