a screwdriver with a 1-cm shaft and a 4-cm handle is used to tighten a screw. calculate the ideal mechanical advantage.

Respuesta :

Ideal mechanical advantage = Effort distance/Resistance distance

In the current scenario,
Effort distance = 4 cm
Resistance distance = 1 cm

Therefore,
Ideal mechanical advantage = 4/1 = 4

Answer:

IMA = Distance of Effort/ Distance of resistance

Explanation:

M.A is the force amplification of a machine.

Ideally, a screw driver has varying diameters on two ends, the shaft and the handle, however, since the question does not provide those parameters, we will assume shaft and handle have the same diameter.

DE = 4

DR = 1

Therefore, IMA = [tex]\frac{4}{1} = 4[/tex]

If diameter is given, IMA is calculated by

Area of Effort/ Area of resistance i.e. AE/AR
