Check out this online mechanical advantage of a screw calculator to know the mechanical advantage of a screw within fractions of seconds.

Screw: A simple machines with helical ridges and head is called as a screw. The helical ridges are called a thread.

Mechanical advantage of a screw: The ratio of output to input force of a screw is called as its mechanical advantage. Since, it is essentially a long incline wrapped around a shaft, so its mechanical advantage can be approached in the same way as the incline. When its pitch is smaller, the mechanical advantage will be greater.

Make use of this online screw mechanical advantage calculator to get reliable results on the ratio of output to input force of screw calculations.

Example:

Calculate the mechanical advantage of screw for the following data :
Diameter of screw = 25 cm
Distance between the threads = 30 cm

Solution:

Mechanical advantage of screw = (Π x 25) / 30
= 2.618
