How is the mechanical advantage of composites measured? Two parameters are generally used to measure the relative mechanical advantage of composite materials. One parameter is called the specific stiffness and is defined as the ratio between the young’s modulus (E) and the density ( ρ ) of the material.

How Do You Calculate Mechanical Advantage? | Reference.com

In the case of a screw, the mechanical advantage is the ratio of the circumference of the screw to the distance traveled after each revolution. In other words, IMA = 2*pi*L / P, where L is the radius of the screw and P is the distance traveled after each revolution.

Simple Machines -- Mechanical Advantage - Edinformatics

The mechanical advantage can be calculated for the following simple machines by using the following formulas: Lever : MA = length of effort arm ÷ length of resistance arm. Wheel and axle : A wheel is essentially a lever with one arm the distance between the axle and the outer point of the wheel, and the other the radius of the axle.

Mechanical advantage is a ratio defined as a simple machine's output force to input force. Simple machines are systems that trade work for work, re-formatting the work to either reduce the input force required, or alternatively if desired, extend the distance of motion of the output more than that of the input.

Mechanical advantage of a screw. A typical screw consists of two parts: a threaded cylindrical shaft and a head. To determine the mechanical advantage, you will need two characteristics of the thread (helical ridges on the screw): Diameter of the screw shaft, and; Lead of the thread. In simple screws, the lead is equal to the distance between two adjacent threads.
