Advantages & Benefits of Using Composite Materials

In addition, because thermoset composites have a low petroleum-based content, they are not subjected to the price fluctuations experienced in petroleum-based products. Lower material costs Because thermoset composites can be precisely molded, there is little waste and therefore significantly lower overall material costs than metals products.

Lever - Wikipedia

A lever amplifies an input force to provide a greater output force, which is said to provide leverage. The ratio of the output force to the input force is the mechanical advantage of the lever.

Mechanical advantage - Wikipedia

Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system. The device preserves the input power and simply trades off forces against movement to obtain a desired amplification in the output force. The law of the lever•Speed ratio•Gear trains•Chain and belt drivesLevers and Mechanical Advantage - 8th Grade Integrated Science

To calculate the mechanical advantage of levers, you can use one of 2 formulas. 1. Mechanical Advantage = Effort Distance / Resistance Distance (MA = ED/RD) This formula is used when you are given meters. The effort distance is the distance from the effort to the fulcrum. In the picture to the left that's dE.
