Slider-crank linkage

 &#; A slider-crank linkage is a four-link mechanism with three revolute joints and one prismatic, or sliding, joint.[1] The rotation of the crank drives the linear movement the slider, or the expansion of gases against a sliding piston in a cylinder can drive the rotation of the crank. There are two types of slider-cranks: in-line and offset. In ...

FUNdaMENTALS of Design

 &#; you apply the force of your muscles over a much longer distance, so the cutting force acting over a small distance of travel becomes very high. What differentiates bolt cutters from a simple giant size pair of wire cutters, is that the bolt cutters have a linkage that allows them to achieve in a much smaller space the amplification of force.
