Coil spring force line control is an important aspect of spring design for coil-over-shock suspension type applications, such as MacPherson strut and coil-over-shock trailing arm applications, from ...

Some forces are called contact forces because they require objects to touch. One is tension force, found in stretched wires. Another is the force found in a spring. And last are resistive forces: ...

Here’s the rub with friction — scientists don’t really know how it works. Although humans have been harnessing its power since rubbing two sticks together to build the first fire, the physics of ...
