Discover how pulleys make lifting easier by spreading out force and changing direction. This science extra explores simple machines in action breaking down how pulleys work and where we use them every ...

In this paper we present experimentally obtained cable-pulley Coulomb and viscous friction for cable-driven surgical robotic systems including the RAVEN II surgical robotic research platform. In the ...

The ingenious minds at Primitive Technology build a belt and pulley system that boosts their forge blower to an impressive 1200 RPM by hand.
