e.g. a rope or cable. In addition, pulleys can be "added together" to create mechanical advantage, by having the flexible material looped over several pulleys in turn. More loops and pulleys increases the mechanical advantage.

These simple machines provide a mechanical advantage by changing the direction or magnitude of a force. Simple machines can be combined with other devices to form more complicated machines and can thus be considered the building blocks of engineering. ...
Simple machines are devices that are not powered and help humans do work by adding a mechanical advantage. The six simple machines are inclined planes, levers, wheel and axles, pullies, wedges, and screws. All Classical Mechanics Topics
" according toGeorgia State University. Many devices use screws to exert a force that is much greater than the force used to turn the screw. These devices include bench vices and lug nuts on automobile wheels. They gain a mechanical advantage not only from the screw itself but also, in ...
Mechanical model of mate-grasping in Gerris gracilicornis Model description We applied standard methods used in robotics for calculating grasping forces of mechanical devices. We used a 2 D model for calculating maximum pulling force by a male as a function of the size ratio between the male an...
