Mechanical devises
-
lever
a fixed rigid beam requiring a fulcrum, load and effort to provide mechanical advantage
velocity ratio
the ration between the distance moved by a driving part of a machine and the distance the component is drives is over in the same time. it determines output speeds.
follower
a device that follows the movement of a calm profile to provide a desired output in a connecting part.
force
a push or pull upon an object that, when unopposed, will change the object's motion
friction
the resistance to movement between two surfaces that are trying to slide against each other. increased friction generates heat.
cam
a mechanism for converting rotary motion into reciprocation or oscillation (up and down/ back and forth) motion.
