Energy and power
identifying the Six Simple machines
Lever: Is a simple machine that has a pivot point on an axle (like the one to the left) or on a fulcrum. Most commonly there is a smaller effort force which is trying to lift a larger resistance force. When both forces are equal that is called static equilibrium.
Equations:
IMA= distance of effort/distance of resistance
AMA= force of resistance/ force of effort
Efficiency= AMA/IMA
Equations:
IMA= distance of effort/distance of resistance
AMA= force of resistance/ force of effort
Efficiency= AMA/IMA
Movable Pulley: A pulley is
