simple mechanical calculator

enter the value and click "calculate", the calculation result will be displayed.

IMA = 2 × R₁ / R₁ - R₂
AMA = F_W / F_L
Efficiency = AMA / IMA
R₁ = radius of wider pulley
R₂ = radius of small pulley
F_w = load to be lifted
F_l = lift force exerted

simple mechanical calculator most people think of machines as complex items, such as bank machines, refrigerators, cars, or airplanes. however, any device that transmits or changes force or torque for a specific purpose may be called a machine. for example, screws and simple wheels are machines. a simple machine is a device with few or no moving parts that is used to perform work by changing force and motion. they are the simplest devices that use mechanical advantage (defined below) to increase strength. these devices are called simple machines.
