Inclined plane
A pulley is a wheel on an axle or shaft that is designed to support movement and change of direction of a taut cable or belt, or transfer of power between the shaft and cable or belt.
`IMA = F_(out)/F_(i n) = (mg)/(mgsinθ) = 1/(sinθ)`
`sinθ = H/L` => `1/(sinθ)=L/H`
`IMA`of inclined plane
`IMA = 1/(sinθ)` or `IMA = L/H`
