2. For the given wheel and axle, find the magnitude of `F_(i n)`.
2. For the given wheel and axle, find the magnitude of F_(i n). `F_(out)R_(out) = F_(i n)R_(i n)`
`F_(i n) = 20\ N`
Given:
`F_(out) = 100\ N`
`R_(i n) = 50\ cm`
`R_(out) = 10\ cm`
Equation:
`F_(out)R_(out) = F_(i n)R_(i n)`
Solution:
`F_(out)R_(out) = F_(i n)R_(i n)`
`F_(i n) =F_(out)R_(out) / R_(i n)`
`F_(i n)= (100\ N)(10\ cm)/(50\ cm)`
`F_(i n) = 20\ N` |
