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).
Hint
`F_(out)R_(out) = F_(i n)R_(i n)`
Answer
`F_(i n) = 20\ N`
Show Steps
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`
