5. A jackscrew with a handle 30.0 cm long is used to lift a car sitting on the jack. The car raised 2.0 cm with every full turn of the handle. What is the ideal mechanical advantage of the jack?
5. A jackscrew with a handle 30.0 cm long is used to lift a car sitting on the jack. The car raised 2.0 cm with every full turn of the handle. What is the ideal mechanical advantage of the jack?  `IMA = (2πR)/P`
`IMA = 94`
Given:
`R = 30.0\ cm`
`P = 2.0\ cm`
Equation:
`IMA = (2πR)/P`
Solution:
`IMA = (2π(30.0\ cm))/(2.0\ cm)`
`IMA = 94` |
