Question

A mover uses a ramp to push a stereo into the moving van. The ramp is 3 meters long and 1.5 meters high. What is the ima of this ramp?

Answer 1

Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanicaldevice or machine system. Ideally, the device preserves the input power and simply trades off forces against movement to obtain a desired amplification in the output force. The model for this is the law of the lever. So the ima is 3/1.5 = 2
