What is the MA of a hydraulic jack with a 1-inch pump piston and a 6-inch output piston.

Question

Quizplus · Accepted Answer

MA = output force/input force
The output piston is larger than the pump piston, so the output force will be larger than the input force. 
MA = 6/1 = 6 
Therefore, the MA of the hydraulic jack is 6:1 or 6/1. 
However, the choices given are in ratio form. To simplify the ratio, 6 can be divided by 2, resulting in 3 for the input (numerator) and 1 for the output (denominator). 
Thus, the simplified ratio is 3:1 or 3/1. 
To answer the question in the given format, the ratio needs to be flipped to input/output, resulting in 1/3. 
This can also be simplified to 33/1, so the answer could also be expressed as D. However, C is the best choice based on the given options.
