Question

The radius of the press cylinder in a hydraulic press is equal to the diameter of its pump cylinder. Its mechanical advantage is _________ .
A. 1
B. 2
C. 3
D. 4

Answer 1

Correct Answer - D
Mechanical advantage of hydraulic press (M.A)
`=(("Radius of press cylinder")^(2))/(("Radius of pump cyclinder")^(2))`
`"But r"_("press")=("diameter")_("pump")=2" r"_("pump")`
`:.r_("press")//r_("pump")=2`
`:.M.A.=((2)^(2))/((1)^(2))=4`
