Question

what mechanical advantage does a hydraulic press have when punching holes in a metal sheet with a force of 800N using only 200N ? provide answer as a ratio ​

Answer 1

Ratio is 1/4

Explanation: The thing is when using small force on such hydraulic presses you can get much more force than you used. The thing is a small force on small surface generates much much more force on bigger surface which is the main principle of hydraulic press. Therefore a hydraulic press can push holes in metal with a starting force of only 200 N
