Question

A hydraulic lift is designed to lift heavy objects of maximum mass 2000 kg. The area of cross-section of piston carrying the load is 2.25*10^-2 m^2 . What is the maximum pressure the smaller piston would have to bear?

(A) 0.8711 * 10^6 N/m^2
(B) 0.5862 * 10^7 N/m^2
(C) 0.4869 * 10^5 N/m^2
(D) 0.3271 * 10^4 N/m^2

Answer 1

Answer:

The area of cross section of the piston carrying the load is 425 cm². ... Maximum mass of a car that can be lifted, m = 3000 kg. Area of ... A = 425 cm^2 = 0.0425 m^ 2

Answer 2

Answer:

(C) O.4869 × 10^5 N/m^2
