Question

An object of weight `500 kg_(wt)` is lifted by using a hydraulic press. The radii of the cross sections of the pump piston and press piston are 10 cm and 20 cm, respectively. Calculate the effort required to lift the object. Calculate the displacement of the load if the effort is moved through a distance of 20 cm.

Answer 1

(i)` ("Load")/("effort")=(("radius of the lift pistion")^(2))/(("radius of the press piston")^(2))`
Work done on the load= Work done by the effort.
(ii) 5 cm.
