Please solve this exercise and thank you exerc'se:
A hydraulic press is a U tube, whose branches' sections are unequal, Sl = IOcm2 and
S2 — 50cm2, containing oil.
The free surfaces of oil are pressed by the pistons as indicated in the figure (a).
'Itie mass of the small piston is ml — 5kg and that of the large piston is m2 (unknown).
l- a. Calculate the pressure exerted by the small piston on oil.
Take g = ION'kg.
b. Give the pressure exerted by oil on the large piston.
2- Determine the mass m2 of the large piston, if the two pistons are On the same level.
3- We remove the large piston, the level of oil in the large branch rises a height h as
indicated in the figure (b).Caleulate h.
Given the density of oil 7500kg/m3.
