A hydraulic press plunger exerts a thrust of 150kgf on a square metal plate of side 5cm.
a. (i) Convert the given thrust into newtons, taking 1kgf=9.8N.
b. (ii) Determine the pressure produced on the plate in pascals.
c. (iii) If the allowable working pressure for the plate is 6×105Pa, comment, with calculation, whether the plate is being used within the safe limit.
