Problem

A hydraulic press plunger exerts a thrust of

150\,\text{kgf}

on a square metal plate of side

5\,\text{cm}

. (i) Convert the given thrust into newtons, taking

1\,\text{kgf}=9.8\,\text{N}

. (ii) Determine the pressure produced on the plate in pascals. (iii) If the allowable working pressure for the plate is

6\times10^{5}\,\text{Pa}

, comment, with calculation, whether the plate is being used within the safe limit.
