15\,\text{cm}

. The manufacturer specifies that the operating pressure on the piston surface must not exceed

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

. (i) Calculate the maximum permissible force that can act normally on this piston. (ii) A worker places a

100\,\text{kg}

weight on the piston. Taking

g = 9.8\,\text{m}\,\text{s}^{-2}

, state with calculation whether this weight stays within the safe limit.
