Question

A block of iron of mass 7·5 kg and of dimensions 12 cm x 8 cm x 10 cm is kept on a table top on its base of side 12 cm x 8 cm. Calculate: (a) thrust and (b) pressure exerted on the table top. Take 1 kgf=10 N.​

Answer 1

Solution :-

Mass of Iron Block = 7.5 kg

Weight = mg

= 7.5 x 10 N

= 75 N

Area on which the thrust acts

= 12 cm × 8 cm

= 96 cm²

= 96 x 10 ^ -4 m²

Pressure exerted on the table top

= Force/Area

= 75 / (96 x 10 ^ -4)

= 7812.5 Pascal
