Question

A brick with dimensions 3cmx1.5cm x 6cm and mass 4 kg is lying on the ground. Calculate: i)Least pressure exerted by the brick. ii)Maximum pressure exerted by the brick.

Answer 1

maximum pressure exerted by brick of area 3*1.5cm

mean area is 4.5cm²

force is equal to mass 4kg

so p=mass/area

p=4/0.045m

p=89

Pascal

similarly minimum pressure

p=4/6*3/100

p=33.4 pascal
