Question

A brick 20cm long 10cm wide and 5cm thick has a mass of 500g,Determine the (take g=10kg-1)Greatest pressure that can be exerted by the brick

Answer 1

pressure =force/area

and force = mg

f= 0.5×10= 5N

brick has six faces

the face which has less area have more pressure.

face with side 10×5 has lowest area =50.

so greatest pressure = 5/ 50= 0.1

answer 1/10 = 0.1
