Question

a stone slab of 60cm x 40cmx 20cm weighs 120 kg. it is placed on a table top. Calculate the pressure exerted by the stone stone slab on the table top if it is made to lie on the table with its sides of dimension 60cm x 40cm

Answer 1

orce applied by the Stone slab=Mass*Acceleration

=120*10

=1200 N.

1)Area of a face with sides 0.6m and 0.4m=0.4*0.6

                                                                  =0.24m2

                                                               

Pressure=Force/Area

            =1200/0.24

           =5000 Pa.

2)Area of sides=0.6*0.2

                       =0.12 cm2

Pressure=1200/0.12

             =10,000 Pa

3)Area of sides=0.4*0.2

                        =0.08 cm2

Pressure=1200/0.08

           =15,000 Pa
