Calculate the pressure exerted by a brief which applies of a force of 2.5 Newton, when a) it is placed upright on the soil. b) when it is placed on its widest base. Dimensions of the bricks are 25cm*10cm*5cm

Answer»

Answer:since pressure=Force/Area

when it is placed upright its LENGTH and breadth will be 10 & 5 respectively

so area=10*5=50cm2=

0.005m2

Pressure=2.5N/0.005m2

=500N m-2

in CASE b it is placed on WIDEST base i.e. 25cm

so area =25*10=2500cm2

=0.25m2

Pressure=2.5/0.25=10N m-2
