Question

The diagram below shows a wooden block of dimensions 8 cm × 10 cm ×12 cm. Its weight is 12 N. On which side should the wooden block be placed to produce a maximum pressure exerted on the table. What is value of this pressure ?

Answer 1

PRESSURE = FORCE/AREA

So, pressure will be maximum if the block is placed with least area under .... i.e. 8cm × 10cm

now the value of max. pressure will be given by P=F/A

P = 12/(8×10^-2)(10×10^-2)

P = 1500 N/m^2
