Question

calculate the greatest and list pressure exerted by a metal block size 20 cm into 8 cm into 5 centimetre and having mass 5 kg

Answer 1

mass of block is 5 kg. so downward force is
f= mg=5*9.8=49N
max pressure at face 8*5 cm
p max= F/A=49/.08*.05
=12250 N/m^2
p min=49/.20*.08
=3062.5N/m^2
