A rectangular wooden block has mass of 4 kg , the length , breadth and the height are 50 cm , 25 cm and 10 cm. Find the pressure on the table top when
(i) the surface 50 cm * 25 cm is placed
(ii) the surface 25 cm * 10 cm is placed
F=W=m.g
F=W =4*10(considering g as 10)
F=W =40N
a)
P=F/A
P=40N/50CM*25CM
P=40N/1250cm sq
P=40N/0.125m sq
P=320 N/m sq (Pa)
similarly for case (b)
F=W =4*10(considering g as 10)
F=W =40N
a)
P=F/A
P=40N/50CM*25CM
P=40N/1250cm sq
P=40N/0.125m sq
P=320 N/m sq (Pa)
similarly for case (b)
