A table has mass 5 kg. And its replaced on the floor. If the area of one foot’s table is 5 cm2. find the pressure that apply on it.

Answer»

Mass of the wooden block, m=5kg

Thrust due to wooden block,

Mg=5kg×9.8ms

−2

(a) SURFACE AREA of 20cm×10cm surface,

A=(20×10)cm

=(0.2×0.1)m

=0.02m

0.02m

49N

0.02

−2

or Pressure, P=2450Nm

−2

(b) Surface area of 40cm×20cm surface,

A=(40×20)cm

=(0.4×0.2)m

=0.08m

0.08m

49N

0.08

−2

or Pressure, P=612.5Nm
