Estimate the pressure exerted on a floor by (a) one pointed chair leg (60kg on all four legs)?

of area = 0.020 cm^2, and (b) a 1500kg elephant standing on one foot (area = 800 cm^2).

Estimate the pressure exerted on a floor by (a) one pointed chair leg (60kg on all four legs)?
(a)


Pressure


= (60 x 9.81) / (0.02 x 4)


=7357.5 Ncm^(-2)





(b)


Pressure


= Force / Area


=(1500x9.81) / 800


=18.4 Ncm^(-2)
