A 60 kg girl wearing high heels shoes balance on a single heel. The heel is circular with a diameter of 15 cm. Find the pressure exerted by the heel on the horizontal floor |
|
Answer» -★ Given:-RADIUS of the heel, r = = 0.004mMass of the lady, m = 60 kgDiameter of the heel, d = 0.8 cm = 0.008 MAREA of the heel, A = πr² = π (0.004)²= m²★ Force on the floor due to the heel:-F = MG = 60 × 9.8 = 588 N★ Pressure EXERTED by the heel on the floor:-P = = P = Nm-²Hence, the pressure exerted by the wheel on the horizontal floor is Nm-² |
