Question

Anvils made of single crystals of Diamond with the shape of its own in figure are used to investigate behaviour of materials under very high pressures. Flat faces at the narrow and of the animal has a diameter of 0.5 mm and the wide and are subjected to be comparison force of 50000 N. What is the pressure at the tip of the angle .

Answer 1

The compression force is same at each cross section of crystal .

Pressure = compression stress

= F/A = F/ pai r^2

Here , F = 50,000N, r= D/2 = 0.5 mm/2

= 0.25 ×10^-3 m

pressure P = 50,000/3.14 × (0.25 ×10^-3)^2

= 2.5 × 10^11 Nm^-2
