Anvils made of single crystals of diamond, with the shape as shown in figure, are used to investigate behaviour of materials under very high pressures. Flat faces at the narrow end of the anvil have a diameter of 0.50 mm, and the wide ends are subjected to a compressional force of 50,000 N. What is the pressure at the tip of the anvil?

Explanation

Diameter of the narrow end (i.e., tip) of the anvil,
`D=0.5 mm = 5xx10^(-4)m`
Area of the tip, `A=(piD^(2))/(4)=2xx10^(-7) m^(2)`
Force, `F=5xx10^(4)N`
Pressure at the tip, `P=(F)/(A) = 2.5xx10^(11) Pa`.
