Anvils made of single crystal of diamond, with the shape as shown in Fig. 4, are used to investigate behavior of materials under very high pressures. Flat faces at the narrow end of the to a compressional force of 50,000 N. What is the pressure at the tip of the anvil?

Answer:

Here, \[D=0.5\,\,m=0.5\times {{10}^{-3}}=5\times {{10}^{-4}}m\]                 \[=1\cdot 013\times {{10}^{5}}pa\] N \[V=100\]                 Pressure at the tip of anvil                                  \[=100\times {{10}^{-3}}{{m}^{3}};p=100atm.=100\]                 \[=100\times 1\cdot 013\times {{10}^{5}}pa.\] \[V+\vartriangle V=100\cdot 5\]\[\vartriangle V=\left( V+\vartriangle V \right)-\]
