Anvils made of single crystals of diamond, with the shape as shown in the figure, are used to investigate the 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?
1. \(2.5\times10^{11}\) Pa
2. \(3.7\times10^{11}\) Pa
3. \(2.1\times10^{11}\) Pa
4. \(1.9\times10^{11}\) Pa
1. | \(0.7\) m from wire \(A\) |
2. | \(0.07\) m from wire \(A\) |
3. | \(7.0\) m from wire \(A\) |
4. | \(0.007\) m from wire \(A\) |
Two strips of metal are riveted together at their ends by four rivets, each of diameter 6.0 mm. What is the maximum tension that can be exerted by the riveted strip if the shearing stress on the rivet is not to exceed 6.9× Pa? (Assume that each rivet is to carry one-quarter of the load.)
1. 7850 N
2. 6000 N
3. 7070.73 N
4. 7799.76 N
