Answer to Question #71543 in Mechanics | Relativity for jojo

Question #71543
In a stamping machine the die has a mass of 30 kg and falls freely a distance of 2 m to strike a metal block. The depth of indentation is 10mm. Assuming that the die does not rebound Determine the average resistance of the metal. You are required to compare and contrast by solving this problem in two ways:
a) by making use of the principle of conservation of momentum and D’Alembert’s principle
b) by making use of the principle of conservation of energy.

Using diagrams to illustrate your answers, describe the following failure modes and the scientific principles that relate to them: 1. ductile/brittle fracture 2. fatigue 3. creep. For each, make reference, where appropriate, to loading conditions, grain size, surface finish, stress concentrations, the appearance of the failed surface, stages of creep, effects of temperature.
