1. A material has stress-strain diagram as shown in Fig. 1. It has equal yielding stress and proportional limit stress. Determine mechanical properties below: • Proportional limit: _MPa (0.5pts) • Ultimate stress: _MPa (0.5pts) • Fracture stress: _MPa (0.5pts) • Modulus of elasticity: GP (Ipts) • Modulus of resilience: _MJ/m?
