8-0.25 mm L-250 mm Brass C36000, hard SITUATION 2: The brass bar shown is part of a conveyor that transports components into an oven. Initially, when the temperature is 15°C, there is a total clearance of 0.25 mm between the end of the bar and the inside of the frames on both sides. Consider the frames to be rigid and that they do not change dimension as the temperature rises. For the Brass C3600: a = 20.5 x 10°/°C, E = 110 GPa, and yielding strength = 310 MPa. 1. Calculate the maximum temperature (°C) for which there is no stress in the Brass. Frame 2. If the temperature rises to 90 °C, calculate the stress (MPa) in the Brass. Frame 3. If the maximum expected temperature in the Brass is 100 °C, calculate the factor of safety against yielding. ANSWERS: 48.78 °C; 59.125 MPa; 3.796
