High-temperature gears weighing 150,000 N are being lifted from a furnace to an open environment with the help of a lifting arm made of steel, as shown in Figure (1). Frictionless belts are used for transporting. The portion of the lifting arm in contact with the gears is assumed to remain at 900 ºC, and heat is lost to the surroundings (20 ºC) via convection (film coefficient of 2.5 W/m2). For this exercise, determine the thermal stresses that develop from this temperature distribution and loading.
