A cantilever type thermostat has the following characteristics: K, = 1.45 x 105 /°C; F, = 48 GPa; L = 55 mm, width = 55 mm; total thickness = 0.8 mm. For a temperature change of 130°C, calculate (a) the deflection at the free end if there is no restraining force, (b) the maximum stress in the element at maximum temperature, (c) the restraining force at the free end for no deflection, when the thermostat is subjected to a temperature rise, AT = 130°C. 120mm A cantilever type thermostat has the following characteristics: K, = 1.45 x 105 /°C; F, = 48 GPa; L = 55 mm, width = 55 mm; total thickness = 0.8 mm.
