We constructed a half bridge with two strain gauges in order to capture the effect of maximum normal and shear stresses on a 60 cm steel cantilever beam with Young's modulus 200 GPa and Poisson's ratio 0.28, as shown in figure below. At the time that voltmeter recorded -0.32 mV, determine the load P applied to the free end of the cantilever beam that is a channel section with the dimensions as follow; C channel size; h = 25 cm, b = 7.6 cm, t1 = 1.2 cm, and t2 = 0.8 cm. Assuming that the excitation voltage (voltage source) used for the Wheatstone bridge was 1 V, and gauge factor of the strain gauges used in the Wheatstone bridge was 2.08. h a = 30° `P
