Figure P2.79 shows an aluminum cantilevered beam loaded by the force F. Strain gauges R1, R2, R3, and R4 are attached to the beam as shown in Figure P2.79 and connected into the circuit shown. The force causes a tension stress on the top of the beam that causes the length (and therefore the resistance) of R1 and R4 to increase and a compression stress on the bottom of the beam that causes the length (and therefore the resistance) of R2 and R3 to decrease. The result is a voltage of 50 mV at node B with respect to node A. Determine the force if
Find:
The force applied on the beam.
Assumptions:
Gage Factor for Strain gauge is 2
