A strain gauge has a nominal resistance of 350 \Omega with a gauge factor of GF=1.8 and senses axial strain. The gauge is mounted on a 1.0 cm^2 aluminum rod (Modulus = 70 GPa). Output voltage is measured as E_o = 1.0 mV and the circuit is supplied at E_i = 5.00V. Solve: Assuming the bridge is balanced at no load, calculate the applied load, assuming uniaxial tension. Enter the load in N. You can assume that the gauge is arranged such that a uniaxial load will produce a positive change in voltage.

Respuesta :

Answer:

The applied load = 3111 N

Explanation:

See the attached files for the calculation
