1. The problem statement, all variables and given/known data The calculation for the maximum bending moment is to be verified experimentally using a strain gauge bonded to the outer surface of the beam, at the point where the maximum bending moment occurs. Derive an equation which could be used to calculate the bending moment from the measured strain value. State the meaning of all symbols used in your equation. 2. Relevant equations M / I = σ / y = E / R Stress = Force / Area = F/A strain = Change in Length / Original Length 1 / R = M / EI can anyone provide some guidance?
