An aluminum cylindrical strain gage load cell is to be specified tomeasure a force of 100,000lbs. The maximum stress in the metal isto be 20,000 psi, the modulus of elasticity is 9.5 x 106psi, and Poisson' ratio is 0.33. What must be the wall thickness of a 6 inch outside diameter cylinder?
If it is instrumented with four active strain gages on awheatstone bridge, two axial and two transverse as shown, with S,i.e. strain gage factor of 2.1, initial resistance of strain gagesR = 350 Ω, and the power supply is 10V, what will be theoutput at the maximum load?
