By using a strain gage that is connected to a beam, the strains can be measured at that point. Then by using certain formulas, the stresses can be calculated. This is what is being done in this experiment. A strain gage is connected to a beam and then a load is applied to the end which creates stresses. The main objective is to measure the stresses at a certain point of the beam. Wheatstone Bridge circuits are used to measure the resistance change of the strain gage due to the applied load. Strain rosettes are used for determining the principal directions and stresses in combined torsion and bending of the end of the shaft. The stress will be measured at both 400 lbs and 800 lbs. The readings from the strain indicator are given for each strain gage and each load. The reading can then be recorded and used to calculate the stresses.
