1. A strain gage rosette is an electromechanical device that can measure relative surface elongation on three directions. Bonding such a device to the surface of a structure allows determination of normal strain along the gage arms. Such a rosette is mounted on the surface of a stress-free elastic solid as shown at the right. Upon loading, the three gage readings are 30 a30 Ea-300 x 10-6, ε,-400 x 10-6, ε.-100 x 10-6 Assuming the material is steel with E-207...

Part A - Question 3 (Total Marks for Part A - Question 3:20) A steel beam in an industrial structure is part of a complicated frame that was difficult to analyse. Using a rectangular strain gauge rosette, the actual strains at point A have been recorded while being subjected to test loads. It is necessary to determine the normal stresses and shear stresses in the actual beam subject to the test loads to check whether the stresses assumed in the...
