A rectangular strain gauge rosette was employed to determine o = 4350 psi and o = 1450 psi, as shown below. Calculate the magnitude of o, o and t if 0 = 30°. Note: A rectangular strain gauge rosette can be used to measure the strains and then help determine the in-situ stresses, we will discuss the use of a strain gauge later in the class, but it does not impact stress calculations here. y 02 01
