A 60° strain rosette is mounted on a steel shaft. The following readings are obtained from each gauge:

ε_a = 0.000244, ε_b = 9.9E-5, ε_c = -0.0002 

Determine the corresponding normal and shear strains, and draw the strain block.

Assuming plane stress conditions, use the constitutive equations to find the corresponding stresses.

Assume E = 200,000 MPa and ν = 0.3.

Note: Do NOT round off any values until the final answer.

What is the value of strain in the x direction?

Present your answer using exponential format/scientific notation with 4 significant figures. 

e.g. 222.0E4 or 2.220E6
