1 - Under load P, the strain gauge mounted on the top of the beam at location B measures Ex = -300 μ. Elastic modulus E = 70 GPa. (a) Determine the stress components (Ox, Oy, Txy) at the point indicated at location A. The point is 30mm above the bottom face of the beam. (b) Draw the Mohr's circle depiction of the stress state at the same point. P y Im Im A 30mm Im Strain gauge B Im 120mm 301 x cross-section at location A
