A small aluminum alloy [E = 75 GPa] tee shape is used as a simply supported beam as shown. For this beam, a = 160 mm. The cross- sectional dimensions of the tee shape are b = 21 mm, d= 32 mm, and t = 4 mm. After loads are applied to the beam at B, C, and D, a compressive normal strain of 460 µɛ is measured from a strain gage located at c = 7 mm below the topmost edge of the tee stem at section 1-1. What is the applied load P?
