A cantilever beam of rectangular cross section (width b = 25 mm. height h= 100 mm) is loaded by a force P that acts at the midheight of the beam and is inclined at an angle a to the vertical (see figure). Two strain gages are placed at point C. which also is at the midheight of the beam. Gage A measures the strain in the horizontal direction and gage B measures the strain at an angle B = 60 to the horizontal. The measured strains are e 125 x 10 and e, -375 x 10-, Determine the force P and the angle a, assuming the material is steel with E- 200 GPa and = 1/3.
