Question

A cantilever beam with a rectangular cross section (width b = 20 mm, height Ii = 175
mm) is loaded by a force P that acts at the mid-height 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 mid-height of the beam. Gage A measures the strain in the horizontal direction,
and gage B measures the strain at an angle = 600 to the horizontal. The measured
strainsaree A = 145 X 10_6 and 68 = —165 X lO_6.
Determine the force P and the angle a, assuming the material is steel with £ = 200 GPa
and v = 1/3.
