Problem 3. The horizontal beam is rigid. All
of the vertical deformable bars have length
L, area A, and Young's modulus E. The load P
is applied to the middle of the grey
deformable bar. Determine (a) the internal
force in each half of the gray bar, and (b) the
forces in the black deformable bars. Hint:
You will have to draw a separate free body
diagram for the gray bar and determine the
internal forces and deflections in each half.
You are also allowed to use symmetry. You
can also think about turning the entire
problem on its side.
