Beam
Deflection (Statically Indeterminate) -
Method of Superposition
Example: (continued) |
For compatibility the end
of the beam deflects the same for the beam and for the rod. ∆beam =
∆rod where ∆beam = qL4/8EI –
TL3/3EI and ∆rod =
TH/AE Solve for T. T = 3
q L / [ 8(1 + 3(I H / AL3 ) ] So the axial stress in the
rod is σ = 3
q L / [ 8(1 + 3(I H / AL3 )A ] |
