Beam
Deflection by Double Integration
(continued)
For 0
≤ x ≤
L/2 Determine moment
distribution in section 1 of beam. ccw ∑ M Q1 =
0 gives M1 ˗
(3wL/8) x + wx (x/2) = 0 So the moment distribution
in section 1 is M 1 = 3wLx/8 ˗
wx2/2 |
For L/2
≤ x ≤
L Determine moment
distribution in section 2 of beam.
ccw ∑ M Q2 =
0 gives M2 ˗
(3wL/8) x + (wL//2)(x ˗
L/4) =
0 So the moment distribution
in section 1 is M2 = wL2/8 ˗ wLx/8 Click here to continue
this example. |
