MecMovies 4.0 : M5.7: Rigid Bar and Two Axial Members

scene 11 of 14

The figure shows the deflection suffered by the rigid bar. The deflections at the points C and D are v subscript C and v subscript D.

To find the rigid bar deflection at $D$ , once again use similar triangles:

$\frac{v_{C}}{760 mm} = \frac{v_{D}}{1, 520 mm}$

$v_{D} = v_{C} \frac{1, 520 mm}{760 mm} v_{D} = 2 v_{C}$
