MecMovies 4.0 : M5.8: Rigid Bar with Opposing Members

scene 12 of 13

The figure shows a rigid bar A B C D with its right end inclined downwards. The supporting bars at B and C are elongated and compressed respectively. The load at the right end of the bar is P directed vertically downwards. The deflection at the right end is v subscript D directed vertically downwards.

Summary of results:

Member forces:

$F_{1} = + 19.466 kN F_{2} = - 28.030 kN$

Member normal stresses:

$σ_{1} = 121.7 MPa (T) σ_{2} = 175.2 MPa (C)$

Rigid bar deflection at $D$ :

$v_{D} = 3.38 mm$
