PLAIN AND CIVIL: EXAMPLE 7.0.11. FINDING REACTIONS IN TRUSSES

Sunday 10 March 2019

Determine the reactions of the supports of the truss.

The roller at point A will have a horizontal reaction and the hinge at point B will have both the horizontal and vertical reaction.

$\sum F_{Y}=0]\uparrow$

${\color{Red} \mathbf{Ry_{B}=300lb}}$ upwards

$\sum M_{A}=0]$

$Rx_{B}\left ( 3ft \right )=-300lb\left ( 4ft \right )$

${\color{Red} \mathbf{Rx_{B}=400lb}}$ to the right

$\sum M_{B}=0]$

$R_{A}\left ( 3ft \right )=300lb\left ( 4ft \right )$

${\color{Red} \mathbf{R_{A}=400lb}}$ to the left
