PLAIN AND CIVIL: EXAMPLE 4.3.2. BEAM SUPPORT REACTIONS FOR CONCENTRATED LOADS

Determine the reactions on the beam with the following applied concentrated load.

Determine the hinge and roller unknown reactions. 2 for the hinge and 1 for the roller.

$\sum F_{X}=0]\rightarrow$

${\color{Red} \mathbf{R_{AX}=0}}$

$\sum M_{E}=0$

$R_{AY}\left ( 72ft \right )-18lb\left ( 47ft \right )-35lb\left ( 35ft \right )-20lb\left ( 15ft \right )=0$

${\color{Red} \mathbf{R_{AY}=32.931lb}}$

$\sum M_{A}=0$

$18lb\left ( 25ft \right )+35lb\left ( 37ft \right )+20lb\left ( 57ft \right )-R_{E}\left ( 72ft \right )=0$

${\color{Red} \mathbf{R_{E}=40.069lb}}$
