Calculate beam reaction

Find the reactions indicated in the beam diagram. ( ∑M = 0 ; Moment sum of loads and resisting reaction is equal to zero.)




Answer: (2.5ft)(400lbs x 5ft) + (2300lbf)(12ft) + (5000lbf x 19ft) - (15ft)R2 = 0 ft-lbf, thus R2 = 8,507 lbf. R1 = (400lbf x 5ft) + 2300lbf + 5000lbf - 8,507 lbf = 793 lbf
