1. The problem statement, all variables and given/known data I have a 13 foot long beam supported by a pin at x = 0 feet and a roller at x = 9 feet. There is a triangular distributed load of 50 lb/ft from 0 ft to 9 ft. (Increasing as it approaches 9 ft) At the end of the beam there is a moment of 200 lb-ft counter-clockwise. 2. Relevant equations ƩFx = 0 ƩFy=0 ƩMr = 200 lb-ft Vertical Force at Pin: 52.78 lbs upward Vertical Force at Roller: 172.22 lbs upward Normal Force = 0 3. The attempt at a solution For the first section, it seems my equations are correct; 0 < x < 9: Shear: -.5(50/9)x^2 + 52.78 Bending: -.5(50/9)x^3/3 + 52.78x ---- This is where I'm having an issue with my Bending equation; 9 < x < 13: Shear: -225 + 52.78 + 172.22 Bending: 52.78x + 172.22(x-9) - 225(x-3) ----- At exactly 9 feet, both bending functions should give a bending moment of -200 lb-ft but for some reason, I can't seem to get that answer with the second one. I tried to rework this function a few times but it's not happening.
