Ok so it seems I was on the right track. I know you can select any point, but I never understood why that is, but that's outside the scope of this question anyway. Thanks.
I assumed the reaction moment (Rm) would be at d/2, and from there got the following:
sum of moments about d/2 = 0 = P2L2 + P1L1 - Ra(d/2) - Rb(d/2)
P2L2 + P1L1 = Ra(d/2) + Rb(d/2)
(P2L2 + P1L1)/(d/2) = Ra + Rb; Ra = -Rb
clockwise moments are positive.
But I'm not sure this is correct...
Hey Eng-Tips,
I have a device mounted on a wall, which I'm trying to see if it can support. I have applied load P1 at the end, and component weight applied in the center, P2, at L1 and L2, respectively. The device has two supports, A and B, which I'm trying to find the horizontal reactions...
