Homework Statement
Hi, i am trying to understand how to find the reactions (Ra & Rb) and moments (Ma & Mb) of the beam shown in the sketch below. Not an exact number but in terms of Mo(couple moment) and L(length).Homework Equations
I have the answers which are Ra = -Rb = 3Mo /2LAND Ma = -Mb = Mo/4
The Attempt at a Solution
taking moments about B: Ma - Ra(L) + Mo - Mb = 0
After that i broke the beam into 2 pieces (in the middle of the beam)
took the elastic equation for both sides where:
Mx = Ra(x) - Ma (left side)
Mx =Rb (x) - Mb (right side)
Intergrated both equations twice and found C1 and C2,and set these 2 equations equal for x= L/2 (as the delfection in the middle is 0)
But i can't get this result
Have i done something wrong?
