(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The picture of the beam below has a module of rigidity EI, determine the reactions at the supports and the equation of the deflection curve of the left half of the beam

2. Relevant equations

v*EI=((M_{a}*x^{2})/2)+((R_{a}*x^{3})/6)

Ʃ of Forces in Y direction = R_{a}+R_{b}=0

Ʃ Moments about A = M_{a}-M_{o}+M_{b}-R_{a}*L

3. The attempt at a solution

How do I go about finding R_{a}and R_{b}and M_{a}and M_{b}?

For the left had side of the beam the bending moment equation is M_{a}+R_{a}*x

Putting x = L/2 in to the defelction equation gives me:

((M_{a}*L^2)/(8EI))=((-R_{a}*L^3)/(48EI))
