1. The problem statement, all variables and given/known data So I have a beam here, I'll post a Photoshop diagram of the problem at the bottom of this section, but its an overhanging beam simply supported at one end, and mid way down another, points A and B. I've changed up the values so I can do my work myself, I don't want someone blurting the answer to me. I need to learn rather than cruise through my class. The beam is carrying a continuous uniformly distributed load that represents it's own weight of 4kN/m and two vertical loads of 16kN and 10kN The setup looks like this I'm to create a shear force and bending moment diagram for this beam. 2. Relevant equations So, my relevant equations are very simple, the sum of the moments = 0 because I'm in equilibrium, and so are the forces. I have these equations to work with; ∑M=0 ∑F=0 3. The attempt at a solution Well, to create my shear force diagram I decided to turn the UDL into a point load in the middle, considering I had a load of 4kN/m over 16 meters I ended up with 64kN in the middle of the beam at 8 meters. In hindsight I can see how this might not be right, considering it doesn't take into account support B but I don't know how to take it into account. It isn't at the end of the beam. Continuing on and hoping for the best I calculated my moments and did the following ∑MA=0 0= 0+(16*4)+(64*8)-(MB*5)+(10*16) 0= 64+512-(MB*5)+160 MB*5=736 ∴MB=736/5 =147.2kN Ok, so I have now the reaction force at support B. I can now use a different calculation to get ahold of A. if ∑F=0 then A= 64+512-147.2-160 =268.8 and from that I can set up a shear force diagram I'm not so sure is correct but I'll have to go with it. 1. The problem statement, all variables and given/known data so now the bending moment diagram. Time to work out my bending moments. 2. Relevant equations I'll take point A, and my equation is this MA=0 3. The attempt at a solution so what I have in this beam are a number of forces to work out bending moments from. I have support A 4 meters down the beam is force a at 16kN then the translated UDL is force b at 64kN, 8 meters away. support B exerting a force of 147.2kN upwards and force c exerting a force of 5kN 10m from A (Yes, I'm using capitals to represent supports and lowercase to represent force) so what I did is this MA=0 a= (16*4)+(64*8)-(147.2*10)-(10*16) =-1056 b=(64*4)-(147.2*6)-(10*12) =-747.2 B=-(147.2*2)-(10*8) =-374.4 c=-(10*6) =-60 and I get a simple weird bending moment diagram that doesn't fit my situation, you can see it'd be kind of this shape √. Means I don't really get whats going on unfortunately, I need some help with this. What am I doing wrong?
