The title is fairly misleading but is within the subject. I have drawn up a beam of my own as part of my classwork because what bothers me is how you would find Young's Modulus [E] and the second moment of inertia without being given them. Every question I have looked at has given me the two values combined hence, EI. The beam I have drawn is 10m long. From the LHE going right, 2m in is a 90kN point load, 3.5m in from LHE is a 8kN point load, from 2m in from LHE across by 3m is a UDL 12kN/m, and 7.5m in from LHE is a final point load of 10kN. RL = 103,1kN and RR = 40.9kN In order for me to find ymax at the mid-point of the beam I require an EI value which because it's a beam I made myself, I do not have. What I have available that I think was relevant: a sheet that shows me data for different types of beams, with D x B, Ixx and Zxx values. The bending equation: E/R=sigma/y=M/I Ixx=bd^3/12 I had a go at this over 6 weeks ago and I got my E and I values, however I've lost the notes that have the calculations on them. The values I got were, E = 200x10^9N/m and I = 2.9....x10^-3cm^4 All I am asking here for is the route / method taken to find the E and I - not EI, but the two individual values for the beam described above. I would use symbols to draw the beam here but it would look a mess, but then again: RL = 103.1kN |_2m_| 90kN_1.5m_| 8kN_3m_| 12kN/m[UDL] _2.5m_| 10kN_2.5m_| RR = 40.9kN |____||______|______| (Looks similar to this) So if you know how to do all this just imagine your given this beam mainly to find the slope and deflection - which I know how to do. Unfortunately you need an EI value, to find that you need both E and I. If you know the method please share it here because my mind is blank haha.
