In summary, The conversation discusses finding the deflection at a specific point on a beam and the methods that can be used to solve it. The beam has a downward point load and a moment at specific distances from the left end. The two main approaches to solving this problem are the geometric and energetic methods, which include double integration, superposition, moment-area, conjugate beam, virtual work, and Castigliano's Theorem. It is suggested that the student pick one method and start working on it.
if anyone could provide any insight as to how i go about completing this question i would be grateful, i was off the week this was taught to the group and have no idea whatsoever
Well one is to find the deflection at 3m from the left end of a 6 m beam, which is therefore the midpoint.
There is a downward point load of 85 kN at 2 m from the left end and moment of 100 kN-m at 4 from the left end.
Do you know the convention on moment? The 100 kN-m moment will raise the portion of the beam on the left side, will lowering the portion of the beam on the right side, of the moment.
thats the thing, i had a berievement in the family and I was off college for a good time, just managing to catch up but this is in my way. missed the whole section on deflections
Usually a regular Mechanics of Material course will cover the three first geometric methods. An advanced course may include also Castigliano's Theorem.
