Deflection equation for a beam
WebThe first case is a trivial case, it corresponds to no deflection, and therefore no buckling – it describes the case when the axially applied load simply compresses the beam in the x direction. For beam buckling, we're interested in the second case, i.e. cos (kL)=0. Cosine is a periodic function, and we know that cos (x)=0 at intervals of pi ...

WebIf you decide deflection is more important insert the value for y which is the maximum allowable deflection for this part of your component. If stress is more important (ie you don't care how much it moves but you don't want it to break) then you need to use the stress equation not the deflection one and solve for the yield stress (or ... WebWhen measuring along the beam from left to right, x is taken as +ve. 2. Deflection y is +ve downwards. 3. Bending moment M is positive (+ve) when sagging. 4. Slope is +ve if while going from left to right along the beam tangent to the elastic curve while inclined downwards. Below: Distance x; deflection y; bending moment M and slope A are positive.
WebJul 24, 2024 · The formula for maximum deflection of a simple supported beam with point load at center is P*L^/48EI. For mild steel, E = 2.9e7. The tube has 1.9" OD and 1.61" ID, which gives its area moment of inertia as 0.310 in^4. Thus the maximum deflection is 0.23".
