Bending Deflection at Given Points

AI Thread Summary
The discussion focuses on calculating beam deflection at specific points along a 1-meter beam. The user seeks assistance in determining deflection at 0.75m when a weight is applied at 0.5m, and vice versa. Additionally, they want to find the deflection at both points when equal weights are applied to both positions. The user is looking for equations or resources to help with these calculations. A link to a relevant resource is provided for further assistance.

Beam Deflection

I am trying to calculate beam deflection for a number of points?

I know the formula for maximum deflection, but i need to calculate the deflection when.

Lengh = 1m
Possition 1 = 0.5m
Possition 2 = 0.75m

- I apply a weight to possition one, and need to measure deflection at point 2.

- I apply a weight to possition two, and need to find deflection at point 2.

- I apple weights to both possition 1 and 2 (equal) and find deflection at 1 and 2.

If anyone can help me, or demonstrate how these equations are found, or just point me in some direction, i would appreciate it heaps...

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...
I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
