moments problem Hi everyone, Just wondering if you could help with this problem a formula will do cos i don't know where to start. A steel beam 50 feet in length is suspended with pin connections at either end and bears a load of 6000 pounds in the centre. Its elasticity is 29 000 000 pounds per square inch and its moment of inertia is 850 pounds^4. How far is the beam deflected? Thanks iin advance for any help.
