Hi guys, i'm new to the physics world and am getting a bit confused with some of the terms used, stopping me getting the maths i need. Essentially I need to measure the deflection at the end of a beam, supported at one end. Like this: http://upload.wikimedia.org/wikipedia/commons/e/e9/Cantilever_Beam.svg I will have the beam at different angles with different weights on the end and different gravity. So essentially what i need is a formula where i can specify: Gravity Beam Angle Beam length Beam end weight and obtain a deflection. I'm guessing i will initially have to measure the deflection to obtain information on the strength of the material. Then use this value to calculate future deflections based on weight. Thanks for any input you guys might have!
