Can anybody tell me how to work out the deflection of a cantilever beam with a stepped diameter? I have looked through Roark's Formulas but can't seem to be able to do it The diameter of the beam would vary from 5mm to 3mm and back up to 5mm. I have attached a pic to explain. Thanks for...

surely you can use some of the engines heat energy to heat water into steam and run some of the car off steam. www.steamcar.co.uk/

I'm stuck on a beam bending problem I have. I have 2 cantilever beams one one top of the other applying a force. I need to know find the stress on the left hand beam and the deflection. I have the formulas (using Roark's formulas of stress and strain) but there's nothing about two cantilevers...

I asked a similar question. Take a look at this thread https://www.physicsforums.com/showthread.php?t=130414 Paddy

I found modern engineering mathematics and advanced modern engineering mathematics by Glyn James very helpfull. Should cover all the math you need

Can anybody tell me if there is a technical name for the balls that are used to float on a liquid surface to stop evaporation and heat loss? Thanks

so then how do aircraft fly perpendicular to the ground, or is there a component of the thrust equal to g?

thats awesome thanks guys! i'd like to see a 747 flying upside down :biggrin:

but doesn't the resultant lift always act in one direction relative to the "upper" surface so if its upside down won't the "lift" be downwards? Am i being stupid in saying this?:confused:

Can anybody tell me how aircraft fly up side down? I'm an under grad aero student and can't see how aircraft do. Can any aircraft theoretically fly up side down?:smile:
