are the safety protocols in place in setablishments dealing with fissionable material adequate for public safety? is there any good places to get more information on why the safety isn't good enough? =)

its not a question it is a part of a physics assignment of beam deflection.. i am trying to show for the formula (force x length^3)/(4 x young’s modulus x breadth x thickness^3) was derived. i know it was done through integration and the combining of the bending moment formula and the Torque...

i am finding the bending moment of a rectangular beam of plywood. the dimensions change due to altering the variables throughout the experiment.

Homework Statement what is the bending moment formula? is it related to the pure bending formula? what's that? Homework Equations The Attempt at a Solution is the formula 1/p=M/EI?

sorry.. the max deflection formula for a simply supported beam... :)

does anyone know how the formula for calculating max deflection was derived? The formula is (Force x Length^3)/(48 x E x I). I think it was through intergration but if anyone knows more could you please let me know? thanks! :)

does plywood follow hooke's law? is the young's modulus for plywood constant across the beam? :) and if u have any other hints with deam deflection I am willing to have them :P thanks!

hey is there a formula for compression and tension? if so would you be able to let me know what they are? thanks! :)

How are sine waves converted to current?? Im doing avionics in physics at the moment and we are talking about receivers... i now that the resonate oscilates at certain frequency and the antenna picks up the sine waves that are at the frequency... but how are they then turned into current...

what base-emitter voltage is needed for a current to flow through the trasnsistor?

Does an inverse exist for every quaternion under multiplication??

Roller coaster physic? what is the optimal angle for a banked curve on a roller coaster?
