    Help me calculate a calculated bending stress (psi) in cantilever beam?

    Thank you! It makes sense now. The only weird thing is if I just 10^6 instead of 10*10^6, then it will be close to my theoretical value. But if I do 10*10^6, the calculated value is super off from the theoretical value.

    Help me calculate a calculated bending stress (psi) in cantilever beam?

    Homework Statement I am using a Vishay strain indicator with it hooked up to a strain gage hooked up 1" away from the wall on the solid beam. The beam is .5" by .5", and it is solid. The beam is 16" long and I am putting weights at the end of the beam. The weights are 1, 2, 5, 10, 15, and 20...

    What is the de Broglie wavelength of this electron?

    Homework Statement What is the de Broglie wavelength of this electron? Given is 500 eV Homework Equations KE= 1/2 mv^2 1 eV=1.602x19^-19 J The Attempt at a Solution I converted the 500 eV to 8.01x10^-17 via the given conversion. Now I'm stuck.
