    How to carry units in integration

    Homework Statement I am trying to integrate from 0 to 10 ft -4x^2/2+4x. I am solving for deflection. The forces are in kips. Somehow the book ends up with k-ft^3. I don't understand how I would carry units in an integration. Any help please? Homework Equations The Attempt at a...

    Engineering Need to interview a Civil Engineer

    Thank you so much for responding. I erased question 10, but it was basically how many specializations are there is civil engineering. @bklynkenny you said you don't work as an engineer. Is that because you have an MBA now and work as a manager? I am really interested in management.

    Dispersion by diffraction grating

    That's the equation I'm used to. If we assume that the angle is small then sintheta=y/L dsintheta=m*wavelength d(y/L)=m*wavelength m*wavelength*L/(d)=y ? I don't know what's wrong with the equation. For the units I coverted everything to cm because 1/7300=d in cm.

    Induced emf at a specific time

    I plugged in -36.12 but it's still wrong. Can we have a negative voltage?
