1. ### 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...

Thank You!
3. ### Engineering Need to interview a Civil Engineer

If you don't mind answering this question, would you say the salary is better as a construction manager or about the same? Can all Civil engineers work as a construction manager?
4. ### 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.
5. ### Engineering Need to interview a Civil Engineer

Is it hard to find a job now as a Civil Engineering graduate? I am in the US.

1. What made you choose this type of engineering? 2. What type of equipment do you work with on a day to day basis? 3. What is your educational back ground? 4. What is your favorite part of the job? 5. What is you least favorite part of the job? 6. Do you need a...

8. ### 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.
9. ### Dispersion by diffraction grating

Homework Statement White light containing wavelengths from 396 nm to 756 nm falls on a grating with 7300 lines/cm. How wide is the first-order spectrum on a screen 2.15 m away? Homework Equations y=m*L*wavelenth/(d) The Attempt at a Solution using the equation I have found y1 to...
10. ### Induced emf at a specific time

Thank you very much I appreciate it.
11. ### Induced emf at a specific time

Could you please tell me where I'm wrong? I have a couple of hours left.
12. ### Induced emf at a specific time

I plugged in -36.12 but it's still wrong. Can we have a negative voltage?
13. ### Induced emf at a specific time

Homework Statement A circular coil with 35 turns of wire and a diameter of 19 cm is placed in a magnetic field given by B(t) = 6 t^2 + 6 t + 2 T where t is time in seconds. The field is perpendicular to the plane of the coil. What is the induced EMF at t = 5 s? Homework Equations...
14. ### Time required to charge a capacitor

Homework Statement A capacitor with a capacitance of C = 28.7 μF is slowly charged by a constant current of I = 63.2 nA. How long does it take to charge the capacitor to a voltage of V = 28.9 V? Homework Equations q=cvb(1-e^(-t/RC)) Vb=IR+QC The Attempt at a Solution I have tried...
