    Engineering Initially evacuated chamber and maximum theoretical work

    Thank you all for the help. The correct answer is in the attached file. That's the teacher's solution, so just plug and chug from there. My answer came out to be ##9.4367 𝑘𝐽##

    Thank you for your help, I'll have to swing by my teacher's office hours to check my work.

    Engineering Initially evacuated chamber and maximum theoretical work

    So change the upper bound of my integral to ##V_2 = 32## and use ##997 kPa## instead of ##896 kPa##

    I don't know how to use LaTex, so here's an attached file instead :) I hope that's right. I got a positive answer for W, which matches with W_out.

    Engineering Initially evacuated chamber and maximum theoretical work

    Given: V_1 = 10 L, V_2 = 22 L Not sure what I need to do here. We are told to ignore heat transfer, and the problem suggests that this is not a steady-state problem. The gage pressure is given, so I think that means we need to calculate for the absolute pressure, which would be 997 kPa. Cp and...

    Max Deflection Hand Calculations: Find 1.734in Plate Bending

    Summary: Max Deflection Hand Calculations I have to do a project that involves FEA on a thin plate in NX NASTRAN 11, finding the max deflection, and then proving that answer with hand calculations. The max deflection is 1.734 in. I have absolutely no idea how to do the hand calculations...
