    PSpice - Combined power dissipated by selected resistors?

    Very, VERY new to PSpice, and using PSpice for TI. I've got a resistor network set up with a voltage source, and my simulations are working properly. Is there any way to set up an output that adds together the power dissipated by resistors named R1, R2, and R5, for example? I've got 30+...

    Torsion Spring Loading Direction

    Hello all, Can anyone tell me why torsion springs are always installed such that the applied load closes the coil, rather than opens the coil? Phrased differently: what would be the danger in designing a spring that opposes a force in the "unwinding" direction? Thanks in advance. Nate

    Flange Nut With Flat Washer

    Is there any reason why a joint would contain a flat washer under the flange head of a flange nut? Extra info: I'm looking at a joint that holds a hardened steel disk to a hub (4 joints per disk/hub). The joint in question has a carriage bolt on the hub side of the disk (carriage head in the...
