While a linear force is a push or pull, a torque is a twist. Resonance- say an pendulum is swinging back and forth, the frequency of the pendulum swinging back and forth would be natural frequency. The prolongation of the synchronous vibration of the pendulum or a sound reflected off a surface is resonance. Overdamped, Underdamped- Backlash- the free clearance between the gears teeth, which is needed to prevent the binding of the gears if they are slightly not round Explosion-proof vs intrinsically safe wiring- explosion proof is equipment used to prevent high

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
