I passed my statics course and am currently taking material stength course. The thing that has been on my head is the fact that, although I know how to do shear and bending moment diagrams... I do not know how to READ them. In other words, the diagrams don't mean anything to me. For...

Thank you very much. So, just to be clear, if we were given the potential difference V and charge Q of Capacitor C, then based on that equation we may find C with C=Q/V? Or does that contradict the fact that C is determined by geometry only?

Hello, I have a question regarding the equation q=CV, where q is the charge and V is the potential difference of a capacitor, and C is the proportionately constant C of the capacitor. From what I understand, the value of C depends only on the geometry of the plates and NOT on their charge or...

Thank you. It's making a little more sense. I have always found the 'prime' notation to be much easier to interpret, but I guess with physics and differential equations the leibniz notation is just more specific. For Math problems, if we were to see something as (dy/dx)(x+y)=(some constant)...

I have a question I should have asked a LONG time ago. When we see this notation being used in such formulas as i=dq/dt (definition of current) or dy/dx (etc, etc), are we saying (in the case of current) that current is equal to the change in charge with respect to time? Or is it the "current...

I apologize for not using the template, but my question is more of a conceptual question than anything else. The only thing so far that confuses me with Shear and Bending Moment Diagrams is when, in some cases, it is easier to approach the beam from the right side instead of the left...

I have a conceptual problem regarding the following scenario: Try to imagine a triangle with two blocks on each side, attached together with a rope, and a pulley at the tip of the triangle. Block A & B are attached to each other through a rope. Blocks A & B are in static equilibrium, each on...

Thank you. The only thing I had to change was the limit of 16 to -9 to 3 to -1 and got the answer correct with the same approach as above. You are correct about the fact that I drew the D region incorrectly... stupid mistake on my part.

Homework Statement Let D be the region in the x,y-plane enclosed by the curves x = (y^2) - 9 and x = 2y - 6. Find the volume of the solid with base D that lies under the surface z = 1y^2. Homework Equations Fubini's Theorem and Fundamental Theorem of Calculus The Attempt at a Solution...

I found out what my problem was. I made the stupid mistake of differentiating u^-2 when I should have integrated. Thank you. Your first integration was correct, and that was what was causing my mistake.

When solving for reactions in a 2D diagram as seen below, how does each type of joint affect the summation of forces in the x & y components? My problem asks to find the summation of forces in the x & y components, and has a smooth pin connection in the left of the beam and roller on the right...
