I would like to practice logic thinking more. The sort of problems I'm talking about are like this: Define two constraints, which relates the variables x and y to v such that if either x or y is 1 then v is forced to be 1. Where the answer is then: x ≤ v y ≤ v Does anybody know where I can...

Yeah but what if you suddenly get bad at playing Smash Bros. and no longer cna win tournament prizes, then you have no income and no education to rely on? Wouldn't it be more wise for girls to choose a guy that has a steady income? A guy who is actually smart?

My mom always used to tell me that girls are attracted to guys with a good education but now I'm thinking it was something she just told to get me to study. I've noticed that I have no more luck with girls than my friends who don't have an education past high school and that in many cases, guys...

Are you sure? I've tried searching for it many places but I just can't find anything about it.

Can anyone explain to me why a bimorph has a metal in between the two piezo-layers?

Does the mass flow rate differ depending on whether it's after the feedwater heaters or before the turbines or is it just constant throughout the entire system?

Oh, I see. Actually when I looked at my notes I found a place where it says the change in pressure is zero. It's just a lot of information to keep up with. Thanks! :)

What I'm asking for is if there is a guide for the properties of processes like isochoric, isobaric, isothermal and adiabatic. For instance, a comprehensive guide that tells me that the pressure in an isobaric expansion is the same before and after, etc. If there isn't, does anybody have any...

Thank you!

Ahh, I mixed them up. Ok I changed the drawing so now d is the distance the mass moves up and x is the distance the roller moves down: So I have: h' = x * sin(theta) And: h = d * sin(beta) And... I know that the distance that both the mass and roller travels are equal to each other: x = d...

Alright let me see... I drew this line in the drawing: The number "2" on the left indicates the final position where the cylinder is when the box is at the top. If we assume that "d" is the distance down the triangle that the cylinder rolls and if h' is the height of the potential energy for...

Homework Statement A cylinder with mass M and radius R and moment of inertia I is standing on a rough surface (the left part of the triangle). A box with mass m is standing on a smooth surface (right part of the triangle). The cylinger and box is connected by a massless rope over a massless...

Oh I see. If the situation was where the wheel was standing at rest and didn't move then the friction force would be to the right to prevent it from rolling but since the wheel is rolling that means our friction force is to the left, correct?

Homework Statement The following wheel consists of an outer ring (R) and an inner ring (r). The wheel moves clockwise by a force F applied to the inner ring as shown in the picture to make the wheel roll. Draw the friction force. Homework Equations Nothing The Attempt at a Solution I could...

Homework Statement Suppose an oxygen molecule traveling at the speed of 484 m/s bounces back and forth between opposite sides of a cubical vessel 0.1 m on a side. What is the average force the molecule exerts on one of the walls of the container? Homework Equations F=p/t The Attempt at a...
