So for part (b), we have \text{norm}(\nabla g(x_{Q},y_{Q},z_{Q})) = \nabla g(x_{Q},y_{Q},z_{Q}) \cdot \frac{1}{\sqrt{3}}\left(1,-1,-1\right) This seems so tedious to solve though. It's on a practice exam my teacher gave us and his tests are very reasonable given the time limits, so I'm...

Homework Statement See attachment. 2. Homework Equations /solution attempt Part (a) Well, the gradient evaluated at (1,2-1) will give the rate of change. If we want the maximum rate of change then we need the directional direction such that the unit vector \mathbf{u} is in the same...

Say we have a rectangular object A accelerating with some acceleration a across a rough horizontal surface. Object B starts with velocity v on the top left corner and slides across the top of A subject to a friction force. Now if we consider object A by itself, it is subject to a friction...

OH. I completely forgot my rules. The curl of a gradient is a the zero vector and the divergence of the curl is the scalar 0. Thanks. Also, for the very last integral, does that not not exist because d\bold{s} denotes a line integral, but since there are two integral symbols, it doesn't mean...

It's just called "Fluid Mechanics." https://www.amazon.com/dp/0073309206/?tag=pfamazon01-20

I'm a mechanical engineering major and the course is really an intro to fluid mechanics, but it's designed for mechanic engineers and I've heard it's pretty math intensive. The short description is: "Fundamental concepts; hydrostatics; integral and differential equations of fluid flows...

So I'm most likely studying abroad next semester and taking a Fluid Mechanics course. At my home university, the pre-reqs are multivariable calc, diff eq, statics and dynamics, and classical thermodynamics. Abroad, all I need are multivariable and diff eq. But I'm worried that I might be at a...

Homework Statement The position of a particle on the x-axis is given by x = 2t^2, due to an applied force of F = e^(2t) parallel to the x axis. a. Write an expression for the power supplied by this force as a function of time. b. Compute the instantaneous power when the particle is at x =...

Please, I've got a recitation in front of the class tomorrow on this problem. Any help would be greatly appreciated

Urgent help on static force at the top of an incline DUE TOMORROW Homework Statement A 5.0 kg block on an inclined plane (angle 37 degrees) is acted on by a horizontal force F with magnitude 50 N. The coefficient of kinetic friction between block and plane is 0.30. The coefficient of static...
