1 watt equals 1 Newton metre 1 kg equals 9.81 Newton metres 2.5 kg = 24.525 Nm = 24.525 Watts of mechanical energy.

Hi PF! Do you know which bibliography style Journal of Engineering Math is? One example is attached. The template they provide for publishing does not specify, and the editor said to consult previous publications. After googling for an hour, I don't know where to turn. I could always email an...

A reservoir supply tunnel transfers water from a high level storage reservoir via a 200mm diameter pipe to a lower intermediate reservoir. The total height difference between the free surfaces of each reservoir is 76 m. The pipe is 700 m long and the coefficient of friction, Cf is 0.009. The...

Not homework question, just need clarification and explanation. How did the person get from the left equation to the right side. I know he's just simplifying. But he didn't include steps and I've been trying to work out how to no avail. Any help on how this person simplified the LHS to RHS? Thanks!

What really is the difference between a book for Engineering Math and a Math methods book for, say, Physics? They all look very similar to me. Also, a math method book may significantly differ from another math method book depending on the level covered and a math method book may be very similar...

I am trying to work my way through Stephen Pope's "Turbulent Flows". I'm finding that my Achilles heel (as has been throughout my undergraduate degree) is maths. Since this book is essentially applied maths, I'm finding it difficult. So I'd like to simultaneously work through a course in...

Hi, I'm currently studying to become a chemical engineer. After learning differential equation and linear algebra, I've realized how useful they are in my engineering courses since they make setting up equations and solving them so much easier. So I was wondering if there are other math that...

What are some standard math courses that nuclear engineers take in college? Do they do more math than calculus 2? Do they use a lot of geometry? What are some standard math books that they will read during their math studies? In general I am referring to the nuclear engineers that work in the...

Why does it have to be so rigorous when it comes to proving things that are so obvious they (seemingly to me) don't need to be proven? I just started on my engineering degree, and I am extremely surprised at how proof-based the math is in my country. Why can't it be more intuition based? For...

Homework Statement Solve the differential equation y(iv)(t) - 16y(t) = 30sint subject to y(0) = 0, y'(0) = 2, y"(∏) = 0, y'"(∏) = -18 Homework Equations There is a Laplace transform table attached if needed :) The Attempt at a Solution I tried making it homogeneous and then...

Homework Statement Solve the system of differential equations: y'(t) + z(t) = t y"(t) - z(t) = e-t Subject to y(0) = 3, y'(0) = -2, and z(0) = 0 Homework Equations My professor did an example in class that was much simpler and solved it using Kramer's rule. The Attempt at a...

Homework Statement Solve the difference equation: an+2 - 5an+1 + 6an = 4n Subject to a0 = 0 & a1 = 1 Homework Equations an = Arn The Attempt at a Solution I got two solutions for the first part for when it is homogeneous by substituting an = Arn into the equation and solving for...

Homework Statement \int y'(u)y(t-u)du = 24t3 The integral goes from t (top) to 0 (bottom) With y(0) = 0 Homework Equations I want to say it kind of looks like a convolution problem \int f(u)g(t-u)du The integral goes from t (top) to 0 (bottom) The Attempt at a Solution I have no idea...

Homework Statement Evaluate the following in x+iy form. i3+i Homework Equations i=rei\Theta The Attempt at a Solution i=rei\frac{pi}{2} i3+i = i3*ii (-i)(ei2\frac{pi}{2}) =-ie-\frac{pi}{2} =-.2079i I understand how it all works out except \frac{pi}{2}. I can't figure out how...

I have used Thomas' Calculus , now what should I consider next (mainly for Differential Equations/Complex Analysis/Fourier Transforms etc.) I heard Kreyzig is good , any recommendations on that ? PS: Actually I found Thomas' to be very good, but when I read Courant's Calculus text, I felt as...

Hello everyone, This is my first post. My problem is that I'm getting terribly frustrated trying to decide which degree to pursue? Everyday I change between electrical engineering, math, or physics. I have been back in school since spring '08. And my original intention was to pursue a...

In many of the topics in math i hav learned so far, i just found that engin textbooks such as <advanced engin math> are much more understandable and yet covering similar depth of contents than mathematic methods book such as aftken&weber which my teacher choose as reference book for e course. I...
