Homework Statement [PLAIN]http://www.netbookolik.com/wp-content/uploads/2010/07/q.png Homework Equations The Attempt at a Solution

Hey there, For an Electrical Engineering candidate, will you suggest to learn C++. I am currently know Java and i am thinking about learning C++ by taking an elective course in my university. What do you think? Is it worth to take that course also can C++ help me in my career as an electrical...

Homework Statement What does f(x, y) function mean? Or What does f(x, y, z) function mean? Although, f(x, y) mean 3-dimensional, what is the matter with f(x, y, z)? This is a general question, i am asking this question to really get the idea. Can anyone help me to figure out it...

f(x, y, z) = 0 f(x, y, z) = ... Homework Statement [PLAIN]http://www.netbookolik.com/wp-content/uploads/2010/07/q12.png Homework Equations The Attempt at a Solution Sorry have no idea:(

Homework Statement [PLAIN]http://www.netbookolik.com/wp-content/uploads/2010/07/q1.png Homework Equations The Attempt at a Solution I thought, in order to take derivative function must be cont. so it would be nice to check limf as (x,y) goes to (0, 0) but it did not seem to...

Oh, i see now, i made a dummy mistake. Thank you for your quick reply!

f(x, y, z) ? Hey there, Sorry for the title, but i cannot find any appropriate one for it, here is my question! If f(x, y, z) = tanh (x+2y+3z) => fx =?(what is the derivative of f(x, y, z) with respect to x?) Actually, i know the answer but i do not get the idea! In case it might...

But again i cannot get the result that is given by book. So do i have to take perpendicular distance to the corner for the each rod? I mean for example; for top two rods it is easy: I = (1/12)ML^2 + M(L/2)^2 but when it comes to bottom rods, it is being complicated, unfortunately. Again what...

Does it make sense firstly finding all of four rods moment of inertia at its centre then taking it and finding the new moment of inertia secondly at the corner of square? Actually i cannot understand precisely, can you please be more clear?

Homework Statement When we put together 4 rod in case they will construct a square and when we hang it from the corner. How can we find its total moment of inertia? Length of rods: L Mass of rods: M Homework Equations Paralel Axis Theorem: I = I + Md^2 The Attempt at a...

Angular Accelaration = Angular Velocity^2 ? Homework Statement Can we always says angular accelaration is equal to angular velocity^2? My friend said that i was wrong when think like that to solve question? Homework Equations Accelaration = -(angular velocity)^2 X Radius Acceleration...

Hi All, I have a mechanics final soon, therefore i am looking for good source where i can find exercise for the exam. Also it would be beneficial for the others looking for the same thing in the future. Thanks in advance.

Hi there, As we know gravitational potential energy is U = -GMm/R right? Here is what i obsessed, in case for the each particle can we say half of this energy belongs to one particle? I hope my question is clear enough:) Thanks in advance.

Actually, moment is the effect of forces to make things move or revolve; therefore we multiply them with R.

mV^2/R = ma => a= V^2/R This is basically centripetal acceleration, in case if you are really asking this.
