Consider the plane wall of Figure 3.1, separating hot and cold fluids at temperatures \(\displaystyle T_{\infty,1}\) and \(\displaystyle T_{\infty,2}\), respectively. Using surface energy balances as boundary conditions at \(\displaystyle x = 0\) and \(\displaystyle x = L\) (see Equation 2.34), obtain the temperature distribution within the wall and the heat flux in terms of \(\displaystyle T_{\infty,1}\), \(\displaystyle T_{\infty,2}\), \(\displaystyle h_1\), \(\displaystyle h_2\), \(\displaystyle k\), and \(\displaystyle L\).

i know the two of the formulas, but i can't find...

this not book question. i just want to know the difference of constant and nonconstant acceleration

i'm certain the 3 formulas can't be used this time

\(\displaystyle v = v_0 + at\)

\(\displaystyle x = x_0 + v_0t + 0.5at^2\)

\(\displaystyle v^2 = v_0^2 + 2ax - 2ax_0\)

how to solve this question...

Have i missed something? Can anyone picture the polygon?]]>

this new one please solve it

I am a graduated structural engineer and I am going through a book that has section on approximate methods for calculating rotations, displacements and moments etc for rigid frames. I have come to an equation in the book that I am finding difficult to solve. The book gives this equation (2.23) in two forms which are below:

And

I want to solve for the rotation at the joints "theta". Where theta

I know how to solve this problem from scratch, but I don't know how to solve it by d'Alembert's solution.

The d'Alembert's solution is:

The d'Alembert's solution is:

Diagonals AC and BD intersect at point P and create similar triangles

АВР ~ ACP with ratio 2: 3 (i.e AB : CD is 2:3).

Point A is at (-6, -8), point C is at (9, 12), and point B is in quadrant II.

Find the intersection point P of the diagonals.]]>

Point P has coordinates (0, -3)

Let A with coordinates (a, b), be a point on circle O so that AP is tangent to the circle.

- Find coordinates (a, b) for such a point A.
- Remember to notate your work and indicate how you are applying any relevant definitions or theorems.

The standard way of doing it would be using the discriminant. So the equation of the line is y=m(x-5) and substituting this into the circle equation:

This needs tidying up:

And then using the discriminant, but the...

Find the domain of f(x) = (x^2 - x - 6) / x - 5. there is no tap to write the square root so i write brackets (x^2 - x - 6).

it is clear 5 is the domain of the function. it keeps telling me wrong. i know 5 - 5 = 0 this is invalid in the fraction when it is written down.

there is no tap for infinite, so i write the domain (-infinite, 5) U (5, infinite). it says this is a wrong answer.]]>

Thanks in advance for your help. The original question is as follows:

My first question is about the part that says, "parallelogram with side lengths of a and b." I always thought the side lengths (the sides opposite each other) would be equal in a parallelogram. I am confused about what I am missing here.

As for the trapezoid, I read in someone else's reply that if I draw a line from Y in the upper right corner to point P on the base, I will get a parallelogram on...
