Wow what a problem! Thank you so much for the help you guys! I did it all by hand and it was quite long but I was able to get the same b = s = m/3 = 12/3 = 4 and the base angles to be 120° which is essentially pi/3 because i used sin(θ-90) and cos(θ-90). Thanks again for the help, it was a...
so I don't have to use Lagrange multipliers. I can use the partials of f and substitute the constraint into each partial and then solve? Either way this seems to be a messy problem by hand with all the trig involved. This is a problem that my professor wants us to solve by hand not getting...
hmm So i have two ways of doing this problem? Using Lagrange's Method and not finding the critical points or using the constraint as a substitution in my equation immediately. Sorry a little hazy on this subject.
Homework Statement
An open gutter with cross section in the form of a trapezoid with equal base angles is to be made by bending up equal strips along both sides of a long piece of metal 12 inches wide. Find the base angles and the length of the sides for maximum carrying capacity.

Ok i think i got it. We want to create a cascade of electrons from anywhere in the tube. This means i can find the acceleration of the electron that's needed to accelerate it to the velocity needed to ionize a neon atom. And the least likely place of that to happen is at the cathode (furthest...
Homework Statement
Find the potential difference, capacitance of the Geiger Counter and the charge on the anode.
So, we have a Geiger Counter with low-pressurized neon inside. What we want is to have an alpha particle or electron to travel into the Geiger Counter with enough energy to collide...
Homework Statement
There is a region of space containing a uniform electric field of strength E. A neutral conducting cube with side length s is placed into this field. The cube is aligned with the field. You may assume that the electric field outside the cube is unaffected by any changes that...
