Project for mechanical design. I was stuck and not sure how I should take on the problem so was looking for some pointers.

Thanks for reply Billy, yes I plan on assuming the torque and speed values I'm given is constant. I've outlined the steps I'll take to solve this problem and my final step I expect to be able to know the angular velocity of gears A1 and B1 that will allow me to know the torque and velocity of...

< Mentor Note -- thread moved to HH from the technical engineering forums, so no HH Template is shown > I have a design problem that has two predictions that I must make. The constants that I am given is the amount of teeth each gear has, the diameter of the gears, the input torque, speed in...

Okay thanks I got it

Ok then that would mean dE/dr wouldn't work so, it has to be dE/dt in order to get my answer; so in order to take the derivative with respect to time I would have to plug in v=d/t into the equation right...

That is what I show up there its E=-\mu/2r where \mu = (v^2)r

So if I take the derivative of the specific total energy E with respect to the distance value r something like this: dE/dr = -\mu/2r --> i plug in the value of \mu = (v^2)*r it turns into -(v^2)*r/2r the r will cancel in this case...(or maybe i should leave one alone and continue to eval the...

1. {This paradox denotes the fact that a satellite in a near circular orbit suffers an increase in velocity when subject to a drag force.} The Specific energy of the satellite is K + U = E where K =v^2/2 is specific kinetic energy. U= -u/r is specific energy and E is specific total energy. If...

Okay, I think I'm heading in the right direction now, I am trying to evaluate the radius of curvature as a function of position from there i will attempt to...not sure yet

Homework Statement A projectile in uniform gravitational field g=-g*j\hat{} with initial location x(t=0)=_{}xo, y(0)=_{}yo show explicitly that the minimum value of radius of curvature \partial of the resulting parabolic trajectory occurs at the apex and equal to (^{}vox)^2/g Homework...
