New Question So in planetary motion, if satellites travel faster at the perigee than the apogee, that implies some change in velocity. Is it the tangential velocity that is changing, or the angular velocity? If universal gravitation is the only force acting between the two objects, how can the...

When deriving the motions of the planets in our solar system, do we typically ignore Newton's law of gravitation between the planets themselves, since the force is negligible?

I guess I'm not so much interested in the derivation, just a source of where you got the equations from, unless you pulled them off the top of your head. Do you know the equation for delta_max as a function of x? I mostly need to the know the deflection at the midpoint...I should've stated...

So the maximum deflection (delta_max = {F*(L^3)/[12*E*(I1^2 + I2^2 + 14*I1*I2)]}*[(I1 + 3*I2)^3]/[(I1 + 7*I2)^2]) occurs at the center of the beam as well, or not neccessariy? And do you have a reference for this equation or a derivation?

No suggestions? Are there any superposition principles I can use for this problem?

Hello, I am doing a problem for work where I use a deflected beam as a model. Basically, I am using a beam with two fixed ends and a force directly in the middle. The deflection equation for this model is: delta_max=FL^3/(192EI) This assumes I is constant through the entire beam...

No, ignoring complications like that. With ri= mean distance from Earth to the sun.

I first want to say that this isn't a problem from school or anything, I just thought of it one day and when I tried to do it, I couldn't! Homework Statement If the Earth suddenly stopped orbiting the sun in its circular path, it would immediately begin the accelerate toward the sun in a...
