I'm looking for a way to rotate blocks. There is a single axle going through the blocks.. say there are a dozen of them. I am trying to figure out a way to rotate each block individually to one of the 4 sides based on different inputs. I am also trying to accomplish this with a single motor...
Homework Statement
A particle moves with constant speed in a circle with a radius of 5m in a counter-clockwise direction. It makes 1 revolution every 16 seconds.
What is the average velocity for 1/4 revolution? 5/4 revolutions?
Homework Equations
Wrapping Function: W = (cos t, sin t)...
Homework Statement
Find the derivative of the function f(x) = sqrt(x).
(Bear in mind that cannot use the power rule or anything like it. I must use limh->0.)
Homework Equations
limh->0 (f(x+h) - f(x))/h
The Attempt at a Solution
I'm getting hung up on expanding out the...
Well the range of 25 + (x - 3)2 is y >= 25, right? So, the range of sqrt(25 + (x - 3)2 is y >= 5?
Yea, I think expanding the (x - 3)2 term messed me up. I was thinking that i was possible for the radicand to be a negative number.. ugh. Stupid mistake.
Thanks a lot for the help.
Homework Statement
Find the range of h
Homework Equations
h(x) = sqrt(25 + (x - 3)2)
The Attempt at a Solution
I factored out the (x-3)2 and simplified to get
sqrt(x2 - 6x + 34)
I was trying to figure out the domain first, knowing that x2 - 6x >= -34 in order for the...
This is the one occupation that I'm sure I would love, but the more I read on it, the more impossible it seems that I will land a tenured university position.
I'm a 1st year student at Michigan State and have a 3.9 at the moment. I imagine I'll end up in the 3.75+ area after my physics...

if you look at my scope, you'll probably notice that when extended, the actual "tube" part isn't near the middle of the scope.. if I mounted it with an eq, i don't think the fulcrum would be centered. i think i'd have the same...
Is there an guide on what parts to get/how to assemble one anywhere? Sounds like a useful investment.. it'd just be nice to see how other people have done it before I go blow $40 at home depot.
Yea last night I was pretty desperate and strapped a 5lb. dumbbell on it with my belt. It was good when I looked at things near the horizon.. but when I had to aim up, it was too heavy and kept drifting up. Are counter-weights a regular part of viewing with a dob for everyone else? If so...
..sucks. I have the Sky-Watcher 10" dob (got it for xmas). All around, it's a great scope for the cost, and produces some very crisp visuals of surprisingly distant objects... when it can center on them. I find myself having to constantly aim higher than the object so my telescope will "fall"...
