What I am trying to do is play with the balance of moving the center of gravity away from the rotational axis. The tradeoff is as you narrow the piece up the CM goes out, which increases your R. Problem is mass goes down at the same time, unless you stack or thicken it as you mention. The...
Hello, I am trying to make something that spins out of balance. currently my current weighs are half circle in shape. I know that if I change the profile of the weights to a pie shape (less than 180deg semi circle) the center of mass moves away from the axis of rotation, but at the same time...
Thanks for the quick responce. What was confusing me was that the half disk is rotating around what is the center (not COG) I thought it might get more complicated due to the rotation not being through the COG. thanks just 1/2 the formula for a full disk because it is half the mass. Here is...
Hello, just found this forum didn't know it existed. hopefully someone can help with this.
I am trying to figure out the mass moment of inertia for a half disk spining around the center axis. A full disk is I=1/2*M*R^2. Would the inertia for spining a half disk around the center axis just...
