I'm having some problems doing my homework. Please help me. 1. Three rods, each of length L and mass M, are welded together perpendicularly (like an x-y-z coordinate system). The axis of rotation is drawn in pink in the image below. I have to find the moment of inertia. I used the...

I see what your saying now. Thanks, I'll grind through this problem later tonight.

Since it's a horizontal curve, the weight, down, should be balanced by a frictional force, up. I think that's how it works in a certain amusement park ride whose name escapes me at the moment.

If you wouldn't mind helping me again, I have another question that I'm stumped on. A plumb bob does not hang exactly along a line directed to the center of the Earth because of the Earth's rotation. How much does the plumb bob deviate from a radial line @ 35 degrees north latitude? Assume...

So I would do the second part of the problem focusing around the head? Gotcha. It'd be T=mv²/r, using the mass of her head I think. Thanks for responding.

A child is lying on her back. The tension in the muscles of her neck is 55N as she raises her head to look past her toes and out the motel window. Ten minutes later she is screaming and sliding feet first down a water slide at a constant speed of 5.7 m/s in a horizontal curve of radius 2.40 m...
