So I have a question. I (moment of inertia) is basically mr^2 right? And r is supposed to be the distance from the axis of rotation. When the axis of rotation is directly through the center of mass, how is there Icm (moment of inertia about the center of mass). It's confusing to me, because so...

I wouldn't know what to call that force though... cause I feel it's a resultant force of the tension in the string. i wouldn't know what would cause the force other than from the result of other forces at work.

This part makes me confused. I think the acceleration would be zero because it's not moving, but that would make the sum of the forces equal to zero in both x and y, but there is a uncounted force against the wall, which I'm trying to solve for. hmmmm Am I adding in my equation the force...

thanks jackarms! I actually figured how to set it up right after i did this post. But now I'm stuck on this other part. Here's what i got. so sinθ = 15/50 (i got this by taking the radius of the circle as opposite and taking the length of the wire plus the radius) θ = 17.46 ∑Fx =...

Homework Statement A solid uniform 50kg ball of diameter 30cm is supported against a vertical frictionless wall using a thin 35cm wire of negligible mass (the wire is attached to the wall, the ball is attached to the wire and rests against the wall). Make a free body diagram for the ball and...
