Did I ask the question wrong? Sorry y'all I'm trying... :frown:

So I think I've got this, would anyone mind helping me check my work (@DEvens :nb))? I might be totally going about this wrong Assume the following values: T = 0.1 sec circleRadius = 50 circleOrigin = (0, 0) armLength = 40 armPos = (10, 0) //the point the arm is rotating around hingeLength =...

Ah and actually then wouldn't the centripetal acceleration just be the line from the weight to the rotation point (because of vector addition)? Like the hypotenuse not drawn in the triangle above (rotation point, hinge point, weight point). If I break that vector into x and y components can I...

Thanks @DEvens . It's rotating in the vertical plane and I think safe to assume in a vacuum so gravity can be ignored. I may be horribly mistaken, and please help correct me, but I think then the forces acting on the weight are from the hinge pulling on it towards the hinge's rotation point...

Homework Statement I have a an arm with an attached hinge and weight that is rotating inside of a circle, but important the arm is not rotating about the center of the circle. The arm is spinning fast enough so that the weight is always making contact with the edge of the circle. I need to...
