Homework Statement
Given that I have a system with a rod of diameter 1 1/2 inches with a length of 17 in and a weight of 10 1/3 oz and a rod with a diameter of 3 inches with a length of 17 in and a weight of 20 2/3 oz. The two rods are butted together at one end almost looking like a bottle...
Given the picture in the attachment of two rods touching with them each being 17 inches long and one weighing double the weight of the other, would it make sense that the center of mass is 2/3 of the way down the picture from the thinner end? Or, am I going about this idea the wrong way?
So i calculated the center of mass to be 2/3 of the way up the "object" which would make it in the bigger rod? Would I be correct in assuming that? I am going off the fact that a uniform rod would have its center of mass directly in the middle.
Would that be the same for finding the moment of inertia for that system? just find the moment of inertia for each individual rod and average them together?
I am currently trying to find the center of mass of two rods. One rod is 20 2/3 oz and is 17 inches long with a diameter of 3. The other rod is 10 1/3 oz and 17 inches long with a diameter of 1 1/2 The bigger rod is touching the smaller one if they were both standing up. It looks almost like a...
Let's say I have a uniform rod lying on a table in a frictionless environment. Now I throw a ball with a certain velocity at one end of the bat. How can I describe the motion of that bat. I need to make it seem like it is going in a circle. I know it will move back and rotate but I don't know...
I understand that but the radius should be longer than the length of the bat because the bat is not pinned at one end. Therefore the center of the circle isn't at the end of the bat. I guess I am asking where is the center of the circle and how would I calculate that new radius.
I have a uniform rod laying on a table. A ball comes in and hits the rod making it move backwards but also rotating. Assuming that we are in a frictionless environment, how do describe the circle made by the rod?
It isn't from a question. I am conducting research on the sweet spot of a baseball bat. I am trying to determine angular momentum for the bat. I have taken the average bat speed of a college baseball player but I need to translate that into angular velocity.
How do you determine the angular momentum and linear momentum of a ball hitting a dowel rod lying on a table? The dowel rod is lying free on the table and the ball would hit it on the end. Is there a happy medium between angular momentum and linear momentum?
