A chandelier hangs from a chain in the middle of a dining room. Identify the forces on the chandelier.

Hey, everyone in this problem, a chair is suspended from the top of a stationary merry go round using a cable and were asked to list all forces acting on the chair. The options were given are a tension, stationary friction and gravity. B, gravity and centripetal see tension or de tension and gravity. Let's go ahead and get a free body diagram of the chair. So we can get an idea of what forces we have acting bigger chair. And we know that it's suspended using a cable. So we know that we're going to have a tension force from that cable acting upwards, keeping that chair suspended. The chair has some mass like anything with mass. We have that weight of the chair acting downwards care the force of gravity. And so in the downward direction, we have the force of gravity. What other forces do we need to consider while this is a merry go round. So you might think there could be some sort of centripetal force, but we're told that the merry go round is stationary, okay, it's not moving. So we have no centripetal force. We also have no friction. The chair is suspended from this cable. So the chair is not on the ground, it's not in contact with the surface. So we don't have to worry about friction. And so these two forces we've drawn the tension and the force of gravity are the only two we need to worry about. If we look at our answer choices, that's going to correspond with answer choice. D the forces acting on the chair, our attention and gravity. That's it for this one. Thanks everyone for watching. See you in the next video.
