Physics 12u - Two masses Spinning on a disc - Math Help Boards.

Let I 2 be the MI of the disc and the blob. Question 2. A horizontal disc is rotating about a transverse axis through its centre at 100 rpm. A 20 gram blob of wax falls on the disc and sticks to it at 5 cm from its axis. The moment of inertia of the disc about its axis passing through its centre is 2 × 10-4 kg.m 2. Calculate the new frequency. Bob S. 4,662. 6. The really interesting theoretical spinning-magnet problem is a strong solenoid magnet spinning about an axis that is perpendicular to the axis of the solenoid at a speed such that the solenoid field at a large radial distance sweeps azimuthally at a relativistic speed. Would this alter the magnetic field? Bob S.

Conceptual question Mud on a spinning tire will probably fly off.

The Physics of the Force on Spinning Baseballs. The origin of the phrase "spin doctor" is somewhat dubious. Most agree it was first in print as part of a New York Times editorial in 1984 describing the postmortems of the debate between Ronald Reagan and Walter Mondale. Some argue spin doctor is derived from the expression "to spin a yarn.". Answer (1 of 3): A2A: Does a spinning disc have less air drag than a stationary disc in an aerodynamic test? I don't know with any certainty. I assume you mean the disc is perpendicular to the flow and the direction of spinning is about its axis of symmetry. If you meant some different arrangem.

Centripetal force is not an applied force. If a body is moving in an arc, there must be a force acting on it to achieve that. If you add up all the forces acting on the body, and take the component of that which is orthogonal to the current velocity, that is the centripetal force.

What is a physics behind spinning of a top? - Quora.

Conservation of Angular Momentum means that the man turns in the opposite direction from the spinning bicycle wheel. The Details: This illustrates an important conservation law of physics: the conservation of angular momentum or turning motion. Anything that is turning has angular momentum. This is similar to inertia, only in rotational motion.

Nov 11, 2018 · Mar 5, 2012. 9,802. Wild ownz al said: A penny of mass 3.10 g rests on a small 20.0-g block supported by a spinning disk. If the coefficient of friction between block and disk are 0.750 (static) and 0.640 (kinetic) while those for the penny and. block are 0.450 (kinetic) and 0.520 (static), what is the maximum rate of rotation (in revolutions. Punch a hole wherever there's a black dot on the pattern. Mount the disk to the fan. Try to center it the best you can (the cross on the disk represents the center). One way to do this is to tape the disk to the fan blades. On most safety fans, the fan blades are attached to a removable holder. Inspired by a popular physics question, I animated a disk which drops onto another spinning disk. The two adjust until they ave the same speed.

11.3 Conservation of Angular Momentum – University Physics.

A spinning solid disk, rotating with angular velocity Wo, is put down on a level surface. It slides and rolls until it reaches an angular velocity W at which it rolls without sliding. Show that W = Wo/3 I place my origin on the ground so that angular momentum is conserved. The disk spins clockwise 1 = right when the disk is placed on the floor. Detailed explanation of the disc reading process: When I push both handles to trigger the disc reading process the laser unit moves to the inside of the disc, goes a bit off and enables the CD laser for a short moment and then switches to the DVD laser for ~1 sec. After that the laser unit stays in position and doesn't move. The disc is not.

Question: 1 point A disc spinning with a constant angular velocity when a a piece of clay drops onto it and sticks to the disc. Which of the following statements is true about what happens to the clay-disc system? The kinetic energy decreases O The angular velocity decreases The total angular momentum remains constant All of the above. Solution Formula of angular momentum L = I ω. L = angular momentum (kg m2/s), I = moment of inertia (kg m2), ω = angular speed (rad/s) The angular momentum L = I ω = (2) (1) = 2 kg m2/s. Read Capacitors in series and parallel – problems and solutions. 2. A 2-kg cylinder pulley with radius of 0.1 m rotates at a constant angular. 11. (a) 17,500 rpm (b) This angular velocity is very high for a disk of this size and mass. The radial acceleration at the edge of the disk is > 50,000 gs. (c) Flywheel mass and radius should both be much greater, allowing for a lower spin rate (angular velocity).

A bit of mud stuck to a bicycle’s front wheel of radius r detaches and is flung horizontally forward when it is at the top of the wheel. asked Aug 7, 2019 in Physics by Satkriti ( 69.3k points) rotational mechanics. P is the force which the lady (that's you!) pushes to keep the wheelchair moving with a constant speed. All forces must add up to zero; we achieve this summing separately x and y forces: N-Wy =0= N-W cos θ or N=W cos θ, and. P-Wx-f =0= P-W sin θ-Wμ cos θ, or P = W (sin θ+μ cos θ ). Now I can answer your questions. So for anyone who encounter the same problem of the PS3 not spinning the discs I can only suggest that you replace the lens or the entire laser assembly. Like I said I only got myself a new lens and it works fine together with the old spindle motor. Thanks to the people who replied and came with suggestions.

Bullet hits a disc | Physics Forums.

The bullet could compress and deflect off. The bullet could stick to the disc. Since the question does not give you the final speed of the bullet, lets assume that it sticks to the disc. In this case, the question is asking for the velocity of the centre of mass of the disc + bullet and this is just a matter of applying conservation of linear. A horizontal disk of rotational inertia 4.25 kg.m^2, with respect to its axis of symmetry, is spinning counterclockwise about its axis of symmetry, as viewed from above, at 15.5 revolutions per sec.

Nov 23, 1998 · Test 3 Problem 4. a) This is just like problem 10-49, except this time the child starts at the outside and walks inward instead of vice-versa. Apply conservation of angular momentum (there are no net external torques on the system of merry-go-round and child). Thus we have. Suppose we have a disc of radius R suspended vertically from a pivot on its edge. This disc is then given an initial angular displacement θ and permitted to freely swing without friction.
