The figure shows three uniform solid disks, each of mass 7.8 kg and radius 0.3 m rotating independently around a common axle. Two of the disks rotate in one direction at 5.3 rad/s while the other rotates in the opposite direction at 3.6 rad/s. Calculate the magnitude of the system's angular momentum about a point in the middle of the center disk. L= kg m²/s - Report your numerical answer below, assuming three significant figures. Remember to include a "-" when necessary.
A uniform thin rod of mass ?=3.47 kg pivots about an axis through its center and perpendicular to its length. Two small bodies, each of mass ?=0.277 kg, are attached to the ends of the rod. What must the length ? of the rod be so that the moment of inertia of the three-body system with respect to the described axis is ?=0.987 kg·m2 ?
Two uniform, solid spheres (one has a mass M and a radius R and the other has a mass M and a radius Rb=2R are connected by a thin, uniform rod of length L=2R and mass M. Note that the figure may not be to scale. Find an expression for the moment of inertia I about the axis through the center of the rod. Write the expression in terms of M, R, and a numerical factor in fraction form.

PLEASE DRAW AN FBD AND ANSWER IT ON A PAPER The figure shown is on a fixed frictionless axle. It has a moment of inertia of I = 50 kg-m2 . The forces acting on the object are F1 = 100 N, F2 = 200 N, and F3 = 250 N acting at different radii R1 =60 cm, R2 = 42 cm, and R3 = 28 cm. Determine the angular acceleration of the object.
Everyone's favorite flying sport disk can be approximated as the combination of a thin outer hoop and a uniform disk, both of diameter Da = 0.273 m. The mass of the hoop part is mh = : 0.120 kg and the mass of the disk part is md = 0.050 kg. Imagine making a boomerang that has the same total moment of inertia around its center as the sport disk. The boomerang is to be constructed in the shape of an "X," which can be approximated as two thin, uniform rods joined at their midpoints. If the total mass of the boomerang is to be m₁ = 0.235 kg, what must be the length Lы of the boomerang? | I Lb = = Cross-sectional view m
A cylinder of radius 1.84 cm1.84 cm and a spherical shell of radius 9.47 cm9.47 cm are rolling without slipping along the same floor. The two objects have the same mass. If they are to have the same total kinetic energy, what should the ratio of the cylinder's angular speed to the spherical shell's angular speed be?
Three small objects are located in the x-y plane as shown in the figure.

The objects are small in size, their moments of inertia about their own centers of mass are negligibly small.
Consider a person who is sitting on a frictionless rotating stool. The person initially has his arms outstretched and is rotating with an angular speed of 5.0 rad/s. He then pulls his arms close to his body, thus reducing his moment of inertia to 80% of the initial one. What is his final angular speed?

Total weight of a motorcycle and its rider is 215 Kg and their combined centre of gravity is 485 mm above the road surface when motorcycle is upright. Each wheel is of 550 mm diameter and has a moment of inertia of 0.9 kgm2 . The moment of inertia of the rotating parts of the engine is 0.12 kgm2 . The engine rotates at 3.5 times the speed of the vehicle and in the same sense. Determine the angle of heel necessary when motorcycle is taking a turn over a track of 30 m radius at a speed of 65 kilometre per hour.
At the moment of take-off, a diver's moment of inertia (I) was 50 kgm^2 and angular velocity about a mediolateral axis was 90 degrees/s. later in the dive, I (moment of inertia) changed to 15 kgm^2. What was the new angular velocity?
