SECW OM
A motorbike wheel with an 8 kg mass has a 0.4 m radius of gyration around the z-axis, as shown in
Figure. The wheel's shaft is supported by bearings A and B and rotates at a constant rate of 150 rpm
in a counter-clockwise direction from the z-axis, while the frame rotates at 12 rpm in a counter-
clockwise direction from the y-axis. Determine the resultant reaction forces at each bearing A and B
due to the mass and gyroscopic effects. With the result of forces, which bearing has a tendency to
fail first, which bearing should be considered for design purposes and explain the effect on motor if
the bearing fail.

Problem 2: A car is pushing a barrel to the right. The pushing force P is applied by the front bumper which is level with the center G of the barrel (see figure). The barrel has mass m, radius R, and radius of gyration kG. The coefficients of static and kinetic friction between the bumper and the barrel are µs and µk. The coefficients of static and kinetic friction between the barrel and the road are also µs and µk. 1) If the barrel doesn't slip on the road, find the acceleration of the barrel and the minimum value of us required to ensure no slipping. 2) If the barrel slips on the road, find the acceleration of G and the angular acceleration of the barrel.

In the figure below, the disc has mass m = 82.2998 kg, radius r= 6.7128 m, and moment of inertia about the mass centre l= mr2/2, and is attached to a block of mass M= 153.7102 kg which rolls across the surface. The block is supported with a spring with stiffness K = 630589.8842 N/m. If the disc rolls without slip and the block moves without friction, determine the natural frequency of the system.

A wheel is attached by a cable to a block The wheel has a radius of 2ft and weighs 300lbs, the block weights 20lbs. If the radius of gyration about the point of rotation of the disk is 1.5ft, how many revolutions will it take for the wheel to come to a stop assuming it was moving at 10 rad/s CW. Assume the block is on the left side of the wheel and thus causes a CCW moment.

At the moment shown the rod has a counterclockwise angular velocity of 3.00 rad/sec, and the spring is compressed by 2.00 ft. Calculate the force constant of the spring that will reduce the angular velocity of the rod to 1.50 rad/sec when it reaches the horizontal position. Assume the blocks A and B are weightless.

Edit question Calculate the radius of gyration for the system of two tubes and a seat that form a swing with respect to the axis A shown in the figure. The dimensions of this system are shown in the figure below.The tubes have a mass of 19 kg/m. This means that each meter of tube has a mass of 19. Tubes can be thought of as slender rods.The seat has a mass of 23 kg and can be considered as a thin plate. Note that several views of the swing are offered so that you can better understand which is the reference axis A and the necessary dimensions. As you solve the problem, take into account that you are going to fill a table with the following format. It must be filled with the corresponding units.

A shaft turning at a uniform speed carries two uniform discs A and B of masses 10kg and 8kg respectively. The centres of the mass of the discs are each 2.5mm from the axis of rotation. The radii to the centres of mass are at right angles. The shaft is carried in bearings C and D between A and B such that AC = 0.3m, AD = 0.9m and AB = 1.2m. It is required to make dynamic loading on the bearings equal and a minimum for any given shaft speed by adding a mass at a radius 25mm in a plane E. Determine: (a) The magnitude of the mass in plane E and its angular position relative to the mass in plane A (b) The distance of the plane E from plane A (c) The dynamic loading on each bearing when the mass in plane E has been attached and the shaft rotates at 200 rev/min. For the bearing loads in the opposite direction determine all the unknown values. For the bearing loads in the same direction, show the diagrams and equations only to use for a possible solution.
