3. A flat annular steel flywheel of outer radius 0.5 m and inner radius 0.125 m with p = 7800 kN*s?/m* and v = 0.3 is to be shrunk fit around a solid steel shaft. The shrinking allowance is 0.1 mm. Both materials are the same type of steel with E = 210 GPa. Determine the RPM when the shrink fit loosens as a result of rotation.

Assume that the gear keyed to the shaft shown in the figure below is a Class 50, cast iron flywheel of 15-inin outside diameter and 1-in thickness. The hub is 4-in dia and 3-in thick. The shaft is steel. Determine the critical frequency of shaft whirl for the assembly shown using the following dimensions: a = 4 in , b = 12 in , l = 14 in , the shaft diameter is 2 in. Assume the following: The applied transverse force PP and the Torque TT to be zero. The mass of the steel shaft can be ignored.
can you please find an solution for this?
Please I want answer of that question from these choices
Please draw the figure. Thank you so much.An engine flywheel and a clutch plate are both connected to a transmission shaft. Let the moment of inertia of the flywheel be I1 and its angular velocity ω1, and let the moment of inertia of the clutch plate be I2 and its angular velocity is ω2. The two discs have then been combined by forces which are applied at their axes of rotation so as not to cause any torque. The discs then reached a common final angular velocity after rotational collision. Find the expression for the final angular velocity.

The picture shows the rear swivel axle bearing design of a 4-wheel wagon. It is known that the speed of the wagon wheels is n = 37 rpm. The total radial load carried by the wagon is given as Fr= 16060 Newtons. In addition, due to road conditions, Fa axial load is applied to the wagon. If the axial load on the A bearing is 10% of the radial (vertical) load on this bearing, calculate the dynamic load number (C) of the bearing in the A bearing in Newtons for 18616 hours of life. fo*Fa/Co = 0.345 Pi=3.14
