MECHANICS OF MATERIALS. BE VERY URGENT PLSSSS!!!!!!!!!!!
The preliminary design of a large hollow shaft connecting the generator in an engine has shown that the inner and outer diameter should be 200 mm and 300 mm respectively. If the permitted shear stress is 120 MPa; a.) Find the largest torque and rotation angle that the shaft can transmit b.) In case of solid shaft with the same weight and length, find the greatest torque and angle of rotation that it...

Wind energy is gaining increased attention, so there is in turn an increased interest in windmill technology. Because the windmill blades (vanes) rotate about a central axis, one of the most important physical properties of a windmill is its moment of inertia. Given is a picture of a typical windmill, where the geometry and center of mass of one of the vanes is illustrated. If the moment of inertia about axis A is 445 kg·m2 and about axis B is...

A ball of mass 5.0 kg is suspended by two wires from a
horizontal arm that is attached to a vertical shaft, as shown in
the figure. The shaft is in uniform rotation about its axis. The
rate of rotation is adjusted until the tensions in the two wires
are EQUAL. At that speed, what is the radial acceleration of the
ball?
