The figure below shows, at left, a solid wheel of radius R = 0.600 m and mass 70.0 kg. Mounted directly to it and coaxial with it is a pulley with a much smaller mass and a radius of r = 0.230 m. The wheel and pulley assembly are on a frictionless axle. A belt is wrapped around the pulley and connected to an electric motor as shown on the right. The turning motor gives the wheel and pulley a clockwise angular acceleration of 1.67 rad/s?. The tension T., in the upper (taut) segment of the belt is 165 N. (a) What is the tension (in N) in the lower (slack) segment of the belt? N (b) What If? You replace the belt with a different one (one slightly longer and looser, but still tight enough that it does not sag). You again turn on the motor so that the wheel accelerates clockwise. The upper segment of the belt once again has a tension of 165 N, but now the tension in the lower belt is exactly zero. What is the magnitude of the angular acceleration (in rad/s2)? rad/s2
The figure shows a mass-pulley system. It consists of a pulley which is connected to the inertial frame through a frictionless revolute joint. The pulley has two sheaves, one with radius r=50 mm and the other with radius R=100mm. The sheaves are rigidly coupled together. The moment of inertia of the pulley is 1=0.03 kg m². A mass M-8 kg is suspended from the smaller sheave the pulley. A damper with damping coefficient C is connected between the mass and the inertial frame. A spring with stiffness k links the larger sheave to the inertial frame. The undamped natural frequency of the system is w₁ = 50 rad/s and the damping ratio is = 0.6. k www. 1.

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.

NAME Question 1 (6/20) ANSWER ON THE YELLOW PAGES The nose wheel of the landing gear of an aircraft is extended and retracted by applying a torque M to the rod BC by means of an shaft located at point B. The rod AO, on which the landing wheel is also located, has a combined mass of 100 kg which may be simplified to a point force at point G. The masses of the bars CD and BC may be neglected. If the point D is located underneath point B, the rod CD is at an angle of 30° to the vertical y-axis. At this position the landing gear should be kept stationary, dynamic effects may therefore be neglected. All components are made out of stainless steel with max=200 MPa and Imax = 75 MPa.
