Q-5 A shaft carries four masses in parallel planes A, B, C and D in this order along its length. The masses at B and C are 18 kg and 12.5 kg respectively, and each has an eccentricity of 60 mm. The masses at A and D have an eccentricity of 80 mm. The angle between the masses at B and C is 100° and that between the masses at B and A is 190°, both being measured in the same direction. The axial distance between the planes A and B is 100 mm and that between B and C is 200 mm. If the shaft is in complete dynamic balance, determine: 1. The magnitude of the masses at A and D; 2. the distance between planes A and D; and 3. the angular position of the mass at D.

A hollow shaft of 1 m length is designed to transmit a power of 30 kW at 700 rpm. The maximum permissible angle of twist in the shaft is 1º. The inner diameter of the shaft is 0.7 times the outer diameter. The modulus of rigidity is 80 GPa. What is the outside diameter of the shaft?
Oh no! The bearing at the wall on the left has been damaged. It is now acting like another gear that can resist a moment(TW). You estimate the shaft has had torsional loading as follows: TA= 200 Nm TB= 530 Nm TC= 120 Nm TD= 150 Nm TW =? See the diagram for the direction of the torques on the shaft. The shaft diameter is 60 mm. The shaft looks ok but you are checking to see if it has exceeded the allowed shear stress for the shaft. Tw .600 mm 600 mm 600 mm A) Which segment has the maximum Torsion? B) What is the maximum shear stress due to torsion? C) Assume Tallow = 60 MPa did the shaft exceed the allowed shear?
1. A solid steel shaft ABCDE having diameter d = 40 mm turns with a constant angular velocity and freely in bearings at points A and E. The shaft is driven by a gear at C, which applies a torque T₂ = 625 N_m in the direction shown in the figure. Gears at B and D are driven by the shaft and have resisting torques T₁ and T3, acting in the opposite direction to the torque T2. We know T₁ = 400 N.m, but T3 is not explicitly given in the problem. Segments BC and CD have lengths LBC= 550 mm and LCD = 400 mm, respectively, and the shear modulus G = 80 GPa. Determine the maximum shear stress in each segment of the shaft and the angle of twist between gears B and D. pôrôć -LBC LCD T3 E
