- The A-36 solid steel shaft is 2 m long and has a diameter of 60 mm. It is required to transmit 60 kW of power from the motor M to the pump P. Determine the smallest angular velocity the shaft if the allowable shearstress is tallow = 80 MPa.The shaft consists of a solid segment AB and a hollow segment BC, which are rigidly joined by the coupling at B. If the shaft is made from A-36 steel, determine the maximum torque T that can be applied according to the maximum shear stress theory. Use a factor of safety of 1.5 against yielding.The composite shaft consists of a mid-section that includes the 1-in.-diameter solid shaft and a tube that is welded to the rigid flanges at A and B. Neglect the thickness of the flanges and determine the angle of twist of end C of the shaft relative to end D.The shaft is subjected to a torque of 800 lb.ft.The material is A-36 steel.
- The turbine develops 300 kW of power, which is transmitted to the gears such that both B and C receive an equal amount. If the rotation of the 100-mm-diameter A992 steel shaft is v = 600 rev>min., determine the absolute maximum shear stress in the shaft and the rotation of end D of the shaft relative to A. The journal bearing at D allows the shaft to turn freely about its axis.The shaft has a radius c and is subjected to a torque per unit length of t0, which is distributed uniformly over the shaft’s entire length L. If it is fixed at its far end A, determine the angle of twist f of end B. The shear modulus is G.Solve Prob. 7.29 if =0.
- The 6061-T6 aluminum alloy solid shaft is ixed at one end but free at the other end. If the shaft has a diameter of 100 mm, determine its maximum allowable length L if it is subjected to the eccentric force P = 80 kN.2. The block has a mass of 5.8 kg and rests on the smooth plane. Determine the unstretched length of the spring. Round to three significant figures.The hollow 6061-T6 aluminum shaft has an outer and inner radius of co= 40 mm and ci = 30 mm, respectively. Determine the angle of twist of end A. The support at B is flexible like a torsional spring, so that TB = kB fB, where the torsional stiffness is kB = 90 kN # m>rad.
- If the 20-mm-diameter rod is made of A-36 steel and the stiffness of the spring is k = 50 MN>m, determine the displacement of end A when the 60-kN force is applied.The two shafts are made of A-36 steel. Each has a diameter of 25 mm and they are connected using the gears fixed to their ends. Their other ends are attached to fixed supports at A and B. They are also supported by journalbearings at C and D, which allow free rotation of the shafts along their axes. If a torque of 500 N # m is applied to the gear at E, determine the rotation of this gear.The shaft has an outer diameter of 100 mm and an inner diameter of 80 mm. If it is subjected to the three torques, determine the absolute maximum shear stress in the shaft. The smooth bearings A and B do not resist torque.
