Take G = 80 GPa. 2. A steel shaft consists of a hollow shaft 2m long, with an outside diameter of 100 mm and an inside diameter of 70 mm, rigidly attached to a solid shaft … A shaft must transmit 20 kW of power at 300 rev/min. The shear stress must not exceed 150 MPa. Calculate a suitable diameter. 3 A steel shaft 5 m long, having a diameter of 50 mm, is to transmit power at a rotational speed of 600 rev/min. If …

This report, entitled “Development of a Manufacturing Process for High-Power-Density Hollow Shafts”, presents a novel non-isothermal forming process for the hollow axle shaft, main shaft and pinion gear shaft. This process is evaluated in terms of formability, forming load and dimensional accuracy with FEM simulation. Design a hollow shaft required to transmit 11.2 MW at a speed of 300 r.p.m. The maximum shear stress allowed in the shaft is 80 MPa and the ratio of the inner diameter to outer diameter is 3/4. - …

Design a hollow shaft required to transmit 11.2 MW at a speed of 300 r.p.m. The maximum shear stress allowed in the shaft is 80 MPa and the ratio of the inner diameter to outer diameter is 3/4. - … Jun 07, 2018 · The natural frequency of hollow shaft is higher than the solid shaft with the same weight. The hollow shaft is costlier than a solid shaft. The diameter of the hollow shaft is more than the solid shaft and require more space. Hollow shafts are having a more polar moment of inertia, thus they can transmit more torque compared to solid shafts.

2. A hollow shaft is to transmit 200kW at 80 r.p.m. If the shear stress is not to exceed 60MPa and internal diameter is 0.6 of the external diameter, find the diameters of the shaft. . (Ans: 132mm, 79.2mm) 3. A solid steel shaft has to transmit 100kW at 160 r.p.m. Taking allowable shear stress as 70 MPa, find the suitable diameter of the shaft. Ans: d=50 mm 5. A solid circular shaft is subjected to a bending moment of 3000 N-m and a torque of 10 000 N-m. The shaft is made of 45 C 8 steel having ultimate tensile stress of 700 MPa and a ultimate shear stress of 500 MPa. Assuming a factor of safety as 6, determine the diameter of the shaft. Ans: d=90 mm 6. A line shaft rotating at 200 r.p.m. is to transmit 20 kW.

Shaft is a common machine element which is used to transmit rotary motion or torque. It generally has circular cross-section and can be solid or hollow. Shafts are supported on the bearings and transmit torque with the help of gears, belts and pulleys etc. Shafts are generally subjected to bending moment, torsion and axial force or a • Determine suitability of shaft design and/or necessary size of shafting. August 15, 2007 2 Introduction Shaft must have adequate torsional strength to transmit torque and not be over stressed.transmit torque and not be over stressed. Shafts are mounted in bearings and transmit power through devices such as gears, pulleys, cams and clutches.
