Find the diameter of a shaft to transmit twisting moments varying from 800 N-m to 1600 N-m. The ultimate tensile strength for the material is 600 MPa and yield stress is 450 MPa. Assume the stress concentration factor = 1.2, surface finish factor = 0.8 and size factor = 0.85.

A shaft/hub connection transmits a torque C =60N.m. We use a rectangular key (W=14mm x H=9mm) with a length of 30mm for a 45mm diameter shaft. Calculate the force exerted on the key.Calculate the compressive and shear stress.

Find the diameter of a shaft made of (37 Mn 2 steel) having the ultimate tensile strength as (600 MPa) and yield stress as (440 MPa). The shaft is subjected to completely reversed axial load of (200 kN). Neglect stress concentration factor and assume surface finish factor as (0.8). The factor of safety may be taken as (1.5). (After the diameter was found, correct it for the actual size factor). mechanical design pls solve fast

Pls solve this, subject is machine design

A cylindrical steel shaft is required to transmit a bending moment of 1000 Nm and a torque of 2200 Nm with a safety factor against yielding of 3. If the steel has a yield stress of 250 MPa, find the minimum permissible diameter for the shaft. Use von Mises’ theory of yielding.

A section of a rotating shaft is under an alternating bending moment of 70Nm and a torque of 35Nm. The yield strength of the material is 560 MPa and the ultimate tensile strength of the material is 700 MPa. The estimated actual endurance strength is assumed to be 210 MPa and the stress concentration factor is 1.5 for well rounded fillet. (Design Factor = 2) Determine the minimum diameter of the section of the shaft: D =  mm

As part of an innovation policy introduced within the company to research into newer design of swings, the R and D department is proposing that work should be carried out on motorized swings. The initial consideration is to use an electric motor to spin the central shaft. For this purpose a hollow shaft of diameter ratio 3:5 is required to transmit 600 kW at 110 rpm, the maximum torque being 12% greater than the mean. The shear stress is not to exceed 60MPa and the twist in a length of 3m is not to exceed 1 Degree (1º). Calculate the minimum outer diameter (D) to satisfy both these conditions. Take G = 80GN/m2

1) A stepped steel shaft, shown below, is used in a spur gear reducer. The shaft is subjected to a constant axial stress (A=40 MPa), a constant bending moment that results in a variable stress (M=60 MPa) due to loads by bearings and gears, and a steady torque (T-80 MPa). However, these stress values do not take into account stress concentration factors. The shaft has a D=45 mm, d=30 mm, and r=6 mm, resulting in kr,bend=1.34, Kr,axial=1.48, and kf,tor 1.2. The shaft is made of steel with S₁=1006 MPa, S,=648 MPa, and H₂=229. The size of the shaft results in a gradient factor of CG=0.9. The shaft has a fine-ground finish. A 90% reliability is required. Verify the stress concentration factors are correct for this shaft geometry. Calculate the safety factor relative to infinite life (105 cycles). If the safety factor is less than one (i.e., shaft fails), find the number of cycles to failure. (60) M
