The section of shaft shown in the figure is to be designed to approximate relative sizes of D=1.5d, and r=0.125d. The shaft is to be made of AISI 1035 CD steel and the groove is machined. The shaft is subjected to a completely reversed bending moment of 800 lbf.in, accompanied by a steady torque of 500 lbf.in. The shaft is to be used at 400°F and is expected to have a reliability of 0.99. Use a design factor of 2 and size the shaft for an infinite life using the Modified Goodman criterion. Determine the minimum diameter 'd'.

A gear drive consists of a 16-tooth 20° steel spur pinion and a 48-tooth cast-iron gear having a pitch of 12 teeth/in. For a power input of 1.35 hp at a pinion speed of 700 rev/min, select a face width based on an allowable contact stress of 100 kpsi. Refer to table number 14-8 for elastic coefficient. The face width based on an allowable contact stress of 100 kpsi is in.

A gear drive is required to transmit a maximum power of 22.5KW, the velocity ratio is 1:2 and the rpm of the pinion is 200 .the approximate center distance between the shaft may be taken as 600mm.the teeth has 20°stub involute profile.the static stress for the gear material ( which is cast iron ) may be taken as 60MPa and face width as 10 times the module.find the module, face width and number of teeth on each gear.Check the design for dynamic and wear loads. The deformation factor in the buckling equation may be taken as 80 and material combination factor for the wear as 1.4

Please help with the stress, mohir circle, etc. Thank you

Pls solve this, subject is machine design

Design a typical rigid flange coupling for connecting a motor and a centrifugal pump shafts. The coupling needs to transmit 15 KW at 1000 rpm. The allowable shear stresses of the shaft, key and bolt materials are 60 MPa, 50 MPa and 25 MPa respectively. The shear modulus of the shaft material may be taken as 84GPa. The angle of twist of the shaft should be limited to 1 degree in 20 times the shaft diameter. Note: show complete solution
