I made a custom made shaft using solidworks. and it's designed with a custom made steam turbine wheel. My question is how do I know what fillet and chamfer to use for the turbine wheel and shaft shoulder. The computed force on the shaft is really low. I just want to know if 0.5 mm radius on the shoulder and 0.50 mm chamfer for the turbine wheel will do. (All units in millimeters)
Determine the diameter, in inches, of a circular steel rod that could withstand a tensile force of 95,000 pounds? If the steel rod was 3 feet long, how much would it elongate in inches?
