An electric motor (with the following chacteristics: maxpower 35.00 kW, 850 max rpm)has its shaft designed as 600mmfrom center to center of the bearings.No design factor needs to be considered.The magnetic pull on the armature is 5.000 kNand concentrated midway between the bearings(acting as a point load). The shaft doesn't have keyways or shoulders. Consider reliability of 99%. Use SAE 1040 Steel hot rolled and machined. Report other assumptions made. Determine: a)Sketch a complete and correct Free Body Diagram. b) Calculate the maximum shear in the shaft. c)Calculate the maximum flexural moment inthe shaft. d)Determine the minimum diameter required for the shaft

Transcribed Image Text:An electric motor (with the following
chacteristics: maxpower 35.00 kW, 850 max
rpm)has its shaft designed as 600mmfrom center
to center of the bearings.No design factor needs
to be considered.The magnetic pull on the
armature is 5.000 kNand concentrated midway
between the bearings(acting as a point load).
The shaft doesn't have keyways or shoulders.
Consider reliability of 99%. Use SAE 1040 Steel
hot rolled and machined. Report other
assumptions made. Determine:
a)Sketch a complete and correct Free Body
Diagram.
b) Calculate the maximum shear in the shaft.
c)Calculate the maximum flexural moment inthe
shaft.
d)Determine the minimum diameter required for
the shaft
