Consider a shaft connected to motor at any location. Take its appropriate snaps. Assume that the shaft is failed and it has to be replaced. Measure all the required dimensions and variables required. Design and analyze a shaft considering

Static and Fatigue failure criteria, Factor of Safety, Manufacturing processes, Material properties

Solutions

Expert Solution

Static Failure Criteria

Fatigue Failure Criteria

Critical Speed

Factor of Safety

Factor of safety for shaft is simply given and calculated by, N = Yield Stress/Design Stress

Factor of safety must be considered before calculating Design stress. It depends upon

Working temperature
Surface properties
Operating Condition
Manufacturing Process

Manufacturing Process and Material Properties

Shafts usually undergo:

Bending stress
Torsional Stress
Fatigue Stress

Hence, material should be able to handle above stresses.

Most preferred material for shafts is steel and steel alloys.

Most preferred manufacturing process for shafts is forging, preferred cold forging.

An electric motor exerts a constant torque of τ=10N⋅m on a grindstone mounted on its shaft; the moment of inertia of the grindstone is I=2.0kg⋅m2. If the system starts from rest, find the work done by the motor in 8.0 s and the kinetic energy at the end of this time. What was the average power delivered by the motor? Part A:Suppose we now turn off the motor and apply a brake to bring the grindstone from its greatest angular...
