Your company is designing a part that will see a cyclically applied load, before calculating the number of cycles till failure you need to determine the endurance limit. Determine the endurance limit on the given loading, geometry, and material.

Given Data:

Sut = 800 MPa

Sy = 310 MPa

Operating temperature = 120 degrees C

Surface Finish: Hot-Rolled

Specimen Rotating? Yes

Cross-section: Solid Circle

d = 20 mm

Reliability = 75%

Stresses Min(MPa) Max(MPa) Mean(MPa) Amp(MPa)

Scenario Suppose you are designing a piece of software for a packaging company. A part of the software involves an items capacity limit mechanism to prevent a package from being shipped when it's filled past its capacity. Aim Define a class called Package, which will have a maximum item capacity of 6. The package should be initialized with the number of items. If the number of items exceeds the capacity limit during initialization, it should print out a message indicating...
