Fatigue Strength is a variable that changes depending on load, shape and number of cycles
What is the general industry standard for the number of cycles when specifying Fatigue Strength ?
A few
1,000
1,000,000
10,000,000
Loads and Loads
How would you describe the difference between Yield and Ultimate Tensile Strength ?
(a) Modulus is the ratio of stress versus strain under a tensile load
Get out your calculator !! What is the stress placed on an object under a tensile load of 25kN, with a round cross section, of diameter 10 mm ?
I left my calculator at home !
2.5 MPa
32 MPa
0.032 MPa
What does Von Mises Stress measure ?
The average maximum or principle stress in three directions
The maximum shear stress in an element
The average stiffness in three directions
Not the foggiest
