4 cards from this section. Quick, good the night before a test.
What is the approximate Young’s Modulus for aluminum?
Compare it to steel's modulus, which is higher.
Define tensile strength in your own words.
Think about what happens to a rubber band when you stretch it too much.
What is the tensile strength of pure aluminum?
Refer back to our discussion on pure aluminum's properties.
Is aluminum’s Young’s Modulus greater than that of steel?
Think about how materials bend under the same load.
Given the tensile strengths of two aluminum alloys, A (200 MPa) and B (300 MPa), calculate the percentage increase in strength when moving from A to B. Discuss the implications for construction.
Use the percentage change formula.
An aluminum beam is subjected to cyclic loading that approaches its fatigue strength of 150 MPa. If the beam has a yield strength of 250 MPa, discuss the engineering considerations that must be taken into account to ensure safety.
Consider the difference between yield strength and fatigue strength when concerning structural durability.
