3 cards from this section. Quick, good the night before a test.
What is the plastic moment strength (M_p) if Z = 20 in^3 and F_y = 30 ksi?
Use the formula M_p = Z * F_y.
Define nominal strength in one sentence.
Think about the definition and the implications of strength.
What is the formula for calculating nominal strength for stable compact sections?
Think about how both Z and F_y contribute to bending strength.
True or False: A higher plastic section modulus increases the nominal strength of a beam.
Recall how Z relates to bending capacity.
A steel beam has a plastic section modulus of 25 in^3 and is made from steel with a yield strength of 40 ksi. Calculate the nominal strength and discuss its application in a real-world situation.
Remember to multiply the plastic section modulus by the yield strength.
Assuming a steel beam has a nominal strength of 1200 kip-in and a section modulus of 30 in^3. What is the yield strength? Provide reasoning.
Rearranging the nominal strength formula will help you find the yield strength.
