3 cards from this section. Quick, good the night before a test.
What is the formula for calculating the nominal strength of a bolt?
Remember what R, F_b, and A_n represent.
Define tensile strength in the context of bolts.
It's often reported in ksi.
What is the main formula for calculating nominal strength in bolts?
Look for the relationship between tensile strength and stress area.
The tensile stress area is typically larger than the gross area of a bolt. True or False?
Think about how threads affect the area.
Design a bolted connection requiring a nominal strength of at least 100 ksi. If using A490 bolts, what minimum tensile stress area must be achieved?
Rearrange the formula R = F_b A_n.
If A_g of a bolt is found to be 1 in², but due to threading, A_n is determined as 0.75 in²: What is the ratio of A_n to A_g, and discuss its implications.
Calculate and consider real-world application in design.
