Mathematics · Mechanical Properties of Materials
If two cap screws made of the same material have an equivalent stiffness of the threaded portion, and the first cap screw's threaded portion has a cross-sectional area twice that of the second cap screw's threaded portion, what is the relationship between their threaded portion lengths L1 and L2? (Stiffness k = AEL)
- 1L1 = L2
- 2L1 = 8L2
- 3L1 = 4L2
- 4L1 = 2L2✓
Correct answer
L1 = 2L2
