Riveted joints: tearing efficiency and rivet pitch–diameter ratio If the tearing efficiency of a riveted joint is 50%, determine the ratio of the rivet hole diameter to the rivet pitch. Choose the correct value.

Q: Riveted joints: tearing efficiency and rivet pitch–diameter ratio If the tearing efficiency of a riveted joint is 50%, determine the ratio of the rivet hole diameter to the rivet pitch. Choose the correct value.

Given/Formula Tearing efficiency, ηt = (p − d)/p, where p = pitch, d = rivet hole diameter. Calculation ηt = 0.5 ⇒ (p − d)/p = 0.51 − (d/p) = 0.5d/p = 0.5 Final Answer 0.50

Correct Answer: 0.50

Explanation:

Given/Formula
Tearing efficiency, η_t = (p − d)/p, where p = pitch, d = rivet hole diameter.

Calculation
η_t = 0.5 ⇒ (p − d)/p = 0.51 − (d/p) = 0.5d/p = 0.5

Final Answer
0.50
