Power screw thread forms: friction and strength comparison Assess the statement: Square threads are not as strong as V-threads, but they offer less frictional resistance than Whitworth threads. Decide whether the statement is correct.

Difficulty: Easy

Correct Answer: True — the statement is correct

Explanation:

Concept
Square threads have zero flank angle → lowest friction among common forms, but less root strength compared to V/Whitworth because of a smaller shear area.
Whitworth (V) threads (55°) have higher friction due to the included angle and normal force components on the flanks.


Conclusion
The statement matches standard design comparisons.


Final Answer
True — the statement is correct
