Question

Stress-strain curve for mild steel showing stress $\sigma$ vs strain $\epsilon$ with points P, Q, R, S, T, and U marked.

Point on the graph	Description of the point
P	1. Upper Yield Point
Q	2. Ultimate Tensile Strength
R	3. Proportionality Limit
S	4. Elastic Limit
T	5. Lower Yield Point
U	6. Failure

Correct answer(C) P-3, Q-4, R-1, S-5, T-2, U-6SolutionBased on the standard stress-strain curve for mild steel:P is the Proportionality Limit (3), where stress is linear with strain.Q is the Elastic Limit (4), the maximum stress without permanent set.R is the Upper Yield Point (1), where yielding begins.S is the Lower Yield Point (5), where stress stabilizes during yielding.T is the Ultimate Tensile Strength (2), the maximum stress on the curve.U is the Failure (6) point where fracture occurs.Matching these gives: P-3, Q-4, R-1, S-5, T-2, U-6, which is option (C).Turn this into a strength.Explore AI-powered practice and doubt support with Success Tracker.
