Free Sneak Peek

Here is a sneak peek of the questions included in this test set. Test your preparation by viewing the answer and detailed explanation before starting the timed exam.

Hooke's law states that within the elastic limit, stress is directly proportional to strain. The SI unit of the constant of proportionality (modulus of elasticity) is:

हुक का नियम बताता है कि प्रत्यास्थता सीमा के भीतर, प्रतिबल विकृति के अनुक्रमानुपाती होता है। समानुपाती स्थिरांक (प्रत्यास्थता गुणांक) का SI मात्रक क्या है?

$\text{N/m}^2$ or $\text{Pa}$$\text{N/m}^2$ अथवा $\text{Pa}$

$\text{N}\cdot\text{m}$

$\text{N/m}$

Dimensionless (no units)विमाहीन (कोई मात्रक नहीं)

Correct Answer: Option A

Explanation:

According to Hooke's law, $\text{Stress} = E \times \text{Strain}$. Strain is a dimensionless quantity (ratio of two lengths or volumes). Therefore, the modulus of elasticity $E$ has the same dimensions and unit as stress: $\text{Unit} = \frac{\text{Force}}{\text{Area}} = \text{N/m}^2 = \text{Pascal (Pa)}$. Thus, option A is correct.

हुक के नियम से, प्रतिबल = $E \times$ विकृति। विकृति एक विमाहीन राशि है। अतः प्रत्यास्थता गुणांक $E$ का मात्रक प्रतिबल के समान होता है: $\frac{\text{N}}{\text{m}^2} = \text{Pa}$। अतः विकल्प A सही है।

The typical stress-strain curve for a ductile metallic wire undergoing tensile loading is shown below.

Which point on this curve represents the limit up to which Hooke's law is strictly obeyed (stress is directly proportional to strain)?

तनन भार के अधीन एक तन्य धातु के तार के लिए विशिष्ट प्रतिबल-विकृति वक्र नीचे दर्शाया गया है।

इस वक्र पर कौन सा बिंदु उस सीमा को दर्शाता है जहाँ तक हुक के नियम का कड़ाई से पालन होता है (प्रतिबल, विकृति के सीधे समानुपाती होता है)?

Point E (Elastic Limit / Yield Point)बिंदु E (प्रत्यास्थता सीमा

Point P (Proportional Limit)बिंदु P (समानुपाती सीमा)

Point U (Ultimate Tensile Strength)बिंदु U (चरम तनन सामर्थ्य)

Point F (Fracture Point)बिंदु F (भंजन बिंदु)

Correct Answer: Option B

Explanation:

From origin O to point P (Proportional Limit), stress is strictly linear with strain, obeying Hooke's law. Between P and E (Elastic Limit), the material is still elastic and returns to its original dimension upon unloading, but stress is no longer strictly proportional to strain. Thus, Hooke's law is obeyed up to Point P. Option B is correct.

मूल बिंदु O से बिंदु P (समानुपाती सीमा) तक प्रतिबल और विकृति रैखिक रूप से संबंधित होते हैं तथा हुक के नियम का कड़ाई से पालन करते हैं। P से E तक पदार्थ प्रत्यास्थ तो रहता है किंतु प्रतिबल और विकृति समानुपाती नहीं रहते। अतः सही उत्तर बिंदु P है। विकल्प B सही है।

How Chapter-Wise Online CBT Tests Build Winning Habits for Future Competitive Exams

Focused chapter-wise CBT practice builds the speed, mental stamina, and analytical discipline required to ace CUET, JEE Main, NEET UG, NDA, CA Foundation, and College Entrance Exams.

Competitive Edge

Real-Time Clock Awareness & Pacing

समय प्रबंधन एवं गति नियंत्रण

In school examinations, students write answers without active pacing. In national entrance tests, students have barely 45-60 seconds per MCQ. Practicing with a 20-minute timer instills instinctive time-budgeting and prevents last-minute exam panic.

Mastery of the Elimination Technique

विकल्प निष्कासन विधि में दक्षता

Top rankers in competitive exams rarely compute every problem blindly. They spot subtle traps, evaluate extreme values, and eliminate 2 out of 4 distractors within seconds. Our 4-option sets teach critical distractor analysis.

CBT Screen Stamina & Digital Comfort

कंप्यूटर आधारित परीक्षा का सहज अभ्यास

Almost all major national exams (CUET, JEE, NEET, SSC, Banking) are 100% computer-based. Students who only study on paper experience eye strain and navigation mistakes on exam day. Early CBT practice creates effortless digital fluency.

Immunity to Negative Marking

सटीकता और नकारात्मक अंकन से सुरक्षा

Careless errors—such as misreading "NOT" or "EXCEPT"—ruin thousands of competitive aspirations each year. Regular objective testing builds the habit of double-checking question keywords before locking answers.

Instant Diagnostic Feedback Loop

तत्काल त्रुटि निवारण एवं आत्म-मूल्यांकन

Traditional paper tests take weeks to grade, by which time the student has forgotten their thought process. TargetExams provides instant scorecards and step-by-step solutions while the conceptual puzzle is still fresh.
