Mechanical Properties of Solids MCQ questions with answers
The first 3 of 18 questions. Unlock the series for the rest, each with a solution.
Q1. The dimensional formula of Young's modulus is:
यंग प्रत्यास्थता गुणांक का विमीय सूत्र है:
- A. [M L⁻¹ T⁻²]
- B. [M L⁻² T⁻²]
- C. [M L T⁻²]
- D. [M L² T⁻²]
Solution
Young's modulus has the dimensions of stress (force/area) since strain is dimensionless, giving [M L⁻¹ T⁻²], the same as pressure.
चूँकि विकृति विमाहीन होती है, यंग गुणांक की विमाएँ प्रतिबल (बल/क्षेत्रफल) की विमाओं के समान होती हैं, जो [M L⁻¹ T⁻²] है, वही जो दाब की है।
Q2. Hooke's law was originally stated by Robert Hooke in the Latin form "Ut tensio, sic vis." The literal meaning of this phrase is:
हुक का नियम मूल रूप से रॉबर्ट हुक द्वारा लैटिन रूप "Ut tensio, sic vis" में व्यक्त किया गया था। इस वाक्यांश का शाब्दिक अर्थ है:
- A. As the stress, so the strain energy / जैसा प्रतिबल, वैसी विकृति ऊर्जा
- B. As the extension, so the force / जैसा विस्तार, वैसा बल
- C. As the force, so the time of recovery / जैसा बल, वैसा पुनर्प्राप्ति का समय
- D. As the pressure, so the volume / जैसा दाब, वैसा आयतन
Solution
"Ut tensio, sic vis" translates as "as the extension, so the force," i.e. the extension produced is directly proportional to the applied force within the elastic limit.
"Ut tensio, sic vis" का अनुवाद है "जैसा विस्तार, वैसा बल", अर्थात् प्रत्यास्थता सीमा के भीतर उत्पन्न विस्तार आरोपित बल के समानुपाती होता है।
Q3. Three of the following terms belong to the study of elasticity of solids, while one does not. Which one is the odd term out?
निम्नलिखित में से तीन पद ठोसों की प्रत्यास्थता के अध्ययन से संबंधित हैं, जबकि एक नहीं है। कौन-सा पद अलग (बेमेल) है?
- A. Capillarity / केशिकत्व (Capillarity)
- B. Elastic after-effect / प्रत्यास्थ पश्च-प्रभाव (Elastic after-effect)
- C. Elastic fatigue / प्रत्यास्थ थकान (Elastic fatigue)
- D. Elastic limit / प्रत्यास्थता सीमा (Elastic limit)
Solution
Elastic fatigue, elastic after-effect and elastic limit are all concepts in the elasticity of solids. Capillarity is a surface-tension phenomenon of liquids and is the odd one out.
प्रत्यास्थ थकान (elastic fatigue), प्रत्यास्थ पश्च-प्रभाव (elastic after-effect) और प्रत्यास्थता सीमा सभी ठोसों की प्रत्यास्थता की अवधारणाएँ हैं। केशिकत्व (capillarity) द्रवों का एक पृष्ठ-तनाव परिघटना है और यही बेमेल है।
