Physics · Mechanical Properties of Solids
What does the proportionality constant 'E' represent in the relation Stress = E × Strain?
- 1Modulus of Elasticity✓
- 2Young's Modulus only
- 3Modulus of Rigidity only
- 4Bulk Modulus only
Correct answer
Modulus of Elasticity
Explanation
सही उत्तर:
- (D) प्रत्यास्थता गुणांक
स्पष्टीकरण:
हुक के नियम से प्राप्त समीकरण
प्रतिबल
𝐸
विकृति
प्रतिबल=E×विकृति में 'E' एक आनुपातिकता नियतांक है।
इस नियतांक 'E' को प्रत्यास्थता गुणांक (Modulus of Elasticity) कहा जाता है।
यह अलग-अलग प्रकार के प्रतिबल और विकृति के अनुपात को दर्शाता है (जैसे यंग मापांक, आयतन प्रत्यास्थता गुणांक आदि)।
