The value of \( \tan(90^\circ - \theta) \) in the graph gives
Show Hint
In a stress-strain graph, the slope in the elastic region corresponds to Young’s modulus.
Updated On: Jan 12, 2026
- Young's modulus of elasticity
- compressibility
- shear strain
- tensile strength
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understand the graph and the relationship.
The tangent of an angle in the stress-strain graph is related to the Young’s modulus of elasticity. Young's modulus is the ratio of stress to strain in the linear region of the graph.
Step 2: Conclusion.
Thus, \( \tan(90^\circ - \theta) \) represents the Young's modulus of elasticity in the graph.
Final Answer: \[ \boxed{\text{Young's modulus of elasticity}} \]

- The Hamiltonian for a one-dimensional system with mass \( m \), position \( q \), and momentum \( p \) is: \[ H(p, q) = \frac{p^2}{2m} + q^2 A(q) \] where \( A(q) \) is a real function of \( q \). If \[ m \frac{d^2 q}{dt^2} = -5q A(q), \] then \[ \frac{d A(q)}{d q} = n \frac{A(q)}{q}. \] The value of \( n \) (in integer) is:
