List of top Physics Questions on Stress Strain Curve

The figure shows stress versus strain graphs of two materials A and B. If $Y_A$, $Y_B$ are the Young's moduli of materials respectively, then:

In the strain-stress curve for a material, if the ultimate strength and fracture points are close, then the material is

If the ultimate strength and fracture points are far apart in a stress - strain curve of a material, then the material is said to be

"Water is flowing through a horizontal pipe in stream line flow at the narrowest part of the pipe?"

Water is flowing through a horizontal pipe in streamline flow. At the narrowest part of the pipe:

A vessel completely filled with water has holes A and B at depths \( h \) and \( 3h \) from the top, respectively. Hole A is a square of side \( L \), and B is a circle of radius \( r \). The water flowing out per second from both the holes is the same. Then \( L \) is equal to:

Which of the following statements is correct?

The stress-strain graph of a material is shown in the figure. The region in which the material is elastic is

Strain vs stress curves for wires \(P, Q, R\). Which is correct?

The upper end of a wire of diameter $12\,mm$ and length $1\,m$ is clamped and its other end is twisted through an angle of $30^{\circ}$. The angle of shear is

The stress-strain graphs for two materials A and B are shown in figure. (Assume same scale)

The slope of the stress verses strain curve is :
