NEET Physics (general) MCQ Question
Which of the following statements about the mechanical properties of solids is correct?
The bulk modulus is defined as the ratio of hydraulic stress to hydraulic strain, and is always a positive value.
The elastic limit of a material refers to the maximum stress it can withstand without any deformation.
The design of pillars or columns does not significantly affect the load-bearing capacity of a building.
In a beam structure, reducing the weight of the beam does not influence its strength or cost.
Correct Answer
Detailed Explanation
The bulk modulus is defined as the ratio of hydraulic stress to the corresponding hydraulic strain, and its value is always positive as an increase in pressure leads to a decrease in volume. This aligns with the NCERT context discussing bulk modulus and its properties.
