MCQ - 115-10582

Question:

An iron bar of length L m and cross section A m2 is pulled by a force of F Newton from both ends so as to produce and elongation in meters. Which of the following statement statements is correct?

Elongation is inversely proportional to length L
Elongation is directly proportional to cross section A
Elongation is inversely proportional to A
Elongation is directly proportional to cross section A

Correct Answer: C

Explanation:

The elongation of the bar is directly proportional to the tensile force and the length of the bar and inversely proportional to the cross-sectional area and the modulus of elasticity. Hooke's experimental law may be given by Equation

This simple linear relationship between the force (stress) and the elongation (strain) was formulated using the following notation.
