If a bar of large length when held vertically and subjected to a load at its lower end, its won-weight produces additional stress. The maximum stress will be ________

Civil Engineering : Strength of Materials - Quiz(MCQ)

At every point of the bar

At the lower cross-section

At the central cross-section

At the built-in upper cross-section

Correct Answer : At the built-in upper cross-section

Explanation : The stress is the load per unit area. After the addition of weight in the bar due to its loading on the lower end the force will increase in the upper cross-section resulting in the maximum stress at the built-in upper cross-section.
