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 ____________
A. At the lower cross-section
B. At the built-in upper cross-section
C. At the central cross-section
D. At every point of the bar
Answer:B
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 ____________
A. At the lower cross-section B. At the built-in upper cross-section C. At the central cross-section D. At every point of the bar
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.
