Answer 2

Explanation:

The bending stress is zero at the neutral axis. When the load is acting downward, the bending stress is compressive above the neutral axis of section and tensile below it and these are denoted by σbc.cal and σbt.cal respectively. The bending stress is maximum at the extreme fibre
