What happens to a beam when it is subjected to bending?
Think about how a ruler bends when pressure is applied.
Define the neutral axis.
Consider where stress is at its least when the beam bends.
What does the term 'flexure' refer to?
Think about how beams change shape under load.
True or False: The neutral axis is the line of maximum stress.
Recall what happens to stress during the bending process.
A simply supported beam of length 6 m carries a point load of 10 kN at its center. Calculate the bending moment and shear force at the support.
Use the equilibrium principles for balance.
For a W-section beam, calculate the shear force at a section where the distance from the end is 2 m under a uniformly distributed load of 5 kN/m over 6 m.
Consider the area related to the distributed load.
