Consider the rig set up in the figure above. This shows a force being applied to a hollow square section column at a distance from the Neutral Axis. This therefore produces both a direct stress and a bending stress. This question asks you to evaluate the stresses due to this combined loading. In this case the loading arm is 190 mm from the Neutral Axis of the square column to the point where the load is applied. The outside width of the column is 50.8 mm and the wall thickness is 1.5 mm. See the diagram below showing the cross-section through the column. If there is a load of 100 N calculate: • the second moment of Area I mm to two decimal places. • the bending moment M: Nm to two decimal places.

Consider the rig set up in the figure above. This shows a force being applied to a hollow square section column at a distance from the Neutral Axis. This therefore produces both a direct
stress and a bending stress. This question asks you to evaluate the stresses due to this combined loading.
In this case the loading arm is 190 mm from the Neutral Axis of the square column to the point where the load is applied. The outside width of the column is 50.8 mm and the wall
thickness is 1.5 mm. See the diagram below showing the cross-section through the column.
If there is a load of 100 N calculate:
• the second moment of Area I
mm4 to two decimal places.
• the bending moment M:
Nm to two decimal places.
