A horizontal bar is attached to a wall. When a force of 1 kN is applied at point A, the deflection at point A is $\delta_{AA} = 0.5$ mm. When a 1 kN force is applied at point B, the deflection at point A is $\delta_{AB} = 0.2$ mm. (A given deformation due to a unit load is known as a flexibility factor.) 1 kN B A 1 kN B A Part A - Larger load What is the change in the length of the bar if there is a single load of 6.6 kN applied to the right at point A?
