The expression for deformation and a given load \(\delta = PL/AE\) applies just as in tension, with negative values for \(\delta\) and \(P\) indicating compression.

$\delta = \dfrac{PL}{AE} = \dfrac{\sigma L}{E}$ To use this formula, the load must be axial, the bar must have a uniform cross-sectional area, and the stress must not exceed the proportional limit. If however, the cross-sectional area is not uniform, the axial deformation can be determined by considering a differential length and applying ...
The curve can be integrated to determine the overall GRMS value, as explain in Unit 7b. The same curve may also be integrated, through a separate method, to determine the velocity power spectral density and the displacement power spectral density. The purpose of this Unit is to describe this method.
\(\delta_P = \dfrac{PL^3}{48EI}\) where the length \(L\) and the moment of inertia \(I\) are geometrical parameters. If the ratio of \(\delta_P\) to \(P\) is measured experimentally, the modulus \(E\) can be determined. A stiffness measured this way is called the flexural modulus.

Displacement-time graphs show the displacement of an object from a fixed origin as it moves in a straight line. They show displacement (on the vertical axis) against time (on the horizontal axis) Displacement-time graphs can go below the horizontal axis whereas distance-time graphs can not.
Displacement-time graphs show the changing position of an object in motion. They also show whether an object is moving forwards (positive displacement) or backwards (negative displacement) Velocity = Gradient of a displacement-time graph. The greater the slope, the greater the velocity.
