$\delta = \dfrac{PL}{AE} = \dfrac{\sigma L}{E}$ 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 ...

20 mar 2011 · This is calculated using the formula d = PL/AE, where d is the end deflection of the bar in meters, P is the applied load in Newtons, L is the length of the bar in meters, A is the cross sectional area of the bar in square meters, and E is the modulus of elasticity in N/m2.
It can be measured in terms of displacement, acceleration and velocity over time. These parameters are closely related to each other: if the measured parameter is acceleration, the other two can be found through a single and double integration.
Displacement diagrams are effectively plotting the displacement vectors of the joints as defined by the end of the bars. The displacement vector for the end of a bar is made up of two components: (1) an extension, of a magnitude defined by the bar force and the constitutive behavior of the bar which is parallel to the direction of the bar and (2) a

8 wrz 2022 · To find the elongation in this element, it has then used the PL AE P L A E formula, δ(ΔL) = Pydx AE δ ( Δ L) = P y d x A E. The link has then put the value of Py P y and integrated from 0 to L to get the total change in length.
