$\delta = \dfrac{PL}{AE} = \dfrac{\sigma L}{E}$ 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.
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
12 wrz 2022 · Calculate position vectors in a multidimensional displacement problem. Solve for the displacement in two or three dimensions. Calculate the velocity vector given the position vector as a function of time.
8 wrz 2022 · $$\delta (\Delta L)= \frac{P_y dx}{AE}$$ The link has then put the value of $P_y$ and integrated from 0 to L to get the total change in length. The formula $\frac{PL}{AE}$ is valid only when the load P applied is gradual (that is it is a gradually applied load that increases from 0 to P).
(a) Determine the deflection of a coil spring under the influence of an axial force \(F\), including the contribution of bending, direct shear, and torsional shear effects. Using \(r = 1\ mm\) and \(R = 10\ mm\), compute the relative magnitudes of the three contributions.
