In the linear portion of the stress-strain diagram, the tress is proportional to strain and is given by $\sigma = E \varepsilon$ since $\sigma = P / A$ and $\varepsilon = \delta / L$, then $\dfrac{P}{A} = E \dfrac{\delta}{L}$ $\delta = \dfrac{PL}{AE} = \dfrac{\sigma L}{E}$ To use this formula, the load must be axial, the bar must have a uniform ...

20 kwi 2015 · Vo needs to be calculated using the previous acceleration and the acceleration from two previous datasets ago or Ao-1 using the following kinematics equation: Vo = 1/2(Ao + Ao-1)*t + Vo-1
You're trying to find the displacement of the bar with the load distributed longitudinally at a point A. You use the formula displacement = PL/AE where P=load, L=length of member, A=cross-sectional area tangent to the load, and E=Young's modulus.
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.
Consider the beam of Fig. 1.14 axially loaded along the x axis in com-pression. If a small load or displacement is applied laterally at the location of the axial load, the beam bends slightly. If the lateral load is removed, the beam returns to its straight position.
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 rotation, which is undefined in magnitude, but is perpendicular to the direction of the bar (on the displacement ...
