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

Using the true stress \(\sigma_t = P/A\) rather than the engineering stress \(\sigma_e = P/A_0\) can give a more direct measure of the material’s response in the plastic flow range.
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
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.
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.
The benefits of using accelerometers to sense machine vibrations through casing measurements are well known and have been in general practice for generations of equipment. Typically, accelerometers internally generate an output voltage proportional to g’s, and 100mV/g is the common reference value.
