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.
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 ...

12 wrz 2022 · By taking the derivative of the position function we found the velocity function, and likewise by taking the derivative of the velocity function we found the acceleration function. Using integral calculus, we can work backward and calculate the velocity function from the acceleration function, and the position function from the velocity function.
Displacement diagram (to Scale) Horizontal Displacement = PL AE to the left vertical displacement = 12.9 PL AE
27 cze 2024 · The basic formula to calculate displacement is a reworking of the velocity formula: d = vt. Where d is displacement, v is average velocity, and t is the time period, or the time it took to get from point A to B. If the object has constant velocity, solving for displacement is straightforward.
• Determine the relative displacement of the free end at A with respect to the fixed end at D. The modulus of elasticity for aluminum is 10 x 10 6 psi • Solve the problem using the ( a)discrete element method, and (b) the superposition method.
