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 ...

Displacement-time graphs show the displacement of an object from a fixed origin as it moves in a straight line. They show displacement (on the vertical axis) against time (on the horizontal axis) Displacement-time graphs can go below the horizontal axis whereas distance-time graphs can not.
12 wrz 2022 · Find the functional form of velocity versus time given the acceleration function. Find the functional form of position versus time given the velocity function. This section assumes you have enough background in calculus to be familiar with integration.
Worked Example 1. Figure 1 shows the displacement-time graph for a tennis ball which is thrown vertically up in the air from a player’s hand and then falls to the ground. The graph illustrates the motion of the ball.
