Webb28 dec. 2024 · The modulus of elasticity equation is used only under conditions of elastic deformation from compression or tension. The modulus of elasticity is simply stress divided by strain: E=\frac {\sigma} {\epsilon} E = ϵσ. with units of pascals (Pa), newtons per square meter (N/m 2) or newtons per square millimeter (N/mm 2 ). WebbThe P/Q portion of our equation corresponds to the values at the point, which are $4.5 and 4. The ΔQ/ ΔP corresponds to the inverse slope of the curve. Recall slope is calculated as rise/run. In Figure 4.1, the slope is 3−4.5 6−4 3 − 4.5 6 − 4 = 0.75, which means the inverse is 1/0.75 = 1.33.
