Question
The specimen shown has been cut from a 5 -mm-thick sheet of vinyl $(E=3.10 \mathrm{GPa})$ and is subjected to a 1.5 -kN tensile load. Determine$(a)$ the total deformation of the specimen, $(b)$ the deformation of its central portion $B C$.
Step 1
We consider the forces acting away from the section as positive (tensile in nature) and the forces acting towards the section as negative (compressive in nature). We resolve the forces at the fixed support and then resolve them in each section. Show more…

A three-point bending test is performed on a spinel $\left(\mathrm{MgAl}_{2} \mathrm{O}_{4}\right)$ specimen having a rectangular cross section of height $d=3.8 \mathrm{~mm}(0.15 \mathrm{in}$.) and width $b=9 \mathrm{~mm}(0.35 \mathrm{in}$.); the distance between support points is $25 \mathrm{~mm}(1.0 \mathrm{in}$.). (a) Compute the flexural strength if the load at fracture is $350 \mathrm{~N}\left(80 \mathrm{lb}_{\mathrm{f}}\right)$. (b) The point of maximum deflection $\Delta y$ occurs at the center of the specimen and is described by $$ \Delta y=\frac{F L^{3}}{48 E I} $$ where $E$ is the modulus of elasticity and $I$ is the cross-sectional moment of inertia. Compute $\Delta y$ at a load of $310 \mathrm{~N}\left(70 \mathrm{lb}_{\mathrm{}}\right)$.

A bar of a steel alloy that exhibits the stressstrain behavior shown in Figure $6.22$ is subjected to a tensile load; the specimen is $375 \mathrm{~mm}(14.8 \mathrm{in}$.) long and has a square cross section $5.5 \mathrm{~mm}(0.22 \mathrm{in}$.) on a side.(a) Compute the magnitude of the load necessary to produce an elongation of $2.25 \mathrm{~mm}(0.088$ in.). (b) What will be the deformation after the load has been released?
