1. A bend test is used for a certain hard material. If the transverse rupture strength of the material is known to be 1000 MPa, what is the anticipated load at which the specimen is likely to fail, given that its width = 15 mm, thickness = 10 mm, and length = 60 mm? 2. A torsion test specimen has a radius = 25 mm, wall thickness = 3 mm, and gage length = 50 mm. In testing, a torque of 900 N-m results in an angular deflection = 0.3°. Determine (a) the shear stress, (b) shear strain, and (c) shear modulus, assuming the specimen had not yet yielded. (d) If failure of the specimen occurs at a torque = 1200 N-m and a corresponding angular deflection = 10°, what is the shear strength of the metal?

Step 1
To determine the anticipated load at which the specimen is likely to fail in a bend test, we need to use the formula: Load = (3 x transverse rupture strength x width x thickness^2) / (2 x length) Plugging in the given values, we get: Load = (3 x 1000 x 15 x Show more…

A three-point bending test is performed on a spinel (MgAl_O_) specimen having a rectangular cross section of height $d 3.8 \mathrm{mm}$ $(0.15 \text { in. })$ and width $b 9 \mathrm{mm}(0.35 \text { in. }) ;$ the distance between support points is $25 \mathrm{mm}$ $(1.0 \text { in. })$ (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 $310 \mathrm{N}\left(70 \mathrm{lb}_{f}\right)$
To determine the nominal or engineering stress and strain experienced by a specimen of a material while it is subjected to a tension test, and to be able to read important values from a conventional stress-strain diagram obtained from the test. A tension test is being conducted on a steel-rod specimen with a gauge length of L0=50 mm and initial diameter of d0=13 mm. Data were collected to form the conventional stress-strain diagram as shown. From the diagram, f = 510 MPa , e = 701 MPa , g = 585 MPa , and h = 0.154 mm/mm . Part B - Nominal or engineering stress in the specimen Assuming that the stress is constant over the cross-sectional area and if the tension force used is P = 14.0 kN , find the nominal stress experienced by the rod. Part C - Force needed to reach the ultimate stress Determine the force P needed to reach the ultimate stress in the steel-rod specimen.
