During laboratory testing of an 6-inch aluminum-alloy rod with a cross sectional area of 0.32in², a tensile load of 50,000 lbs.is applied. Ifthe cross sectional area decreases to 0.3188in? and lengthens to 6.022 inches, what is the Modulus of Elasticity and Poisson's Ratio? E = 6/ɛ V = = -E(lateral)/ɛ(axial)

Using linear interpolation determine the DBTT of a given steel with the following Charpy tests results: 18 J at -18°C 28 J at -2°C 45 J at 5°C 60 J at 12°C -3.6°C -4.6°C -5.6°C -2.6°C

A No. 8 steel rebar is tested in tension. By monitoring the load reading of the testing machine, it was found that the specimen yielded at a load of 60,000 lbs and fractured at 75,000 lbs. Determine the following:   a. Tensile stresses at yield and at fracture. b. Estimate how much increase in length would occur at 75% of the yield stress in a 16-in. gauge length.

A wood beam reinforced by an aluminum channel section is shown in the figure. 150 mm 230 mm 38 mm 6.5 mm -163 mm- The beam has a cross section of dimensions 150 mm x 230 mm, and the channel has a uniform thickness of 6.5 mm. If the allowable stresses in the wood and aluminum are 8 MPa and 50 MPa, respectively, and if their moduli of elasticity are in the ratio 1 to 6, what is the maximum allowable bending moment for the beam? Enter the magnitude in kN · m. (Assume that the component parts of the beam are securely bonded by adhesives or connected by fasteners. Also, be sure to use the transformed-section method in the solution.) (No Response) 14.06 kN· m

An ASTM A615 grade 60 number 10 rebar with a gauge length of 8 in. was subjected to tension to fracture according to ASTM E-8 method. The load and deformation data were as shown in Table .Using a spreadsheet program, obtain the following:a. A plot of the stress–strain relationship. Label the axes and show units.b. A plot of the linear portion of the stress–strain relationship. Determine modulus of elasticity using the best-fit approach.c. Proportional limit.

Please provide all necessary information, explanation, and solutions. Thank you!

Which of the following options are correct for the section shown in figure? 40 mm 100 mm 100 mm Elastic section modulus Shape factor 40 mm 100 mm 100 mm

Please find the following? Use standard table units

please answer these two question 1.Explain the reason that flexural modulus of elasticity and compression test modulus of elasticity must be considered separately when both the flexural test and the parallel to grain compressive test caused normal stresses parallel to the grain of the wood. 2. Discuss the difference between isotropic and orthotropic materials for wood.
