- An aluminum rod has a cross-sectional area of 0.19635 in2. An axial tensile load of 6000 lb. causes the rod to stretch along its length, and shrink across its diameter. What is the diameter before and after loading? answers in inches. complete solution with fbdThe structural efficiency in managing bending, shear and for steel vs concreteThe composite section shown in the figure is made up of C 15 x 40 and S 24 x 121. Determine the properties of composite section. a.Ix, Sx and rxb.Iy, Sy, and ry
- On construction site some of the columns and beams are made with steel. Compare among mild steel and high carbon steel.if the stress at failure and bending is 7200 PSI for small, perfect samples of a certain species of wood, what is the allowable bending stress for a piece of lumber with defects that are judged to reduce the strength by 40%?It is common to assume that reinforced concrete has a unit weight of 150 lb/ft3. If plain concrete has a unit weight of 145 lb/ft3, what percent of the volume of reinforced concrete is assumed to be reinforcing steel?
- 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.Show complete process. A tensile load of 150 kN is applied to a round metal bar with a diameter of 16 mm and a gage length of 80 mm. Under this load the bar elastically deforms so that the gage length increases to 80.1192 mm and the diameter decreases to 15.89 mm. Determine the modulus of elasticity (in MPa) and Poisson’s ratio for this metal.why are epoxy-coated bars sometimes used in the construction reinforced concrete?
