A tensile load of 190 kN is applied to a round metal bar with a diameter of 16 mm and a gage length of 50 mm. Under this load the bar elastically deforms so that the gage length increases to 50.1349 mm and the diameter decreases to 15.99 mm. Determine the modulus of elasticity and Poisson"s ratio for this metal.

An aluminium alloy rod of length 1.8m and rectangular cross-sectional of area 250mm^2 is subjected to a compressive load of 45kN. Young's modulus and Poisson's ratio for the material are: E = 71 GPa and v =0.33. Determine the decrease in length and increase in area of the bar.

The blue bar is made from steel with the following mechanical properties: Young's Modulus, E = 17x10° psi; Poisson's Ratio v = 0.31. The bar has a circular cross-section with diameter d= 0.50 in. being the length of each side. 557 lb 557 Ib 60 in. - Determine the following under the action of the axial load (assume elastic behavior): a. The bar's axial deformation, ô, in in.: b. The average axial or longitudinal strain, ELong: c. The change in the bar's diameter, in in.:

A steel rod with length equal to 12 ft, has a diameter of 0.8 inches in quarter of its length and a diameter of 0.4 inches the rest. If it is subjected to a tensile load of 6,500 lbs, what will be the total deformation of the bar if it has a modulus of elasticity E = 29.5 10^6 psi.
