6. A metallic rod of 500mm length and 50mm diameter, when subjected to a tensile force of 100kN at the ends, experiences an increase in its length by 0.5mm and a reduction in its diameter by 0.015mm. The Poisson's ratio of the rod material is а. 0.2 b. 0.3 С. 0.4 d. 0.5

The rectangular plate is subjected to force P that causes elongation in the horizontal direction and shrinking in the vertical direction as shown with the dashed line in the figure. Assume a = 550 mm, Δx = 2 mm, and Δy = 1.1 mm. Determine the shear strain γxy at point A?in micro rad Determine the shear strain γnt at point A?in micro rad What is the normal strain in the x-direction?micro£

If the block is subjected to the centrally applied force of 600kN, determine the average normal stress in the material. Show the stress acting on a differential volume element of the material

1.31 A steel rod, which is free to move, has a length of 200 mm and diameter of 20 mm at a temperature of 15°C. If the rod is heated uniformly to 115°C, determine the length and the diameter of this rod to the nearest micron at the new temperature if the linear coefficient of thermal expansion of steel is 12.5 x 10° m/m/°C. Is there a stress on the rod at 115°C?
