Answer to Question #6618 in Mechanics | Relativity for pal

Question

a square prism of wood 50*50 mm in cross section and 300 mm long is subjected to a tensile stress of 4 t/cm2 along it's longitudinal axis and lateral compressive to a tensile stress of 2 t/cm2 along one pair of sides and a lateral tensile stress of 1-0 t/cm2 acting along the other pair of sides.If the value of E of the material is 1.5*10 to the power 5 kg/cm2,calculate it's changed dimensions.poisson's ratio for wood=.4
