At a point in a strained material, if two mutually perpendicular tensile stresses of 2000 kg/cm2 and 1000 kg/cm2 are acting, then the intensity of tangential stress on a plane inclined at 15° to the axis of the minor stress will be :-A-125 kg/cm2B-250 kg/cm2C-500 kg/cm2D-1000 kg/cm2-B-250 kg/cm2

Question

At a point in a strained material, if two mutually perpendicular tensile stresses of 2000 kg/cm2 and 1000 kg/cm2 are acting, then the intensity of tangential stress on a plane inclined at 15&deg; to the axis of the minor stress will be :-A-125 kg/cm2B-250 kg/cm2C-500 kg/cm2D-1000 kg/cm2-B-250 kg/cm2

APTITUDE CRACK · Accepted Answer

The correct option is  B 250 kg/cm2 Shere stress = (sigma1 sigma2)/2*(sin2&theta;) = (2000 1000)/2*(sin2*15) = 250.
