A rectangular block of material is subjected to a tensile stress of 110 N/mm2 on one plane and a tensile stress of 47N/mm2 on the plane at the right angles to the former. Each of the above

stresses is accompanied by a shear stress of 63 N/mm2 and that associated with the former

tensile stress tends to rotate the block anticlockwise. Find:

(i) The direction and magnitude of each of the principal stress and (5marks)

(ii) Magnitude of the greatest shear stress.

Asheet of steel 1.5 mm thick has nitrogen atmospheres on both sides at 1200oc and is permitted to achieve a steady-state diffusion condition. the diffusion coefficient for nitrogen in steel at this temperature is 6 x 10- 11 m2 /s, and the diffusion flux is found to be 1.2 x 10-7 kg/m2 -s. also, it is known that the concentration of nitrogen in the steel at the high-pressure surface is 4 kg/m3 . how far into the sheet from this high-pressure side will the concentration be 2.0 kg/m3 ? assume a linear concentration profile.
