A fixed 0.15 solid-disk pulley with a radius of 0.150 m is acted on by a net torque of 5.7 N. m. Calculate the angular acceleration of the pulley

What is relative velocity? in which condition is relative velocity known by adding the velocity of the first body and that of the second body

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.
