Assume the entire mass of a 10 kg wheel along its rim which is 50 cm from the axis of rotation (the wheel is considered a thin ring). The wheel is rotating at an angular speed of 20 rad/s. If the wheel is braked through the brake pads on the edge and stops 1 second later, the force exerted by the brake pads on the wheel is equal to

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.
