The mover pushes a dresser on an inclined plane 5 meters long and 3 meters high. If the dresser is 961 newtons and the mover exerts a
force of 600 newtons, then what is the mechanical efficiency of the
incline plane? What is the actual mechanical advantage?

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.
