The pressure drop needed to force water through a horizontal 1-in.-diameter pipe is 0.60 psi for every 12-ft length of pipe. determine the shear stress on the pipe wall. determine the shear stress at distances 0.3 and 0.5 in. away from the pipe wall. repeat the problem if the pipe is on a 20 degree hill. is the flow up or down the hill? explain.

If a simple machine reduces the strength of a force, what must be increased?

An ascending elevator, hanging from a cable, is coming to a stop. part a part complete identify all forces acting on the elevator from the list below. select all that apply. select all that apply. kinetic friction normal force tension weight static friction submitprevious answers correct part b draw a free-body diagram of the object. draw the vectors starting at the black dot. the location and orientation of the vectors will be graded. the exact length of your vectors will not be graded but the relative length of one to the other will be graded.
