The force vector of the quadriceps muscle group is oriented at 25 degrees to the mechanical axis of the tibia, and intersects the mechanical axis of the tibia 0.04 m from the center of the knee joint. draw an anatomically accurate, representative diagram of this situation.

On a average work day more than work place firs are reorted

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

Thermal stresses are developed in a metal when its a) initial temperature is changed b) final temperature is changed c) density is changed d) thermal deformation is prevented e) expansion is prevented f) contraction is prevented
