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.

A12 mm diameter shaft runs in a plain cylindrical bush 30 mm long that is located in an 18 mm diameter hole in a housing. the shaft-inner bush fit is h8 f and the outer bush-housing fit is h7-p6. make a fully cimensioned sketch of the bush with tolerances. find the maximum and minimum clearance or interference for both fits on the inner and outer diameters of the bush
