Here we show a cylindrical shaft (d = 0.02 m). The shaft is pre-loaded in tension between the two bearings. A helical gear is located between the two bearings and exerts both a torque and vertical and horizonal loads. On the cantilevered tip there is a vertical load and a torque. Analyze the system and identify the stress and worst-case scenario. a) List the types of stresses in the shaft. b) Calculate the shaft FBD, shears, and moments. c) Calculate the stress for each of the types identified. d) Where is the highest stress point located along the length of the shaft? e) At the highest stress location along the shaft, what are all the stresses for A, B, C and D on the cylindrical cross section? f) Where on the cylindrical cross section is the highest stress located (A, B, C, or D)? 3 N 10 N-m 0.1 m 30 kg 6 N 0.1 m 9N 0.2 m DO 10 N-m B 20 kg Here we show a cylindrical shaft (d = 0.02 m).
