Question
For problem 3.68, I know how to do parts (a-e), my question is how to get the maximum slope at the supports if the material was carbon steel with E=30e6 psi. Should I do the calculations all over again for carbon steel? 3-68' to A countershaft carrying two v belt pulleys is shown in the figure. Pulley A receives power from 3-71 a motor through a belt with the belt tensions shown. The power is transmitted through the shaft and delivered to the belt on pulley B. Assume the belt tension on the loose side at B is 15 per- cent of the tension on the tight side. (a) Determine the tensions in the belt on pulley B, assuming the shaft is running at a constant speed. (b) Find the magnitudes of the bearing reaction forces, assuming the bearings act as simple (c) supports one set for Draw e and bending moment diagrams for the shaft. If needed, make the horizontal plane and another set for the vertical plane. (d) At the point of maximum bending moment, determine the bending stress and the torsional shear stress. (e) At the point of maximum bending moment, determine the principal stresses and the max imum shear stress. 230 mm 280 mm 30-mm dia. 300 mm 12 in 250-mm dia. 500 lbf 75 lbf 8-in dia. 270 N 400-mm dia. n dia. 1800 N 10-in dia Problem 3-69* Problem 3-68.Explanation / Answer
Till Bending moment calculation (Bending moment diagram), the calculation should be same irrespective of the material. Material properties are introduced only during the deflection and slope calculation.
You can calculate Deflection/slope using moment-curvature relationship or using moment area method.
