A shaft is made up of components (1), (2) and (3). Component (1) is tubular with inner and outer diameters of d and 2d, respectively, whereas (2) and (3) have solid cross sections, each of diameter d. Components (1) and (2) are attached to a fixed wall at end B and to a rigid gear at C. Component (3) is attached to a rigid gear at H and to a fixed wall at K. Gears C and H. having diameters of 2D and D, respectively mesh without slipping. All shaft components have a shear modulus of G. Torques applied to the shaft system as shown a) Determine the torques carried by each element Express your answers in terms of T. b) What is the maximum shear stress in the shaft system? Express your answers in terms of T. D and d. At what point on the shaft does the maximum shear stress exist? Wwwwww 2D H (3) www/www
