2) Design a shaft connecting to gear (shaft 2). Provide complete calculations with shear force and bending diagram etc. Assume or select all stress concentration factors as recommended in text book, give reasons for such assumptions.
The design of the gear-and-shaft system shown requires that steel shafts of the same diameter be used for both AB and CD. It is further required that T max ≤60 MPa and that the angle ɸ D through which end D of shaft CD rotates not exceed 1.5°. Knowing that G = 77 GPa. determine the required diameter of the shafts.
