value .00 points 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 Tmax S 60 MPa and that the angle through which end D of shaft CD rotates not exceed 1.5°. Knowing that G 77.2 GPa, determine the required diameter of the shafts if T 1100 N m. (Round the final answer to one decimal place.) C 40m 00mm The required diameter...

Two shafts made of A992 steel, each with a diameter of 1.00 in, are supported by friction-less bearings at points A, B, and C; the support at point Dis fixed. Length L1 = 10 in. L2 = 29 in. L3 = 11 in, 14 = 11 in, and L5 = 12 in. Radius r1 = 6 in, and r2 = 4 in. Determine the angle through which end Brotates after the torques T1 = 80 lb-ft, and T2 = 40...
