Question
PLEASE ANSWER NUMBER 3.12 MECH 222: PLEASE GIVE DETAILED SOLUTIONS AND CORRECT ANSWERS. I WILL REPORT TO BARTLEBY THOSE TUTORS WHO WILL GIVE INCORRECT ANSWERS.
Transcribed Image Text:3.11 The solid steel shaft carries the torques 7 = 750 N -m and T2 = 1200 N m.
Using L = L2 2.5 m and G = 83 GPa, determine the smallest allowable diameter
of the shaft if the shear stress is limited to 60 MPa and the angle of rotation of the
free end is not to exceed 4°.
