A motor with an output torque of Tm-1200N.m is used to drive the shaft against a resistance load F=6.8 KN at pulley A. The clutch shown is used to connect the shaft with the motor. An axial force Fa=1.5 KN is required for the clutch engagement; assume that all axial force is taken by bearing B. The shaft is made of CI with Sut-400 Mpa and Suc- 800 Mpa E=14 Gpa. 1- Find the factor of safety guarding against shaft failure, using all possible theories. 2- Two identical columns are used to support the shaft at bearing A and B. The end supports of the column is fixed-round ends with C=1.0 for buckling in plane of the and C-0.25 for out-of-plane buckling. Find the factor of safety guarding against column buckling if the column length L=3.0 m. The columns are made of steel with Sy- 450 Mpa, Sut-880 Mpa, E=205 Gpa. 3- Find the angular deflection of shaft end in A. PH d-45 B F2-6.8 KN L F2=6.8 KN, D=70 Bearing support b=25 1 h=55 с A motor with an output torque of Tm-1200N.m is used to drive the shaft against a resistance load F=6.8 KN at pulley A.
