Q2 A steel shaft of different diameter carries a pulley and a motor as shown in Figure Q2.
The weights of the pulley and the motor are 4 kg and 40 kg, respectively with a similar
radius of gyration 0.5 m. If the shear modulus of shaft is given as G = 5 x 106 N/mm:
Torsional stiffness equation is k
(a) Identify the equivalent torsional stiffness of the steel shaft between the pulley and
the motor.
nd¹ G
321
Determine the responses of the pulley, 0₁ and the motor, 0₂ in terms of the unknown
amplitudes of A11 and A12, and phase angles of $1 and $2.
