Q1: A composite torsion member consists of two solid shafts joined at flange B. Shafts (1) and (2) are attached to rigid supports at A and C, respectively. A concentrated torque T is applied to flange B in the direction shown. Determine the internal torques and shear stresses in each shafts. Also, determine the rotation angle of flange B. (1) 10 kN-m B 3400 mm (2) 4100 mm C For Q1:D1= 100 mm, D2=200mm G1-86 GPA and G2=38 GPA.
