(Solved): [AB bi-material] Inside the torsion bar AB in the figure two-material, diameter D, outer diameter 2 ...
[AB bi-material] Inside the torsion bar AB in the figure two-material, diameter D, outer diameter 2D, Since Mb=85kNm, find the torsional moment and shear stresses carried by each material. What is M1,M2, to 1, to 2 ? D=4cm,G1=800kN/cm2,R=D/2,G2=2?G1I0?=32?D4??max?=Io?Mb??R?=GI0?Mb?L?
• To solve this problem, use the torsion formula:
Where:
• ? is the shear stress
• M is the torsional moment
• r is the radius
• I is the polar moment of inertia
