Question

Torsion bars are in parallel

• A. if same torque acts on each
• B. if they have equal angles of twist and applied torque apportioned between them
• C. if they have unequal angles of twist
• D. if their ends are connected together

Answer 1

Answer:

B. if they have equal angles of twist and applied torque apportioned between them

When two torsion bars are connected in parallel, they are surrounded by each other and have equal angles of twist. The torque acting on each bar is apportioned between them. The total torque applied on the composite shaft will be shared by both shafts. The angle of twist for both remains the same.
