# 1)If a circular bar in pure tension has a radius of 0.1 m

### Customer Question

1)If a circular bar in pure tension has a radius of 0.1 m and a total lenght of 10m experiences a total angle of twist of 0.1 degrees at the right end. What is the maximum shear strain 2m from the left end?
2)A hollow and a solid circular shaft are constructed of the same material, have the same length and the same radius r. The inner radius of the hollow shaft is 0.6r. Assuming the same torque is applied to both shafts, determine the ratio t(hollow max)/t(solid max)

what are the answes for both questions?
Expert:  StructuralEng replied 10 months ago.

Question 1 doesn't make sense. If it's in pure tension there would be no angle of twist

The second question doesn't make sense either. You're stating they both have the same r, so is t (solid) equal to r (solid)?

Also, you need to make an assumption about the angle of twist or shear stress or something that links the two together.
