In the ring-section torsion bar, the inner and outer radii are ri = 40 mm and ro = 80 mm, rod length is L = 1.6 m. The bar material is assumed to be ideal elastoplastic. The yield shear stress is ту = 120 MPa, the yield shear strain Yy = 0.006 rad, the radius of the elastic core is a = 60 mm. a) Sketch the distributions of shear stress t and shear strain y on the section. a) Determine the torsional moment that will affect the bar. (Nm) (Elastic-Plastic Torsional Moment) b) Calculate the total angle of twist that will occur in the bar. (rad) c) Find the minimum shear stress on the section. (MPa) M SOLUTION M O 2r. 0
