rod diameterthat can be used.Answer:=__________mm

The figure shows a cutaway view of an assembly in which a solid steel [= 80 GPa] rod (1) is fitted inside of a brass [= 46 GPa] tube (2). The tube is attached to a fixed plate at, and both the rod and the tube are welded to a rigid end plate at. The outside diameter of the tube is= 55 mm, and its wall thickness is= 3 mm. Assume= 620 mm,= 380 mm, and= 660 N-m. If the allowable rotation angle of endis 5, determine the minimum rod diameterthat can be used.Answer:=__________mm
