Transcribed Image Text:The segment AB of the steel torsion bar is a
cylindrical tube of constant 2-mm wall thickness.
Segment BC is a square tube with a constant wall
thickness of 3 mm. The outer dimensions of the cross
sections are shown in the figure. The tubes are
attached to a rigid bracket at B, which is loaded by a
couple formed by the forces P. Determine the largest
value of P if the shear stress in either tube is limited to
60 MPа.
