I need solutions for those problems CE 421 APPLIED SOLID MECHANICSHOMEWORK #11.A solid circular rod having diameter D=20 cm is to be replaced by a rectangular tubehaving cross-sectional dimensions D x 2D (which are measured to the wall centerlines ofthe cross-section). Determine the required minimum thickness tmin of the tube so that themaximum shear stress in the tube will not exceed the maximum shear stress in the solidbar2D2.
