5. The equilateral triangular tórsión member has sides equai lU D thickness t (Figure a). Figure b shows the same cross-section, but with a cut at half-length of the right-side (open cross-section). If the maximum allowable shear stress were to be Tmax: max Ja (a) Determine the ratio of the torsional constants, Jb 프 for both Tb (b) Determine the ratio of the maximum allowable twist moment, sections. ea (c) Determine the ratio of the maximum allowable angle of twist per unit length, Ob for both sections. For both sections assume Tmay = 100 MPa, G =70 GPa, d316 cm, t=1 cm. (a) (b)
