Question
A hollow circular nylon pipe (see Fig 1-23) supports a load P = 7800 N, which is uniformly di stributed around a cap plate at the top of the lower pipe. A second load Pg is applied at the bottom. The inner and outer diameters of the upper and lower parts of the pipe are d, = 51 mm, d, = 60 mm, d, = 57 mm, and d 63 mm, respertively. The upper pipe has a length L, = 350 mm; the lower pipe length is L, = 400 mm. Neglect the self-weight of the pipes. (a) Find P so that the tensile stress in upper part is 14.5 MPa. What is the resulting stress in the lower part? (b) If P, remains unchanged, find the new value of P, so that upper and lower parts have same tensile stress. (c) Find the tensile loads in part (b) pipe stress analysis be 3.56 mm and is 7.63 mm. Two-tier hanging e segments for the egment is known to bottom of the pipe L., = 350 mm PA 12 = 4X) mm Po
