In above figure, the compound solid aluminum rod is subjected to a tensile force P. Make the assumption that E = 69 GPa, d1 = 16 mm, L1 = 600 mm, d2 = 25 mm, L2 = 900 mm, and σy = 276 MPa. Calculate the largest amount of strain energy that can be stored in the rod without causing any yielding.
In above figure, the compound solid aluminum rod is subjected to a tensile force P.
A solid aluminum [E = 76 GPa] rod (1) is connected to a solid bronze [E = 93 GPa] rod (2) at flange B, as shown. Aluminum rod (1) has an outside diameter of 31 mm and bronze rod (2) has an outside diameter of 15 mm. The norma stress in the aluminum rod must be limited to 128 MPa, and the normal stress in the bronze rod must be limited to 97 MPa. Assume L1 = 180 mm and...
A solid aluminum post is subjected to a vertical force of P = 70 kN and a concentrated torque of T = 3.25 kN-m, acting in the directions shown. The length of the pole is L = 90 mm and the diameter is 60 mm. a) Calculate the normal and shear stresses at point H (in MPa) [Ans. to check: σx = 0 MPa, σy=-24.8 MPa, τxy=76.6 MPa] b) Draw the stress element at point H c) Calculate the normal and shear stresses...
The multi-material rod below has force P=3 kN applied to it. The center portion is steel, with E=207 GPa and yield strength Sy=250 MPa. The outer shell is aluminum with E=69 GPa and yield strength Sy=276 MPa. The center portion has cross-sectional area of 7.07 mm2 while the outer shell has cross-sectional area of 5.50 mm2 . The load P is applied through rigid plates (not pictured) so that the force is shared between the two materials. Note: This scenario is used...
