An aluminum column with a length of L and a rectangular cross-section has a fixed end B and supports a centric load at A. Two smooth and rounded fixed plates restrain end a from moving in one of the vertical planes of symmetry of the column but allow it to move in the other plane. (a) Determine the ratio a/b of the two sides of the cross section corresponding to the most efficient design against buckling. (b) Design the most efficient cross section for the column, knowing that L = 20in., E=10.1 x 10^6 psi, P = 5kips, and a factor of safety of 2.5 is required. Now, replace the pinned boundary condition on top with a fixed boundary condition. You otherwise leave all other aspects of the problem unchanged.

just final answer A rigid component ABC is supported by a pin-connected member (1). The member has a rectangular cross-section with dimensions of 54 mm and 48 mm. The elasticity modulus of the material is 169 GPa. If L1=2421 mm, L2=1226 mm, L3=2272 mm, and L4=2072 mm; Determine the maximum normal stress (MPa) in member (1) without buckling.
Four axially loaded members are shown below. All members have the same value for E (Young’s modulus) and for ν (Poisson’s ratio).
A frame ABC consists of a horizontal beam BC which is supported by a round solid rod AB inclined at a 50° angle, as shown below. The ends of the rod AB are flattened to make pin connections at A and B. A vertical load of 5,000 N is acting at the mid-length of the beam. The rod material is a steel with modulus equal to 207 GPa and yield strength of 220 MPa. (a) Using a factor of safety of2.5, determine the diameter of the rod AB. (b) If a clevis joint is used at the pin connection at B, design the pin diameter so that it does not fail in shear. The tensile yield strength of the pin material is 300 MPa. Use a factor of safety between 1.5 and 2.5. 5,000 N В C 5 m 3 m 50° A
