34. Buckling The year that the Critical Buckling force formula was derived was: A 1757 B. 1857 C. 1532 D. 1921 35. Buckling Consideration of Buckling is important in structural design because: A Buckling create high torsional forces B. Buckling is likely to increase base reactions under design loads C Buckling occurs at lower loading than the full compressive stress limits of the material D. All of the above 36. Buckling: Slenderness is generally defined as K*Wr. The term r is called radius of gyration, which is: A The square root of (VA) B. The radius of the column or brace C. I divided by the length of the member D. The amount the column deflects laterally under load 37. Buckling Slenderness is generally defined as K*Wr. The term K: A Accounts for the mass of the material 8. Accounts for the end conditions of the column or brace C Depends upon the moment of inertia of the column or brace D. None of the above 38. Buckling: If two columns have equal cross section and pin-pin end conditions, and one it taller: A The taller of the two will buckle at lower force B. They will have different k values C. Ris higher for the shorter one D. All of the above 39. Buckling: For columns with non-symmetrical cross sections? A There are no tables for these B. The critical radius of gyration will not be about the xor y axis It will buckle about the strongest of the available axes D. None of the above 40. Buckling: The force required to buckle a column is known as the critical buckling force. It is dependent upon: A Section properties of the column B. End conditions of the column C Modulus of Elasticity of the column material D. All of the above
