The load required to cause buckling depends on how the column is attached to its supports. the maximum or critical load for a column of length l that is pin supported at both ends is pcr=? 2eil2.

part a - maximum load

a column is made from a rectangular bar whose cross section is 5.3 cm by 9.6 cm . if the height of the column is 2 m , what is the maximum load it can support? the material has e = 200 gpa and ? y = 250 mpa .

express your answer with appropriate units to three significant figures.

part b - maximum length

a circular column with diameter 8.6 cm is to support a vertical load of 600 kn . what is the maximum length the column can have if it is pin supported at both ends? the material has e = 200 gpa . assume the material does not yield.

express your answer with appropriate units to three significant figures.

part c - required diameter

a solid circular steel column with a height of 2.6 m needs to support a vertical load of 940 kn . what is the minimum diameter required if the factor of safety for buckling is fs = 2.5 and the material has e = 200 gpa? assume the material does not yield.

express your answer with appropriate units to three significant figures.
