Euler’s buckling formula can be expressed as pcr = π2ei(kl)2 where pcr is the critical buckling load, e is the column’s young’s modulus, i is the column’s moment of inertia, and l is the column’s length. derived using a quantity called effective length, the constant k depends upon the column’s end conditions.
this problem will compare various end conditions of a slender column under compression. the studied column has a length of l = 2 meters, and its square cross-section has a side length of b = 7 centimeters. the material is a grade of steel with e = 200 gpa and σy = 500 mpa. what is the column’s critical buckling load in meganewtons (mn)? (you must provide an answer before moving to the next part.)the column's critical buckling load is mn.

Afull journal bearing has a journal diameter of 27 mm, with a unilateral tolerance of -0.028 mm. the bushing bore has a diameter of 27.028 mm and a unilateral tolerance of 0.04 mm. the l/d ratio is 0.5. the load is 1.3 kn and the journal runs at 1200 rev/min. if the average viscosity is 50 mpa-s, find the minimum film thickness, the power loss, and the side flow for the minimum clearance assembly.
