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.

Asolid cylinder is concentric with a straight pipe. the cylinder is 0.5 m long and has an outside diameter of 8 cm. the pipe has an inside diameter of 8.5 cm. the annulus between the cylinder ad the pipe contains stationary oil. the oil has a specific gravity of 0.92 and a kinematic viscosity of 5.57 x 10-4 m2/s. most nearly, what is the force needed to move the cylinder along the pipe at a constant velocity of 1 m/s?

Acountershaft is supported by two tapered roller bearings using indirect mounting. the radial bearing loads are 1120 lb for the left-hand bearing and 2190 lb for the right-hand bearing. the shaft rotates at 400 rpm and is to have an l10 life of 40,000 hours and an application factor of 1.4. assume ka2k 15, and find the required radial rating of each bearing
