Concept explainers

Buckling of columns

The column is described as a vertical member of the structure that carries an axial compressive load, and buckling is a lateral deformation of the column under the application of load.

Question

An A-36 steel bolt (AB) is used to snugly clamp a 6061-T6 aluminum sleeve
between two rigid platens E and F, as shown below. The bolt has a solid, circular cross section
with a diameter d = 61 mm and a thread pitch
of 1 mm. The sleeve has a hollow circular
cross section with an outer diameter do 250
mm and a wall thickness tw = 15 mm. The
nut is then tightened 34 of a turn, which
induces stresses in both the bolt and the
sleeve. Assume Es = 200 GPa for steel and
Ea 68.9 GPa for aluminum.

Required information For a bolted assembly with six bolts, the stiffness of each bolt is kb 2 Mibf/in and the stiffness of the members is km = 13 Mlbf/in per bolt. An external load of 80 kips is applied to the entire joint. Assume the load is equally distributed to all the bolts. It has been determined to use 1/2 in-13 UNC grade 8 bolts with rolled threads. It is desired to find the range of torque that a mechanic could apply to initially preload the bolts without expecting failure once the joint is loaded. Assume a torque coefficient of K = 0.2. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Determine the maximum bolt preload that can be applied without exceeding the proof strength of the bolts once the load is applied. The maximum bolt preload that can be applied is Ibf.
