Axial compressive load

Select the lightest W shaped for a column subjected to an axial compressive load of 6000 kips. The unbraced length of the column is 15ft and the ends are fixed/pinned.

Axial compressive load

Design a square or rectangular (2-in. nominal increments) pin-connected southern pine column (S4S). The unbraced length of the column is 16ft. The column is to support an axial compressive load of 60,000 lbs.

A timber of uniform cross section with a mass of 90 kg

A timber of uniform cross section with a mass of 90 kg is hinged at its lower end and held at angle of 60 degrees with the horizontal by a rod attached as shown in (attached figure 4-6) A cylinder which has a mass of 30 kg is placed between the timber and the wall. 1) What are the horizontal and vertical components of the reaction at A? 2) What is the force between the cylinder and the timber? N.B. Show all detail

How much force can be given before this tube bends

I have a 3x3 in tube ASTM A500 Steel 1/4" thick. I need to know how much force can be given on both ends with two pivot points a certain length in from the ends before the tube bends.
