Explain what the float is.

What is secondary compression?

can someone please help me with this? Thank you -) A short square steel structural tube is used as a compression member and is subjected to an axial load.Axial deformation is 0.004 inches. What is the load?

​Dwayne's Welding and Fabrication have decided to start a new line of workbenches to sell.​ Dwayne's designers hand him the blueprint detailing the frame of the workbench before the top and shelves are added. The specs call for 1.75​-in.×1.75​-in. square steel tubing for the frame and 0.21875​-in. thick sheet metal for the top and shelves. Dwayne found each workbench needs 579.41​" of steel tubing and 3074.09 square inches of sheet metal. For shipping​ purposes, Dwayne needs to determine the weight of the workbench. The square steel tubing for the frame weighs 0.16 pounds per inch. The sheet metal for the top and shelves weighs 0.028 pounds per square inch. What is the approximate total weight of one​ workbench? What has not been accounted for that may slightly increase the​ weight?
