Using a minimum amount of M112, how many packages are required to cut a steel shaft 24" in circumference?

what is the equation for finding toughness?

Determine the number of reinforcing steel bars in pieces (commercial length) and tie wire in kilogram required in 4m height reinforced concrete wall (THK = 6”) with a length of 10 meters.

​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?
