What are the advantages of light gauge steel construction over wood light frame?
What are the advantages of light gauge steel construction over wood light frame? Structural steel components are lighter and stronger than weight-bearing wood or concrete products. A typical weight-bearing steel fabrication is 30% to 50% lighter than a wooden equivalent. This makes steel frame construction far stronger and more durable than traditional wood framed alternatives. […]

How do you calculate mean time between failures?
How do you calculate mean time between failures? To calculate MTBF, divide the total number of operational hours in a period by the number of failures that occurred in that period. MTBF is usually measured in hours. For example, an asset may have been operational for 1,000 hours in a year. Over the course of […]
Why does super glue not stick to the inside of the tube?
Why does super glue not stick to the inside of the tube? Superglue will not stick to the tube as the inside contains oxygen, in the form of air, but excludes water. Thus oxygen inhibits the process of polymerisation while water catalyses the reaction. This explains why a thin layer of glue is ideal to […]

Where does the piston begin in the four-stroke cycle?
Where does the piston begin in the four-stroke cycle? The engine cycle begins with the intake stroke as the piston is pulled towards the crankshaft (to the left in the figure). The intake valve is open, and fuel and air are drawn past the valve and into the combustion chamber and cylinder from the intake […]
