What is ferritic and austenitic steel? Ferritic stainless steels are magnetic, while austenitic stainless steels in the annealed condition are not. When the austenite converts to martensite, strength increases, ductility increases, and the structure becomes magnetic. What is ferrite stabilizer? The ferrite stabilizers are chromium, silicon, molyb- denum and columbium. It is the balance between […]
What is the main general purpose of negative feedback?
What is the main general purpose of negative feedback? Negative feedback occurs when a system’s output acts to reduce or dampen the processes that lead to the output of that system, resulting in less output. In general, negative feedback loops allow systems to self-stabilize. Negative feedback is a vital control mechanism for the body’s homeostasis. […]
What is the Vmax in the absence of inhibitor?
What is environment with reference?
What is environment with reference? 1 : the circumstances, objects, or conditions by which one is surrounded. 2a : the complex of physical, chemical, and biotic factors (such as climate, soil, and living things) that act upon an organism or an ecological community and ultimately determine its form and survival. What do you understand by […]
How many edges does a minimum spanning tree for G have?
Is it easy to replace a rear derailleur?
Is it easy to replace a rear derailleur? Believe it or not, it’s not difficult to replace the rear derailleur yourself. Unscrew the derailleur from the derailleur hanger by inserting a hex wrench and turning counter-clockwise. The derailleur will now come away from the hanger. Remove the derailleur cable by loosening the hex bolt on […]
How do you identify process improvements?
How do you identify process improvements? 4 Steps for an Effective Business Process Improvement Cycle Identify the need for change: The first step in the BPI process is to identify the need for change. Analyze current process: Once you have decided which process you are going to improve you need analyze the current procedure. Obtain […]
Why is it important to provide a means of venting gases from the mold cavity?
Why is it important to provide a means of venting gases from the mold cavity? Proper mold venting is essential for producing quality parts. During the molding process, the air contained in the mold needs a way to escape, otherwise the melt will compress and trap that air in the cavity. What is venting in […]
What does the stator do in an alternator?
What does the stator do in an alternator? The stator is fixed to the shell of the alternator, and does not turn. As the rotor turns within the stator windings, the magnetic field of the rotor sweeps through the stator windings, producing an electrical current in the windings. Because of the rotation of the rotor, […]
What are the strokes of a 4 stroke cycle?
What are the strokes of a 4 stroke cycle? An internal-combustion engine goes through four strokes: intake, compression, combustion (power), and exhaust. How many of the 4 strokes turn the engine? 2 How many times for every 4 strokes in a 4 stroke engine cycle does the crankshaft rotate? A 4-stroke engine fires once every […]
