How many edges does a minimum spanning tree for G have? Spanning tree has n-1 edges, where n is the number of nodes (vertices). From a complete graph, by removing maximum e – n + 1 edges, we can construct a spanning tree. A complete graph can have maximum nn-2 number of spanning trees. Does […]

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 […]
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 […]
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 […]
How does an ABS speed sensor work?
How does an ABS speed sensor work? The sensors work with the toothed tone wheels to monitor and provide the anti-lock brake module (ABM) with wheel speed information. The result is an alternating current (AC) voltage that is generated in the speed sensor coil by magnetic lines of force fluctuating as the tone wheel passes […]
How do you calculate nominal interest compounded monthly?
How do you calculate nominal interest compounded monthly? For example: assume you deposit 100 dollars in a bank account and the bank pays you 6% interest compounded monthly. This means the nominal annual interest rate is 6%, interest is compounded each month (12 times per year) with the rate of 6/12 = 0.005 per month, […]
