Do transformers have primary and secondary coils? A transformer has two coils – a primary coil and a secondary coil. An alternating current flows in the primary coil and this induces a voltage in the secondary coil. What are the 3 types of transformers? There are three primary types of voltage transformers (VT): electromagnetic, capacitor, […]
What would cause a starter not to work?
What would cause a starter not to work? A starter malfunction can have different causes: Electrical connections faulty. Solenoid switch (engaging relay) stiff or faulty. Electric motor damaged electrically. Can a bad alternator cause slow cranking? Higher electrical demands on charging systems have increased alternator failures. A starter that’s failing may crank the engine too […]
What affects cutting speed?
What affects cutting speed? Factors affecting the calculation of cutting speed are: The material being machined (steel, brass, tool steel, plastic, wood) (see table below) The material the cutter is made from (High-Carbon Steel, high speed steel (HSS), Carbide, Ceramics, and Diamond tools) What are the effects of cutting parameters on tool life? When the […]
What is a crowned road?
What is a crowned road? Crowned roads affect how your motorcycle handles and how your tires wear. On a crowned road, that means the pavement slopes from its highest point at the left side of our lane down to its lowest point on the right edge of the lane. What are the advantages and disadvantages […]
How do you engage parking brake?
How do you engage parking brake? How does a parking brake work? Press down completely on your brake pedal. Engage your parking brake by either pulling the lever or pressing the ((P)) button. Shift your car into “park.” Release the brake pedal. Is it better to park in first gear or neutral? Do not leave […]
Is a hollow shaft stronger than a solid shaft?
Is a hollow shaft stronger than a solid shaft? Difference between the hollow shaft and solid shaft : The material at the centre is removed in the hollow shaft and spread at large radius therefore, hollow shafts are stronger than solid shafts with the same weight. The stiffness of the hollow shaft is more than […]
How does Saccharomyces cerevisiae produce ethanol?
How does Saccharomyces cerevisiae produce ethanol? S. cerevisiae is the most employed yeast for ethanol production at industrial level though ethanol is produced by an array of other yeasts, bacteria, and fungi. Ethanol has been produced from wide range of substrates such as molasses, starch based substrate, sweet sorghum cane extract, lignocellulose, and other wastes. […]
How many volts is a 3 phase?
How many volts is a 3 phase? What’s the difference between single phase and three phase? Electricity is either connected at 230 or 240 volts (single-phase, which accounts for the majority of domestic situations), or 400 and 415 Volts (three-phase). How many cycles does 3 phase current have? In a three-phase system, three circuit conductors […]
What is the best stereospecific conformation for E2 elimination?
What is the best stereospecific conformation for E2 elimination? In an E2 elimination, the new π bond is formed by overlap of the C-H σ bond with the C-X σ* anti-bonding orbital. The two orbitals have to lie in the same plane for best overlap. E2 elimination takes place from the anti-periplanar conformation, as this […]
What causes an engine to knock?
What causes an engine to knock? The knocking sound often occurs when the air-fuel mixture is incorrect, which causes the fuel to burn in uneven pockets rather than uniform bursts. Left untreated, it can cause damage to the piston and cylinder wall. A knocking sound can also be caused by a lack of lubrication in […]
