How do you calculate Brinell hardness number?
How do you calculate Brinell hardness number? P = applied load in kilogram-force (kgf) D = diameter of indenter (mm) d = diameter of indentation (mm) Brinell hardness is sometimes quoted in megapascals; the Brinell hardness number is multiplied by the acceleration due to gravity, 9.80665 m/s2, to convert it to megapascals. How do you […]

Is a replay attack a type of man in the middle attack?
Is a replay attack a type of man in the middle attack? This is carried out either by the originator or by an adversary who intercepts the data and re-transmits it, possibly as part of a spoofing attack by IP packet substitution. This is one of the lower-tier versions of a man-in-the-middle attack. Replay attacks […]
How do you calculate module efficiency?
How do you calculate module efficiency? To calculate the solar panel efficiency, you need to divide the Wattage per unit area (Pmax/total area in sq. m.) of the solar module by the STC Irradiance value (1000W/sq. m.). What does module efficiency mean? The Module Efficiency rating on your solar panel’s spec sheet measures the percentage […]
What causes no spark from coil?
What causes no spark from coil? Loss of spark is caused by anything that prevents coil voltage from jumping the electrode gap at the end of the spark plug. This includes worn, fouled or damaged spark plugs, bad plug wires or a cracked distributor cap. Can a bad ignition coil cause no spark? A Bad […]
What are the three 3 basic steps of the photolithography process?
What are the three 3 basic steps of the photolithography process? Photolithography uses three basic process steps to transfer a pattern from a mask to a wafer: coat, develop, expose. The pattern is transferred into the wafer’s surface layer during a subsequent process. Which of the following best describes the photolithography process? Which of the […]
