What is RMS value of AC voltage? RMS. One of the principal applications of RMS values is with alternating currents and voltages. ROOT MEAN SQUARE (RMS) VALUE. The value of an AC voltage is continually changing from zero up to the positive peak, through zero to the negative peak and back to zero again. How […]
How does alcohol affect reaction time while driving?
How does alcohol affect reaction time while driving? Reaction Time – Alcohol can slow reflexes, which can decrease the ability to react swiftly to changing situations. Vision – Alcohol can slow eye muscle function, alter eye movement, and alter visual perception, possibly resulting in blurred vision. Night vision and color perception also can be impaired. […]
How is martensite structure formed in steel?
How is martensite structure formed in steel? Martensite is formed in carbon steels by the rapid cooling (quenching) of the austenite form of iron at such a high rate that carbon atoms do not have time to diffuse out of the crystal structure in large enough quantities to form cementite (Fe3C). Is martensite a phase […]
What causes brittle failure?
What causes brittle failure? Brittle fractures occur when the material is subject to stresses that are smaller than the yield limit of the material. Machine design normally is based on ductile material; and the design criteria are meant to avoid plastic deformation and, in certain cases, elastic deformations. What is brittle failure? Brittle failure refers […]
How do you display the value axis in units of thousands?
How do you display the value axis in units of thousands? Figure 1. Create your chart as you normally would. Double-click the axis you want to scale. You should see the Format Axis dialog box. Make sure the Scale tab is displayed. (See Figure 2.) Using the Display Units drop-down list, choose Thousands. Click OK. […]
What is the pitch diameter of a thread?
What is the pitch diameter of a thread? The pitch diameter (PD, or D2) of a particular thread, internal or external, is the diameter of a cylindrical surface, axially concentric to the thread, which intersects the thread flanks at equidistant points, when viewed in a cross-sectional plane containing the axis of the thread, the distance […]
How do you evaluate mathematical expressions in Java?
How do you evaluate mathematical expressions in Java? To evaluate expressions containing variables we need to declare and initialize variables: String expression = “x=2; y=3; 3*x+2*y;”; Double result = (Double) scriptEngine. eval(expression); Assertions. assertEquals(12, result); How do you evaluate an arithmetic expression in C? Evaluation of Simple Arithmetic Expressions First determine the order in which […]
What dies CO mean?
What dies CO mean? “Co” is just an abbreviation for the word “company.” A company is an association of people working in a commercial business. This can be a limited liability company, sole proprietorship, or another structure. Abbreviating “company” as “co” does not have a specific meaning regarding a business’s legal structure.

How did architecture evolved?
How did architecture evolved? Architectural style evolved into something much more graceful through the Byzantine and Romanesque periods. It was during 527 – 1200 that the majority of architecture began to use brick instead of stone, changing forever the way that buildings would be constructed. What are the current topics in architectural research? Architecture and […]
What effect does the wind chill factor have on temperature?
What effect does the wind chill factor have on temperature? The wind chill factor describes what happens to a body when it is cold and windy outside. As wind increases, heat is carried away from the body at a faster rate, driving down both skin temperature (which can cause frostbite) and eventually the internal body […]
