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 […]
What happens if the spring constant increases?
What happens if the spring constant increases? A stronger spring-with a larger value of k-will move the same mass more quickly for a smaller period. As the spring constant k increases, the period decreases. For a given mass, that means a greater acceleration so the mass will move faster and, therefore, complete its motion quicker […]
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. What state does […]
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 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 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 […]
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 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 is RMS value of AC voltage?
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 […]
What happens to kinetic energy when velocity decreases?
What happens to kinetic energy when velocity decreases? Decreases in mass cause decreases in kinetic energy due to the aforementioned positive relationship between the two. In the case of a decrease in mass and velocity, kinetic energy must decrease because both of the determining factors decreased. Does kinetic energy increase velocity? It turns out that […]
