Response: The provision in question, 29 CFR 1910.303(g)(2)(i), generally requires “live parts of electric equipment operating at 50 volts or more” to be “guarded against accidental contact by use of approved cabinets or other forms of approved enclosures” or […]
Why silicon is most widely used semiconductor material?
Why silicon is most widely used semiconductor material? Each Silicon atom is combined with four neighboring silicon atoms by four bonds. Silicon, a very common element, is used as the raw material of semiconductors because of its stable structure. Purification of Silicon consumes large amounts of power. Why silicon is most widely used? Silicon is […]
How do you do input and output tables?
How do you do input and output tables? The rule for the input-output table below is: add 1.5 to each input number to find its corresponding output number. Use this rule to find the corresponding output numbers. To find each output number, add 1.5 to each input number. Then, write that output number in the […]
What causes residual stress in welding?
What causes residual stress in welding? Welding residual stresses are caused by differential thermal expansion and contraction of the weld metal and parent material. This is illustrated in Fig. 7.5 for longitudinal residual stresses (transverse residual stresses are also induced, although these generally have compressive and tensile zones within the weld). What are residual stresses […]
What does application of centrifugal air compressor lead to?
What does application of centrifugal air compressor lead to? A centrifugal compressor imparts kinetic energy into the airstream by increasing the velocity of the air using a rotating element and then converts this kinetic energy into potential energy in the form of pressure. How do centrifugal compressors work? A centrifugal compressor is a type of […]
What is collimation method?
What is collimation method? The collimation method is the height-of-instrument method of leveling whereby fore-and-aft readings are made on a leveling staff by an instrument placed intermediately so that the rise or fall between the fore station and the back station is shown by a change in the staff reading. See Also: rise and fall. […]
What is the process of logistics?
What is the process of logistics? Logistics is the process of planning and executing the efficient transportation and storage of goods from the point of origin to the point of consumption. The goal of logistics is to meet customer requirements in a timely, cost-effective manner. FedEx, UPS and DHL are well-known logistics providers. What is […]

Why do geostationary satellites have to be above the equator?
Why do geostationary satellites have to be above the equator? It is always directly over the same place on the Earth’s surface. Satellites in geostationary orbit rotate with the Earth directly above the equator, continuously staying above the same spot. This position allows satellites to observe weather and other phenomena that vary on short timescales. […]
