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 […]
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 […]
Which of the following causes stress concentration?
Which of the following causes stress concentration? Stress concentrations occur when there are irregularities in the geometry or material of a structural component that cause an interruption to the flow of stress. This arises from such details as holes, grooves, notches and fillets. Stress concentrations may also occur from accidental damage such as nicks and […]
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 […]
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 […]

What are power requirements?
What are power requirements? There are two types of power requirements based on a number of factors, least of which is the size of the overall project. There is power as in the amount of computing power, as in the amount of microprocessors and their speed, and the amount of peak watts from the computing […]
What is the difference between a blind rivet and a pop rivet?
What is the difference between a blind rivet and a pop rivet? Blind rivets, also commonly referred to as POP Rivets, are mainly used in applications where there is no access to the rear (blind side) of the joint. Rivets have a two-piece construction; one is called the rivet body, shell, or hat and another […]
