How do you calculate chip thickness ratio? Chip Thickness ratio is defined as the thickness of metal before cutting to the thickness of metal after cutting. Then, r= t1 / t2. Whenever there is high cutting ratio , it means the cutting action is good. Which of the following is correct equation for shear force […]
What is the need for anti aliasing filter prior to down sampling?
What is the need for anti aliasing filter prior to down sampling? Answer. An “anti – aliasing” or “anti-imaging” channel / filter is set before the A-to-D converter, to counteract / prevent flag frequencies more noteworthy than a large portion of the testing rate from being digitized, which would create pictures at undesirable frequencies. What […]
Is work a property?
What electrical term best describes the opposition to current flow?
What electrical term best describes the opposition to current flow? Current tends to move through the conductors with some degree of friction, or opposition to motion. This opposition to motion is more properly called resistance. The amount of current in a circuit depends on the amount of voltage and the amount of resistance in the […]
What are the main components of a comfortable and healthy building environment?

The following components were included: healthy, sustainable air; healthy, sustainable thermal control; healthy, sustainable light; workplace ergonomics and environmental quality; access to the natural environment; and. land use and transportation. What is needed to be considered a LEED construction project? LEED Certification Minimum […]
What is the 6 disconnect rule?
What is the 6 disconnect rule? The rule is six disconnecting means for each service, not six service disconnecting means per building. If the building has two services, you can have a total of 12 service disconnects (six disconnects per service). What does service disconnect mean? Electrical disconnects are switches that isolate all wiring in […]
Is it better to sleep in silence or with noise?
Is it better to sleep in silence or with noise? No, really. While it may seem a little hard to believe, perfect silence can keep some people from dropping off and enjoying a good night’s sleep. Sounds of this sort work by creating a level of steady, consistent background noise that can help to mask […]
What are the graduations on the sleeve of a metric micrometer?
What are the graduations on the sleeve of a metric micrometer? The thimble has 50 graduations, each being 0.01 millimetre (one-hundredth of a millimetre). Thus, the reading is given by the number of millimetre divisions visible on the scale of the sleeve plus the particular division on the thimble which coincides with the axial line […]
What are the magnetic properties of materials?
What are the magnetic properties of materials? 5 Magnetic Properties of Materials Property 1: Intensity of magnetisation (I) Property 2: Magnetic Field (H) or Magnetic intensity. Property 3: Magnetic susceptibility. Property 5: Coercivity. What are domains in magnetic materials? A domain is a region inside of a material where groups of magnetic moments naturally align […]
What is ideal voltage source and ideal current source?
What is ideal voltage source and ideal current source? An ideal voltage source provides no energy when it is loaded by an open circuit (i.e. an infinite impedance), but approaches infinite energy and current when the load resistance approaches zero (a short circuit). An ideal current source has an infinite output impedance in parallel with […]
