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 […]
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 […]
Does a programmer needs to understand sequencing to determine whether the order of steps will affect the outcome of the program?
Does a programmer needs to understand sequencing to determine whether the order of steps will affect the outcome of the program? What is the purpose of an algorithm? A computer reads a sequence from top to bottom and left to right. A programmer needs to understand sequencing to determine whether the order of steps will […]
What does the Charpy test determine?
What does the Charpy test determine? The Charpy impact test, also known as the Charpy V-notch test, is a high strain-rate test that involves striking a standard notched specimen with a controlled weight pendulum swung from a set height. The impact test helps measure the amount of energy absorbed by the specimen during fracture. What […]
