What is WEP vs WPA? WEP stands for Wired Equivalent Privacy, and WPA stands for Wireless Protected Access. Using some encryption is always better than using none, but WEP is the least secure of these standards, and you should not use it if you can avoid it. WPA2 is the most secure of the three. […]
What kind of microscope would be used to study a while or opaque object?
What kind of microscope would be used to study a while or opaque object? The stereo microscope, also called a dissecting microscope, provides magnification of up to 300 times. These binocular microscopes are used to look at opaque objects or objects that are too large to be viewed with a compound microscope, since they do […]
What is the principle of nuclear magnetic resonance imaging?
What is the principle of nuclear magnetic resonance imaging? At resonance, the nuclear magnets tend to spin in phase with one another and a portion of the nuclear magnets are ele- vated to the excited state with their magnetic moments opposed to the applied magnetic field. In this example, a net magnetization is produced in […]
Why is my computer always updating when I shut down?
Why is my computer always updating when I shut down? This could be because of your “Windows Update” settings. If it is configured to run frequently (daily), then the available updates downloaded in the temp location and will get installed when you shutting down your machine. What happens when you turn off your computer when […]
What problems may result by using an electrode at too low a current setting?
What problems may result by using an electrode at too low a current setting? What problems may result by using an electrode at too low a current setting? poor fusion and poor arc stability. Why is it usually better to make a weld in the flat position? This flat horizontal position allows for the maximum […]
Why do mechanical and physical properties depend on the density of PM parts?
Why do mechanical and physical properties depend on the density of PM parts? Explain why the mechanical and physical properties depend on their density. Mechanical properties rely on their density to maximize metal particle contact and cohesion which affects a metal’s strength, ductility, elastic modulus, and toughness. Describe the relative advantage of cold isostatic pressing. […]
What does a pitot static tube measure?
What does a pitot static tube measure? Basically, a pitot tube is used in wind tunnel experiments and on airplanes to measure flow speed. It’s a slender tube that has two holes on it. The side hole measures the static pressure. By measuring the difference between these pressures, you get the dynamic pressure, which can […]
What is heat rate in powerplant?
What is heat rate in powerplant? Heat rate is one measure of the efficiency of electrical generators/power plants that convert a fuel into heat and into electricity. The heat rate is the amount of energy used by an electrical generator/power plant to generate one kilowatthour (kWh) of electricity. If the heat rate is 7,500 Btu, […]
How do you calculate the pitch diameter of a spur gear?
How do you find the angular acceleration of a rod?
How do you find the angular acceleration of a rod? 3 Answers Sum of the forces on body equals mass times acceleration at the center of gravity. ∑i→Fi=m→aC. Ax=maxAy−mg=may. Sum of torques about center of gravity equals moment of inertia times angular acceleration. ∑i(→Mi+(→ri−→rC)×→Fi)=IC→α Acceleration of point A must be zero. →aA=→aC+→α×(→rA−→rC)+→ω×(→vA−→vC) How do you […]
