How do you use a multimeter step by step? Step 2 To begin, make sure no current is running through the circuit or component you want to test. Switch it off, unplug it from the wall, and remove any batteries. Plug the black probe into the COM port on your multimeter. Plug the red probe […]
Which devices can be used for the purpose of lockout?
Which devices can be used for the purpose of lockout? Lockout device: Any device that uses positive means, such as a lock, blank flanges and bolted slip blinds, to hold an energy-isolating device in a safe position, thereby preventing the energizing of machinery or equipment. What are double block and bleed valves used for? Double […]
What is relational algebra explain with example?
What is relational algebra explain with example? RELATIONAL ALGEBRA is a widely used procedural query language. It collects instances of relations as input and gives occurrences of relations as output. It uses various operations to perform this action. The output of these operations is a new relation, which might be formed from one or more […]
How is a 1 1 ratio achieved using a planetary gear set?
How is a 1 1 ratio achieved using a planetary gear set? Most automatic transmissions have a 1:1 ratio in third gear. If both sun gears turn in the same direction, the planet gears lockup because they can only spin in opposite directions. This locks the ring gear to the planets and causes everything to […]
How are electromagnets similar to generators?
How are electromagnets similar to generators? Generators are based on the connection between magnetism, motion and electricity. Generators typically use an electromagnet, which is created by electricity and a rapidly spinning turbine to produce massive amounts of current. The standard generator contains a group of insulated wire coils in the shape of a cylinder. How […]
What are the advantages and disadvantages of using CMM?
What are the advantages and disadvantages of using CMM? 3) Accurate dimensions can be obtained just by knowing the coordinates and distance between the two reference points. 4) Robustness against external force and error accumulation. Disadvantages: 1) The Coordinate measuring machines are very costly. 2) The CMMs are less portable. What are the advantages and […]
What is the relationship between technology and engineering?
What is the relationship between technology and engineering? Engineering is defined as a systematic and iterative approach to designing objects, processes, and systems to meet human needs and wants. Technology is defined as any modification of the natural or designed world developed to fulfill human needs or desires. How does science technology and engineering work […]
How do you find the voltage across an inductor?
How do you find the voltage across an inductor? You can calculate voltage across inductance by the formula V=L*(di/dt) where L is the inductance and di/dt is the derivative of current, change in current. What is the voltage across an inductor? What is the voltage across the inductor? The inductor equation tells us: v = […]
When should you always engage parking brake?
When should you always engage parking brake? You should use your emergency brake every time you park. It doesn’t matter if you’re on a hill or a flat parking lot, whether you drive an automatic or manual transmission, or whether the weather is pleasant or inclement. As the name suggests, you should also use your […]
Why should climate change stop?
Why should climate change stop? “Climate change exerts a de-stabilizing influence on an already-unstable world,” says Peter deMenocal, a climate scientist with Columbia University. “It adds a fundamental insecurity to people’s lives and livelihoods, from small island nations to the most developed nations in the world. Why is climate change so important? Climate affects nearly […]
