How is mean time between failure calculated MTBF? To calculate MTBF, divide the total number of operational hours in a period by the number of failures that occurred in that period. MTBF is usually measured in hours. For example, an asset may have been operational for 1,000 hours in a year. Therefore, the MTBF for […]
What is the difference between boring and reaming?
What is the difference between boring and reaming? Boring is performed to enlarge an existing hole or to convert a cylindrical hole into a taper hole. Reaming is carried out to highly finish the surfaces of a hole. Its purpose is to improve dimensional accuracy and tolerance. What are the differences between boring on a […]
What race is most affected by lactose intolerance?
What race is most affected by lactose intolerance? Lactose intolerance in adulthood is most prevalent in people of East Asian descent, with 70 to 100 percent of people affected in these communities. Lactose intolerance is also very common in people of West African, Arab, Jewish, Greek, and Italian descent. Why is lactose intolerance becoming more […]

Where is robotics used?
Where is robotics used? Robots are widely used in manufacturing, assembly, packing and packaging, mining, transport, earth and space exploration, surgery, weaponry, laboratory research, safety, and the mass production of consumer and industrial goods. What is robotics in simple words? Robotics is the intersection of science, engineering and technology that produces machines, called robots, that […]
How does an infrared sensor work?
How does an infrared sensor work? Active infrared sensors both emit and detect infrared radiation. Active IR sensors have two parts: a light emitting diode (LED) and a receiver. When an object comes close to the sensor, the infrared light from the LED reflects off of the object and is detected by the receiver. What […]
What do you do when you see a red lighted buoy with the number 6?

Where are power factor correction capacitors installed?
Where are power factor correction capacitors installed? Capacitors are connected directly to the terminals of inductive circuit. Individual compensation should be considered when the power of the motor is significant with respect to the declared power requirement (kVA) of the installation. How does adding a capacitor improve power factor? Power factor correction capacitors increase system […]
