What are the advantages of light gauge steel construction over wood light frame? Structural steel components are lighter and stronger than weight-bearing wood or concrete products. A typical weight-bearing steel fabrication is 30% to 50% lighter than a wooden equivalent. This makes steel frame construction far stronger and more durable than traditional wood framed alternatives. […]
What is maintenance and its type?
What is maintenance and its type? The work carried out on equipment in order to avoid its breakdown or malfunction. It is a regular and routine action taken on equipment in order to prevent its breakdown. Maintenance, including tests, measurements, adjustments, parts replacement, and cleaning, performed specifically to prevent faults from occurring. Why maintenance is […]
Does speed affect torque?
Does speed affect torque? Torque is the rotational equivalence of linear force. Speed measures the distance covered in unit time. The relation between torque and speed are inversely proportional to each other. The torque of a rotating object can be mathematically written as the ratio of power and angular velocity. Does more torque mean more […]
Where is the best place to look for information on a motor?
Where is the best place to look for information on a motor? Answer: Motor Connections– When connecting motors, several factors should be considered, such as horsepower, service factor (SF), marked temperature rise, voltage, full-load current rating, and National Electrical Manufacturers Association (NEMA) Code letter. This information is found on the motor nameplate. What is the […]
What is diode current equation?
What is diode current equation? Diode current equation expresses the relationship between the current flowing through the diode as a function of the voltage applied across it. Mathematically it is given as. Where, I is the current flowing through the diode. What is the difference between pn junction diode and solar cell? The solar cell […]
How do you calculate the maximum efficiency of a heat engine?
How do you calculate the maximum efficiency of a heat engine? The maximum theoretical efficiency of a heat engine (which no engine ever attains) is equal to the temperature difference between the hot and cold ends divided by the temperature at the hot end, each expressed in absolute temperature (Kelvin). What is the maximum efficiency […]
Which property will be the same no matter how much matter is present?
How much time does it take to charge a capacitor?
How much time does it take to charge a capacitor? If a resistor is connected in series with the capacitor forming an RC circuit, the capacitor will charge up gradually through the resistor until the voltage across it reaches that of the supply voltage. The time required for the capacitor to be fully charge is […]
How does a Rankine cycle work?
How does a Rankine cycle work? The Rankine cycle or Rankine Vapor Cycle is the process widely used by power plants such as coal-fired power plants or nuclear reactors. In this mechanism, a fuel is used to produce heat within a boiler, converting water into steam which then expands through a turbine producing useful work. […]
What does porcelain enamel mean?
What does porcelain enamel mean? Porcelain enamel, a thin layer of ceramic or glass applied to a substrate of metal, is used to protect surfaces from chemical attack and physical damage, modify the structural characteristics of the substrate, and improve the appearance of the product. What does vitreous enamel mean? : a fired-on opaque glassy […]
