What are the two basic methods of arc shielding? What are the two basic methods of arc shielding? (1) Shielding gas, such as argon and helium; and (2) flux, which covers the welding operation and protects the molten pool from the atmosphere. Why is the shielded metal arc welding process difficult to automate? Why is […]
What is the relationship between voltage and temperature?
What is the relationship between voltage and temperature? Voltage is directly proportional to resistant (V=IR) and resistance increases with temperature due to increased vibrations of the molecules inside the conductor. Therefore voltage increases as temperature increases. What is the relationship between voltage and resistance? Ohm’s law defines the relationship between the voltage, current, and resistance […]

What is the process of making glass?
What is the process of making glass? Making glass is a fairly straightforward process. In a commercial glass plant, sand is mixed with recycled glass, sodium carbonate, and calcium carbonate. These substances are then heated in a furnace. Once in a liquid state, it is poured into molds to shape, or poured on a flat […]
What is differential input voltage?
What is differential input voltage? The differential input voltage is the maximum voltage that can be supplied to the +Input (Non-inverting input) and -Input (Inverting input) pins without causing damage or degrading IC characteristics. Why is differential amplifier needed? Differential amplifiers are used mainly to suppress noise. Noise is generated in the wires and cables, […]
Why is it important to determine the impacts of technology on society?
Why is it important to determine the impacts of technology on society? Technology affects the way individuals communicate, learn, and think. It helps society and determines how people interact with each other on a daily basis. Technology plays an important role in society today. It has positive and negative effects on the world and it […]
What will adding an iron core to the inside of the electromagnet do to the magnet?
What will adding an iron core to the inside of the electromagnet do to the magnet? An iron core makes a temporary electromagnet. It loses its magnetism as soon as the switch is opened and the current is switched off. A steel core makes a more permanent magnet. It does not lose its magnetism quickly […]
What is aerobic pond?
What is aerobic pond? A lagoon that forms the third treatment stage in waste stabilization ponds (WSP). It is a shallow pond with large surface area to enable light penetration and oxygenation by wind mixing. The effluent is generally free of pathogens but rich in nutrients and can be reused for fertigation or aquaculture. What […]
What are hydraulic shears used for?
What are hydraulic shears used for? Hydraulic shears are used in high volume metal fabricating operations that require the ability to accurately and quickly cut and score sheets of metal. Hydraulic shears, contrary to their name, look nothing at all like shears. How does a hydraulic shear work? With shear machining, the tool’s cutting edge […]
