How do you measure strain with strain gauge? Therefore, to measure the strain, you have to accurately measure very small changes in resistance. For example, suppose a test specimen undergoes a strain of 500 me. A strain gage with a GF of 2 exhibits a change in electrical resistance of only 2 (500 x 10-6) […]
What is preventive and predictive maintenance?
What is preventive and predictive maintenance? Preventive maintenance (PM) is work that is scheduled based on calendar time, asset runtime, or some other period of time. Predictive maintenance (PdM) is work that is scheduled as-needed based on real time conditions of assets. What is the component required for predictive maintenance? Some of the main components […]
What happens when the base current of a transistor is increased?
What happens when the base current of a transistor is increased? Fundamentally, it is the voltage across the B-E junction that determines the amount of current flowing through it. An increase in this voltage results in increased currents in both the base and the collector, and indeed, an increase in base current causes an increase […]
Which are the mixture used to make acetylene gas?
Which are the mixture used to make acetylene gas? It is created by mixing lime and coke in a blast furnace. The product manufactured is calcium carbide. It is reacted with water to create acetylene gas, and this reaction can be easily formulated as CaC2 + 2H2O → C2H2 + Ca (OH)2. Acetylene, calcium hydroxide […]

What does it mean when the temperature warning light comes on?
What does it mean when the temperature warning light comes on? When the coolant temperature warning light goes on, the engine is seriously overheated, which can be caused by overheating, lack of cooling water or a cooling system that is having trouble. At this point, you need to park your car in a safe area […]
Can I build house without pillar?
What is the name of piping system adopted in plumbing of drainage?
What is the name of piping system adopted in plumbing of drainage? Single Stack System This system of pipes carries waste water from the wash basin, bathrooms, sinks and the foul matters from the water closets. This is connected to a final single pipe. Is a drain from the two or three fixtures connected to […]
Which refrigerant is used in Vapour compression cycle?
Which refrigerant is used in Vapour compression cycle? The most common include ammonia, Freon (and other chlorofluorocarbon refrigerants, aka CFCs), and HFC-134a (a non-toxic hydrofluorocarbon). The Vapor-Compression Refrigeration Cycle is comprised of four steps. The conceptual figure of the process shows the PV changes during each part. Which fluid can be used in Vapour refrigeration? […]
What are the desirable properties of hydraulic fluid?
What are the desirable properties of hydraulic fluid? Characteristics of a Good Hydraulic Fluid Viscosity. Viscosity is a measure of a hydraulic fluid’s resistance to flow. Compressibility. Compressibility is a measure of the amount of volume reduction due to pressure. Wear Resistance. Oxidation Stability. Thermal Stability. Filterability. Rust and Corrosion Protection. Foam Resistance.
