What is load cell working principle? Load cell is a sensor or a transducer that converts a load or force acting on it into an electronic signal. Resistive load cells work on the principle of piezo-resistivity. When a load/force/stress is applied to the sensor, it changes its resistance. Where is load cell used? A load […]
What is the first law of thermodynamics and how does it relate to energy use?
What is the first law of thermodynamics and how does it relate to energy use? What is the first law of thermodynamics and how does it relate to energy use? The first law of thermodynamics states that energy is conserved in chemical processes. This amount of energy that must be lost to the surroundings for […]
What is uniaxial tensile test?
What is uniaxial tensile test? The uniaxial tension test is one of the most commonly used tests to determine important material parameters such as Young’s modulus, yield strength, ultimate strength, elongation at break, Poisson’s ratio, and Lankford coefficients (r-values). Tensile testing, monotonic to failure (i.e. ASTM D638, ISO 527 etc.) Why is it important to […]
How many atoms are centered on the 100 plane for the FCC crystal structure?
How many atoms are centered on the 100 plane for the FCC crystal structure? 4 atoms What are the 3 types of unit cells? A unit cell is the smallest repeating portion of a crystal lattice. Unit cells occur in many different varieties. As one example, the cubic crystal system is composed of three different […]
Should there be grease on ABS sensor?
What did the Clean Air Act authorize the EPA to do?
What did the Clean Air Act authorize the EPA to do? 42 U.S.C. Among other things, this law authorizes EPA to establish National Ambient Air Quality Standards (NAAQS) to protect public health and public welfare and to regulate emissions of hazardous air pollutants. What was the Clean Air Act and why was it so important? […]
What is evaporating temperature in refrigeration?
What is evaporating temperature in refrigeration? As its name implies, refrigerant in the evaporator “evaporates”. Upon entering the evaporator, the liquid refrigerant’s temperature is between 40° and 50°F; and without changing its temperature; it absorbs heat as it changes state from a liquid to a vapor. What controls the flow of refrigerant to the evaporator? […]
Is Unix a time-sharing operating system?
Is Unix a time-sharing operating system? IIX is a multi-processing and multi-user timesharing operating system. UNIX provides a great range of programs and services that have made the UNIX system environment popular among users. What is a UNIX based operating system? What is UNIX? UNIX is an operating system which was first developed in the […]
How did the engineers solve the problem?
How did the engineers solve the problem? Engineers will often use reverse-engineering to solve problems. For example, by taking things apart to determine an issue, finding a solution and then putting the object back together again. Engineers know how things work, and so they constantly analyse things and discover how they work. How can we […]
