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? 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 […]

Should there be grease on ABS sensor? Grease = normal. The ABS sensor lives in grease and hovers right over the top of a toothed gear on the edge of a birfield packed in a chamber 3/4 full of molly grease. How does a speed sensor work? 11.40) The speed sensor uses the variable reluctance […]

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 […]

What is the federal E-Rate program? The universal service Schools and Libraries Program, commonly known as “E-rate,” provides discounts of up to 90 percent to help eligible schools and libraries in the United States obtain affordable telecommunications and internet access. How does the E-Rate program work? The Schools and Libraries (E-rate) Program provides discounts to […]

What factors influence the level of hardness? The greater the resistance capacity to deformation it is, the higher the hardness value it will have. There are many factors effect specimen’s hardness value, including its chemical component, organization structure, treatment process, and outer environment. What does hardness testing determine? What is the definition of hardness testing? […]

What is the compression ratio of axial flow compressor? approximately 1.25 to 1 What is a stage in axial flow compressor? The Axial Flow Compressor The compressor is a multistage unit as the amount of pressure increase by each stage is small; a stage consists of a row of rotating blades followed by a row […]

Why should you visually check for motorcycles when changing lanes? When changing lanes or entering a major thoroughfare, make a visual check for motorcycles, in addition to using your mirrors. Motorcycles are small and this allows them to tuck easily into the blind spots of other vehicles. Motorcycles are entitled to the same full lane […]

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 […]
