What factors influence the level of hardness?
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? […]

Why should you visually check for motorcycles when changing lanes?
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?
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 […]
Can 2 remote control cars same frequency?
Can 2 remote control cars same frequency? If you don’t plan to run your RC cars, trucks, boats, or aircraft alongside other radio controlled vehicles, it doesn’t really matter which frequency they use. However, running two 27MHz or two 49MHz RC cars near each other will usually result in interference—crosstalk. The radio signals get mixed […]
Who wins the tug of war with what net force?
What percentage of C 14 remains after 3 half lives?
Which one is the best example of law of conservation of mass?
Which one is the best example of law of conservation of mass? The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases equals the original mass of the charcoal and the oxygen when it […]
