How does alcohol affect reaction time while driving?

How does alcohol affect reaction time while driving? Reaction Time – Alcohol can slow reflexes, which can decrease the ability to react swiftly to changing situations. Vision – Alcohol can slow eye muscle function, alter eye movement, and alter visual perception, possibly resulting in blurred vision. Night vision and color perception also can be impaired. […]

How is martensite structure formed in steel?

How is martensite structure formed in steel? Martensite is formed in carbon steels by the rapid cooling (quenching) of the austenite form of iron at such a high rate that carbon atoms do not have time to diffuse out of the crystal structure in large enough quantities to form cementite (Fe3C). Is martensite a phase […]

What causes brittle failure?

What causes brittle failure? Brittle fractures occur when the material is subject to stresses that are smaller than the yield limit of the material. Machine design normally is based on ductile material; and the design criteria are meant to avoid plastic deformation and, in certain cases, elastic deformations. What is brittle failure? Brittle failure refers […]
