What is stress and strain in materials? Stress is the force applied to a material, divided by the material’s cross-sectional area. σ = stress (N/m2, Pa) F = force (N) A0 = original cross-sectional area (m2) Strain is the deformation or displacement of material that results from an applied stress. What is stress strain curve […]
What is the effect of high temperatures on material property?
What is the effect of high temperatures on material property? Stress-strain diagrams are obtained at specific temperatures. High temperature reduces material stiffness and strength, while low temperature increases material stiffness and strength. Almost all materials creep over time if exposed to elevated temperatures under applied load. How does increased temperature affect the performance of metals? […]

How do you identify a transfer function from a filter?
How do you identify a transfer function from a filter? You can look at the values of the transfer function as frequency approaches zero and infinity. A low-pass-filter transfer function will go to zero as frequency approaches infinity while a high-pass filter will not. What is the transfer function of a low-pass filter? This transfer […]
What is the daily driving limit?
Which of these should not be done with sharps?
Which of these should not be done with sharps? DON’T throw loose needles and other sharps into the trash. DON’T flush needles and other sharps down the toilet. DON’T put needles and other sharps in your recycling bin — they are not recyclable. DON’T try to remove, bend, break, or recap needles used by another […]
When inductors are connected in series in a circuit the total inductance is?
When inductors are connected in series in a circuit the total inductance is? When inductors are connected in series, the total inductance is the sum of the individual inductors’ inductances. To understand why this is so, consider the following: the definitive measure of inductance is the amount of voltage dropped across an inductor for a […]
What is a 13 watt LED bulb equivalent to?
What are the types of chips?
What are the types of chips? Types of Chips Brittle material , such as cast iron and bronze. large chip thickness. low cutting speed. small rack angle. How Chips are formed in metal cutting? Chips are formed due to tearing and shearing. In the process of chip formation by tear, the workpiece material adjacent to […]
