What are some of the common barriers to dislocation movement that can be used to strengthen metals? Stress can produce a barrier to dislocation motion. Impurity generates local shear at A and B that opposes dislocation motion to the right. Impurity generates local shear at C and D that opposes dislocation motion to the right. […]
Which is the whole number?
Which is the whole number? In mathematics, whole numbers are the basic counting numbers 0, 1, 2, 3, 4, 5, 6, … and so on. 17, 99, 267, 8107 and are examples of whole numbers. Whole numbers include natural numbers that begin from 1 onwards. Whole numbers include positive integers along with 0. Is 0 […]
What are the types of topology?
What are the types of topology? There are five types of topology in computer networks: Mesh Topology. Star Topology. Bus Topology. Ring Topology. Hybrid Topology. What is mixed topology? Hybrid topology is an integration of two or more different topologies to form a resultant topology which has many advantages (as well as disadvantages) of all […]
Which of the following is a eutectic substance?
Which of the following is a eutectic substance? Examples of Eutectic Systems Sodium chloride and water form a eutectoid when the mixture is 23.3% salt by mass with a eutectic point at -21.2 degrees Celsius. The system is used to make ice cream and to melt ice and snow. The eutectic point of the mixture […]
How fast does the NASA crawler move?
Which of the two materials brittle vs ductile usually obtains the highest ultimate strength and why?
Which of the two materials brittle vs ductile usually obtains the highest ultimate strength and why? Answer: Explanation: Ductile materials typically have a higher ultimate strength because they stretch absorbing more energy before breaking. Why does a brittle material have a higher Young’s modulus than a ductile material? Because the area under the stress-strain curve […]
How do you find the molar mass of a gas?
Does porosity affect density?
Does porosity affect density? Looked at from the porosity perspective, bulk density increases as pore space decreases. The relationship of bulk density and porosity is reciprocal. As one increases, the other decreases. Generally speaking, loose, rich in organic matter, well aggregated and porous soils have a low bulk density. What is porosity composites? Porosity is […]
Why is counter flow heat exchanger better in terms of heat transfer?
Why is counter flow heat exchanger better in terms of heat transfer? Counter flow heat exchangers are inherently more efficient than parallel flow heat exchangers because they create a more uniform temperature difference between the fluids, over the entire length of the fluid path. For example, one fluid may make 2 passes, the other 4 […]
Do double pane windows reduce heat?
Do double pane windows reduce heat? Improve efficiency and save money: Double pane windows insulate better than single pane versions, making your home more efficient. A home that retains heat in winter and keeps heat out in summer is more affordable to heat and cool. In this way, double pane windows deliver savings to help […]
