How do you find the K value of a root locus? Sketch the root locus. To find K for 20% overshoot, we have to identify the location of poles that generates 20% overshoot. Then using the values of the poles and 1 + KG(s) = 0, we can compute the gain K at the poles. […]

What is the theme of the poem No man is an island? The phrase ‘no man is an island’ expresses the idea that human beings do badly when isolated from others and need to be part of a community in order to thrive. John Donne, who wrote the work that the phrase comes from, was […]

What is it called when a substance changes from a vapor to a liquid? Condensation. Gas. CONDENSATION When steam is cooled, it releases thermal energy and turns into its liquid state. This process is called condensation. What is the process of turning from liquid into vapor? Evaporation happens when a liquid substance becomes a gas. […]

What is the peak to peak voltage of 120 VAC RMS 60hz? The 120V is the RMS voltage. And the peak voltage for this is actually 170V. So the peak of this voltage is actually a whole lot bigger than 120V. And if you look at it from peak-to-peak, then the voltage from an AC […]

Who has responsibility for health and safety in the workplace? Business owners and employers are legally responsible for health and safety management. This means they need to make sure that employees, and anyone who visits their premises, are protected from anything that may cause harm, and control any risks to injury or health that could […]

How do you calculate volume of water flowing through a pipe? The volume of a portion of the fluid in a pipe can be written as V = A d V=Ad V=AdV, equals, A, d, where A is the cross sectional area of the fluid and d is the width of that portion of fluid, […]

What is the pitch spacing between the weld segments? The pitch is the distance between centers of each weld segment (not the empty space between the segments; see Figure 2). When intermittent welds are placed on both sides of a joint, they can be directly opposite each other (chain) or they can be offset (staggered). […]

Why is it important to review literature in research? The purpose of a literature review is to: Identify need for additional research (justifying your research) Identify the relationship of works in context of its contribution to the topic and to other works. Place your own research within the context of existing literature making a case […]

What are alpha and beta phases? In titanium processing: Alpha and beta phases. The atoms of pure titanium align in the solid state in either a hexagonal close-packed crystalline structure, called the alpha (α) phase, or a body-centred cubic structure, called the beta (β) phase. What is a primary phase? By definition, a primary phase […]

What is a spent solvent? A spent solvent is a type of spent material, which is defined by the EPA as “any material that has been used and as a result of contamination can no longer serve the purpose for which it was produced without processing.” Under the federal Resource Conservation and Recovery Act (RCRA), […]
