What is Flow Energy Do fluids at rest possess any flow energy explain? 4-58C Flow energy or flow work is the energy needed to push a fluid into or out of a control volume. Fluids at rest do not possess any flow energy. What is Earth’s energy flow? Energy flows are the energy transformations and […]

What are the three metaphors in Sonnet 73? Shakespeare expresses three major metaphors in this sonnet. The first is about age, the second about death, and of course, love follows. These three metaphors create an enjoyable poem. The first metahphor that Shakespeare uses is that of a tree in the fall. How many quatrains are […]

What is a strong argument? Definition: A strong argument is a non-deductive argument that succeeds in providing probable, but not conclusive, logical support for its conclusion. A weak argument is a non-deductive argument that fails to provide probable support for its conclusion. What is inductive argument examples? An example of inductive logic is, “The coin […]

How do you calculate the gear ratio of a bevel gear? Calculating the gear ratio of bevel gears When referring to bevel gears, we need to consider that it will be equivalent to the number of teeth of the driving gear divided by the number of teeth of the driven gear (RT= Z1 / Z2). […]

Which of the following is an example of transactional information? Which of the following is an example of transactional information? Withdrawing cash from an ATM, making an airline reservation, purchasing stock, trends, and sales projections. What encompasses all organizational information and its primary purpose is to support the performance of managerial analysis tasks? What is […]

What is the relation between convection heat transfer coefficient? The convective heat transfer coefficient, h, can be defined as: The rate of heat transfer between a solid surface and a fluid per unit surface area per unit temperature difference. The convective heat transfer coefficient is dependent upon the physical properties of the fluid and the […]

What is the role of the pancreas in controlling blood sugar levels? When blood sugar is too high, the pancreas secretes more insulin. When blood sugar levels drop, the pancreas releases glucagon to raise them. This balance helps provide sufficient energy to the cells while preventing the nerve damage that can result from consistently high […]

What is the effect of the degree of crystallinity on fatigue resistance of polymers? However, qualitatively speaking the greater the crystallinity the harder the polymer, or the greater the strength as compared to the totally amorphous structure of a given average molecular weight. This is so, as the crystallinity reduces the degree of freedom for […]

What is a class 1 lever? In a Class One Lever, the Fulcrum is located between the Load and the Force. The closer the Load is to the Fulcrum, the easier it is to lift (increased mechanical advantage). Examples include see-saws, crow bars, hammer claws, scissors, pliers, and boat oars. What is an example of […]

What is the difference between plane stress and principal stress? These planes are called the principal planes. It will also be noted from the figure that the normal stresses acting on the planes of zero shear stress are either a maximum or minimum. These normal stresses are called principal stresses. The principal stresses are labelled […]
