What is constant head permeability test? The constant head permeability test is a laboratory experiment conducted to determine the permeability of soil. The soils that are suitable for this tests are sand and gravels. Soils with silt content cannot be tested with this method. The test can be employed to test granular soils either reconstituted […]
What is IEEE floating-point representation?
What is IEEE floating-point representation? The IEEE-754 standard describes floating-point formats, a way to represent real numbers in hardware. In single-precision and double-precision formats, there’s an assumed leading 1 in the fractional part. The fractional part is called the significand (sometimes known as the mantissa). What is the representation for IEEE single precision floating-point number? […]
What is meant by SHM?
What is meant by SHM? Simple harmonic motion is defined as a periodic motion of a point along a straight line, such that its acceleration is always towards a fixed point in that line and is proportional to its distance from that point. What is oscillatory motion give examples? Oscillatory motion is defined as the […]
What is tie line in phase diagram?
What is tie line in phase diagram? page 2 of 9. An isothermal (constant temperature) line through the alloy’s position on the phase diagram when it is in a two phase field, intersecting the two adjacent solubility curves, is called a tie line (yes, that’s the horizontal yellow line on the diagram). What is tie […]
Why ceramic matrix is not very commonly used in composites?
Why ceramic matrix is not very commonly used in composites? A strong bond would require a very high elongation capability of the fiber bridging the crack and would result in a brittle fracture, as with conventional ceramics. The production of CMC material with high crack resistance requires a step to weaken this bond between the […]
Which is example for Third Order lever?
Which is example for Third Order lever? In a third class lever, the effort is between the load and the fulcrum. Some examples of third class levers include fishing rods, cricket bats and chopsticks. Third class levers are different from first and second class levers because instead of force multipliers, they are speed multipliers. What […]
What does the evaporator do in a refrigeration system?
What does the evaporator do in a refrigeration system? The evaporator works the opposite of the condenser, here refrigerant liquid is converted to gas, absorbing heat from the air in the compartment. When the liquid refrigerant reaches the evaporator its pressure has been reduced, dissipating its heat content and making it much cooler than the […]
Can you add wind turbine to solar system?
What can bad brakes cause?
What can bad brakes cause? When the brake system becomes impaired, it can lead to irreversible damage to the tires. Slamming on the brakes due to worn pads, rotors, and calipers, leads to unbalanced tires. This, in turn, affects the tires, causing them to wear down much faster than they should. What are the signs […]
What is the relationship between voltage and current in a transformer?
What is the relationship between voltage and current in a transformer? is the relationship between the output and input currents of a transformer. So if voltage increases, current decreases. Conversely, if voltage decreases, current increases. What happens to the current when the voltage increases? The current is directly proportional to the voltage and inversely proportional […]
