How do you find the maximum unambiguous range? The maximum range from which a transmitted radar, lidar, or sodar pulse can be reflected and received before the next pulse is transmitted. This range, rmax, is given by rmax = cT/2, where T is the interpulse period and c is the speed of light (or speed […]
Is strength a material property?
Is strength a material property? Design terms. Ultimate strength is an attribute related to a material, rather than just a specific specimen made of the material, and as such it is quoted as the force per unit of cross section area (N/m2). The ultimate strength is the maximum stress that a material can withstand before […]
What is Matrix chain multiplication method in dynamic programming?
What is Matrix chain multiplication method in dynamic programming? A dynamic programming algorithm Take the sequence of matrices and separate it into two subsequences. Find the minimum cost of multiplying out each subsequence. Add these costs together, and add in the cost of multiplying the two result matrices. What is the best way to solve […]
What is an isolated system example?
What is an isolated system example? A thermos flask is the best example of an isolated system. A thermos flask is used to keep things either cold or hot. Thus a thermos does not allow energy for transfer. An isolated system does not exchange energy or matter with its surroundings. What is meant by an […]

Which brick manufacturing process produces a molded brick? extrusion process What supports the overhanging bricks in the accompanying image? What supports the overhanging bricks in the accompanying image? A hidden lintel (like a steel angle). What is Rowlock brick? Rowlock. A brick laid on its face, or edge. Soldier. A brick laid on its end […]
What is the rms value of full wave rectifier?
What is the rms value of full wave rectifier? Full-wave Rectifier Average Value Then we can see that a full-wave rectifier circuit converts BOTH the positive or negative halves of an AC waveform into a pulsed DC output that has a value of 0.637*AMAX or 0.9*ARMS as shown. How do you calculate the average voltage […]
Why do ionic compounds conduct electricity in aqueous solution and not in solid state?
Why do ionic compounds conduct electricity in aqueous solution and not in solid state? Ionic compounds conduct electricity when molten (liquid) or in aqueous solution (dissolved in water), because their ions are free to move from place to place. Ionic compounds cannot conduct electricity when solid, as their ions are held in fixed positions and […]
How do you read a screw thread callout?
How do you read a screw thread callout? Here are the five steps to interpreting thread callout: Look at the numbers in the callout. Understand the first number in the callout – This indicates the major diameter. Understand the second number in the callout – This indicates the distance between threads. Read the length – […]
What is refrigerator in thermodynamics?
What is refrigerator in thermodynamics? A refrigerator is a device which is designed to remove heat from a space that is at lower temperature than its surroundings. The same device can be used to heat a volume that is at higher temperature than the surroundings. In this case the device is called a Heat Pump. […]
