Is Fourier series in time domain? The time domain signal used in the Fourier series is periodic and continuous. The Fourier series synthesis equation creates a continuous periodic signal with a fundamental frequency, f, by adding scaled cosine and sine waves with frequencies: f, 2f, 3f, 4f, etc. What do Fourier series coefficients represent? In […]
How do mechanical properties of polymers change with temperature?
How do mechanical properties of polymers change with temperature? The effects of temperature on the mechanical properties of polymers change considerably, especially within the heat distortion temperature range. The heat distortion takes place over a wide temperature range that, for many resins used in civil engineering, lies between 20 and 80 ºC11. What factors affect […]
How do you make a rapid sand filter?
Which of the following is a dimensionless parameter?
Which of the following is a dimensionless parameter? The correct answer is option (3) Kinematic viscosity. A dimensionless quantity means the quantity that can be represented by M°L°T°. Which dimensionless number classifies the flow into different compressible regimes? The Reynolds number is commonly used to characterize if a flow in a pipe is laminar or […]
What body system supports the body with structure?
What body system supports the body with structure? The skeletal system works as a support structure for your body. It gives the body its shape, allows movement, makes blood cells, provides protection for organs and stores minerals. The skeletal system is also called the musculoskeletal system. What is the structure of the body system? An […]
How does the engine convert energy stored in fuel?
How does the engine convert energy stored in fuel? The chemical energy of a fuel can be converted by combustion into thermal, or heat, energy in a heat engine. The engine in turn converts the thermal energy into mechanical energy, as in engines that drive shafts. How do engines transfer combustion into useable energy? In […]
What season is represented in the Southern Hemisphere?
What season is represented in the Southern Hemisphere? winter At which position is the Southern Hemisphere experiencing spring? position B. What season will it be in the southern hemisphere in 6 months? Our northern winter is in Dec, Jan and Feb, whereas the southern winter is in June, July, and August. Each of our summers […]
How does crystallinity affect polymer properties?
How does crystallinity affect polymer properties? Crystallinity: The crystallinity of the polymer increases strength, because in the crystalline phase, the intermolecular bonding is more significant. Hence, the polymer deformation can result in the higher strength leading to oriented chains. How does molecular weight affect crystallinity? Narrow molecular weight, linear polymer chains, and high molecular weight […]
What is the coefficient of friction between the crate and the floor?
What is the coefficient of friction between the crate and the floor? Static and Kinetic Friction The coefficient of static friction between the crate and floor is 0.700 and the coefficient of kinetic friction is 0.600. Is rubber a grippy? Rubber is grippy due to the massive amount of friction that occurs between objects. What […]
How do you know if a liquid is Newtonian?
How do you know if a liquid is Newtonian? A classic Newtonian fluid is water. Water has a very predictable viscosity and will always flow predictably regardless of the forces acting on it. Newtonian fluids also have predictable viscosity changes in response to temperature and pressure changes. What is Newtonian and non-Newtonian fluids? Newtonian liquids […]
