What is a HEC RAS model? HEC-RAS is a one-dimensional steady flow hydraulic model designed to aid hydraulic engineers in channel flow analysis and floodplain determination. The results of the model can be applied in floodplain management and flood insurance studies. How do you add ineffective areas in HEC RAS? The user can use the […]
How can you control the space ahead of your vehicle?
How can you control the space ahead of your vehicle? To drive defensively, you must manage the road space around your car. You can do that by controlling your speed, properly positioning your car in a lane and communicating with other road users. The crucial concept is keep a safe distance from the car in […]
What are some of the advantages of foamed polymers and parts?
What are some of the advantages of foamed polymers and parts? Other advantages of foamed plastics over nonfoamed polymers include improved thermal insulation, relatively high strength per unit weight, ease of foam formation, ease of molding, and lower dielectric constant (Figure 14.2). What is plastic foam? Foamed plastic, synthetic resin converted into a spongelike mass […]

How do you make a Chebyshev filter?
How do you make a Chebyshev filter? Designing the Filter You must select four parameters to design a Chebyshev filter: (1) a high-pass or low-pass response, (2) the cutoff frequency, (3) the percent ripple in the passband, and (4) the number of poles. What are Chebyshev filters used for? Chebyshev filters are used for distinct […]
What is combined loading?
What is combined loading? Combined loading occurs when a set of different types of loads are applied, for example, bending moments, axial forces, torsion, and transverse forces (See Figure 8-20) Remember: Normal stresses add algebraically! What is the principle of superposition answers? The superposition principle states that when two or more waves overlap in space, […]

How are single crystal turbine blades made?
How are single crystal turbine blades made? A common method is the Bridgman method to grow single crystals. In this method a casting furnace is used for crystal growth. In this process, a mould must first be made of the blade. Molten wax is injected into a metallic mould of the desired turbine blade and […]
