What is profile tolerance? In GD, profile tolerance defines a uniform boundary around a surface within which the elements of the surface must lie. Profile is a complex tolerance that simultaneously controls a feature’s form, size, orientation, and sometimes location. The top figure shows the profile tolerance applied to a curved surface. How many types […]
What is the maximum shear stress?
How do you find the voltage across a capacitor?
What effects do grazing animals have on the growth of grasses?
What effects do grazing animals have on the growth of grasses? In the field, grasses may respond three different ways to grazing overall: decreased growth, equal growth, or increased growth. When growth is decreased by grazing, grazing will cause the plant to have slowed growth or will cause the plant to stop growing all together. […]
What is meant by shear stress?
What is meant by shear stress? Shear stress, force tending to cause deformation of a material by slippage along a plane or planes parallel to the imposed stress. The resultant shear is of great importance in nature, being intimately related to the downslope movement of earth materials and to earthquakes. What is shear stress and […]
What happens when to the spectrum of a signal when it is sampled?
What happens when to the spectrum of a signal when it is sampled? One of the basic DSP principles states that a sampled time signal has a periodic spectrum with period equal to the sample rate. The derivation of can be found in textbooks [1,2]. You can also demonstrate this principle numerically using the Discrete […]
What were the criteria and constraints of the problem facing the engineers?
What were the criteria and constraints of the problem facing the engineers? Explain the terms “criteria” and “constraints.” Criteria are things the design needs to do in order to be successful–its requirements. Constraints are limitations on the design. These may be materials available, the cost of the materials, the amount of time they have to […]
Will warmer weather stop the coronavirus?
Will warmer weather stop the coronavirus? Warmer temperatures may make this virus less effective, but less effective transmission does not mean that there is no transmission. We still need to take strong precautions. Furthermore, researchers noted that it can take years for new viruses to settle into a predictable pattern. Should a child wear a […]
What are the advantages and disadvantages of fission?
What are the advantages and disadvantages of fission? Advantages and disadvantages of nuclear power stations Advantages Disadvantages Produces no polluting gases. Waste is radioactive and safe disposal is very difficult and expensive. Does not contribute to global warming. Local thermal pollution from wastewater affects marine life. What are the advantages of using fission as an […]
What technology is used in aerospace engineering?
What technology is used in aerospace engineering? As a result, aerospace engineers use computational fluid dynamics (CFD) and chemistry solvers to develop the next generation of aircraft engines. ANSYS’ Combustion portfolio helps aerospace engineers design engines. Ansys’ Combustion portfolio is well suited to these multiphysics simulations. What are six different forms of technology that aerospace […]
