What is the role of planning engineer? Planning Engineers help engineering teams deliver projects on schedule. They develop strategies, determine material and labor costs, monitor crew performance, ensure health and safety regulations are obeyed, and that communications channels are open. Which task best fits the role of a design engineer? Explanation: Design engineers study, research […]
What is the formula for a random number generator?
What is the formula for a random number generator? This generator produces a series of pseudorandom numbers. Given an initial seed X0 and integer parameters a as the multiplier, b as the increment, and m as the modulus, the generator is defined by the linear relation: Xn ≡ (aXn-1 + b)mod m. Or using more […]
Why do cars need to be aerodynamic?
Why do cars need to be aerodynamic? The main concerns of automotive aerodynamics are reducing drag, reducing wind noise, and preventing undesired lift forces at high speeds. For some classes of racing vehicles, it may also be important to produce desirable downwards aerodynamic forces to improve traction and thus cornering abilities. What is the purpose […]
What is the overall effect of using a chronological text structure?
What is the overall effect of using a chronological text structure? Readers can follow the progress of events surrounding an important moment. Chronological order helps readers understand the order in which things happened, from the first event or detail to the last. This helps give an accurate picture to how the event unfolded and what […]
What is the importance of annealing?
What is the importance of annealing? Annealing is a heat treatment process which alters the microstructure of a material to change its mechanical or electrical properties. Typically, in steels, annealing is used to reduce hardness, increase ductility and help eliminate internal stresses. What is annealing and its types? The process of heating a metal or […]
What are the design requirements?
What are the design requirements? 2.5 Design Requirement. A thing that is needed or wanted. A thing that is compulsory; a necessary condition. Design requirements are the functional attributes that enable the team to convert ideas into design features. What are the requirements of a good product design? Top 10 Factors determining Product Design Customer […]
What is FCC crystal structure?
What is FCC crystal structure? Metallic Crystal Structures. FCC (face centered cubic): Atoms are arranged at the corners and center of each cube face of the cell. How many octahedral holes are there in the FCC? 4 octahedral holes What is the packing factor of FCC crystal structure? It can be proven mathematically that for […]
What is the difference between open die forging and closed die forging?
What is the difference between open die forging and closed die forging? While impression or closed die forging confines the metal in dies, open die forging is distinguished by the fact that the metal is never completely confined or restrained in the dies. Most open die forgings are produced on flat dies. What is open […]
How do I keep weeds from growing in my gravel?
How does plastic deformation occur?
How does plastic deformation occur? Plastic deformation is the permanent distortion that occurs when a material is subjected to tensile, compressive, bending, or torsion stresses that exceed its yield strength and cause it to elongate, compress, buckle, bend, or twist. What is the cause of deformation? Deformation is caused by stress, the scientific term for […]
