What does variable valve timing mean? In internal combustion engines, variable valve timing (VVT) is the process of altering the timing of a valve lift event, and is often used to improve performance, fuel economy or emissions. Two-stroke engines use a power valve system to get similar results to VVT. How does variable valve timing […]
What does a maglev train use to reduce friction?
What does a maglev train use to reduce friction? Maglev is short for Magnetic Levitation. Hence, the train is using magnetism to reduce friction. By having magnets on the track be opposed to magnets on the bottom of the train, the magnetic repulsion keeps the train levitating slightly above the tracks. What is magnetic levitation […]
What is DIC used for?
What is DIC used for? Digital Image Correlation (DIC) is a precise, non-contact, and non-interferometric optical method used for measuring the displacement/deformation of a structural element/material subjected to external loading. What is the main purpose of strain gauge? A strain gauge is a type of electrical sensor. It’s primary use is to measure force or […]
What is a show review?
What is a show review? In a review, draw upon a show’s performance and production, and illustrate the strengths and weaknesses of a show, as well as what audiences might enjoy most. Reviews evaluate the overall production and performance of a show and also compare the show to the cast and crew’s previous work. Why […]
What does plastic deformation mean?
What does plastic deformation mean? 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 difference between elastic design and plastic design? Explanation: The main difference between […]
Do pedestrians always have the right of way in California?
Do pedestrians always have the right of way in California? Pedestrians do not always have the right of way under California traffic laws. California Vehicle Code 21950 is the California statute regarding the right of way for pedestrians. This law states that drivers must yield the right of way only within: any marked crosswalk, or. […]
How do you find the breakaway point in a root locus?
How do you find the breakaway point in a root locus? Follow these steps to find break-away and break-in points. Write K in terms of s from the characteristic equation 1+G(s)H(s)=0. Differentiate K with respect to s and make it equal to zero. Substitute these values of s in the above equation. The values of […]
How can we improve Lean Six Sigma process?
How can we improve Lean Six Sigma process? Lean Six Sigma uses a 5-step method to improve processes and solve problems called DMAIC. Define Phase: Define the problem. Measure Phase: Quantify the problem. Analyze Phase: Identify the cause of the problem. Improve Phase: Solve the root cause and verify improvement. What are the Six Sigma […]
Where are power factor correction capacitors installed?
Where are power factor correction capacitors installed? Capacitors are connected directly to the terminals of inductive circuit. Individual compensation should be considered when the power of the motor is significant with respect to the declared power requirement (kVA) of the installation. How does adding a capacitor improve power factor? Power factor correction capacitors increase system […]
Which software is used for drafting?
Which software is used for drafting? AutoCAD professional design Which software are used in the basic engineering drawing? Auto CAD is still the most widely used engineering drawing software. Utilizing C++ code allows engineers and drafters to customize CAD objects, resulting in more accurate and flexible drawings. For Mac and Linux, QCAD is the popular […]
