What is the difference between linear and non linear vibration?
In general all systems are nonlinear but we simplify this nonlinear vibration to linear ones so that we can get approximate results. Approximate results are still good results in many cases. For example when you analyze the vibrations of the simple pendulum for small vibrations you don't need to include aerodynamic drag which is a nonlinear in its nature. By neglecting the nonlinear parts we can derive the second order differential equations which describes the motion of the system in this case gives linear vibration of simple pendulum. Another good example would be an examination of system which consists of block of mass m, spring with stiffness k and viscous damper with damping coefficient c and let's say that the block of mass m is in contact with the surface. Now the spring stiffness and the viscous damping are in reality nonlinear but for small vibration we assume they are linear. The bloc of mass m is in contact with the surface so that means that between the block and the surface is a friction. So if we analyze this system with nonlinear terms we would need to include the nonlinear stiffness, nonlinear damping coefficient and nonlinear friction. These would result in the time consuming calculation and in the end the results would little more precise than the approximation. In nonlinear analysis we attack the differential equation which describes the motion of nonlinear system with small parameter and with this we expand the solution. This method is called perturbation method. To solve nonlinear systems you need to use specific perturbation method and these methods are: Straightforward expansion, domain perturbation, multiple scale analysis etc. For more information check my site Linear Vibration.

What quality of diamond is used for cutting glass?
Diamonds used in glass-cutting tools are industrial quality diamonds, which sell for much less than gem-quality stones. From the US Geological Survey Web site: "Natural industrial diamond normally has a more limited range of values. Its price varies from about $0.30 per carat for bort-size material to about $7 to $10 per carat for most stones, with some larger stones selling for up to $200 per carat."

Cost breakup of conducting a survey?
Cost of conducting a Survey depends upon : 1) Are you designing you survey of your own OR hiring a professional for that. 2) Is your Survey hosted on a free Survey Site ? 3) What are your priorities with Survey respondents ? 4) Which Survey Company or website you are using to conduct Survey? Recommendations: 1) This depends all upon You and your survey topic; If you think you can make a good questionaire, only then you should try that otherwise hire some company professionals to do that for you because a badly designed survey will not benefit your business. 2) Use a website that doesn't cost you for hosting a Survey. 3) Survey sites like Global Survey Market offer you to choose RANK of your Survey respondents. RANK is the reputation of a User on website. Higher rank means heigher cost. Choose your rank wisely. For Ex: If you are conducting a survey about beverages, You can choose least RANK users. If You are conducting a Survey about some high level topic or you think a ordinary user will not be able to answer these questions or your survey contains some sensitive data, then you should choose high rank users accordingly. 4) Choose a Survey company very carefully. You should check their website and contact their customer support by email and evaluate the company.
Why is it necessary to secure aerial maps before conducting reconnaissance survey?
Securing aerial maps before conducting a reconnaissance survey is essential to ensure accurate planning and navigation during the survey. It allows surveyors to identify key landmarks, potential obstacles, and specific areas of interest beforehand. Using up-to-date and precise aerial maps helps to improve the efficiency and effectiveness of the survey by providing clear guidance and reducing the risk of errors or misinterpretations.
What is physical survey?
A physical survey involves conducting on-site inspections and measurements of a property or location to assess its physical attributes. This can include documenting features such as buildings, infrastructure, topography, and boundaries. Physical surveys are essential for various purposes, including land development, construction projects, and property assessment.
What is a professional survey site?
