{"product_id":"2940016244556","title":"EMPIRICAL FORMULAS","description":"This is intended to assist engineers to find formulas to fit their observations, so as to facilitate engineering calculations and to get exact interpolations. \u003cbr\u003e\u003cbr\u003eThe first five chapters deal with simple tests to be applied to a set of data to determine if they can be represented by certain simple types of equations; another chapter deals with the method of least squares; another with formulas for interpolation; another with approximate formulas for areas, volumes, moments of inertia, etc. The idea throughout is to help the engineer to simple working formulas representing his data, rather than any exact development of formulas representing natural laws. Every experimental and practicing engineer may find help in such a discussion. The treatment is sufficiently elementary to be within the capabilities of anyone who can use calculus.\u003cbr\u003e\u003cbr\u003eAlthough it is of the highest mathematical elaboration, it is quite easily comprehended by anyone who has had the usual college engineering training in the subject.\u003cbr\u003e\u003cbr\u003eThe most complete treatise on the subject ever published and the first book worthy of the title...\u003cbr\u003e\u003cbr\u003eA practical book and should be particularly valuable to engineers engaged in research, design, time study, estimating costs, testing and any other work involving the use of tabular values derived from experimental or other observed data.\u003cbr\u003e\u003cbr\u003eShould be found of value by those desiring to make up empirical formulas in given cases.","brand":"OGB","offers":[{"title":"Default Title","offer_id":47121349640432,"sku":"2940016244556","price":1.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/2940016244556_p0.jpg?v=1763631314","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/2940016244556","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
