  2. Borden Base Line - Wikipedia

    en.wikipedia.org/wiki/Borden_Base_Line

    Borden Base Line American Society of Civil Engineers plaque at the Tilton Library in South Deerfield. The Borden Base Line is a historic survey line (7.42 miles, 39,009.73 feet (11,890.17 m) long) running north–south through Hatfield and South Deerfield, Massachusetts. It was completed in 1831.

  3. Cooling load temperature difference calculation method

    en.wikipedia.org/wiki/Cooling_load_temperature...

    The respective tables of data were generally developed by using the more complex transfer function method to determine the various cooling loads for different types of heating. [ 2 ] [ 3 ] The results gained by doing so are then normalized for each type of heat gain used for the tables, CLTD, CLF, and SCL.

  4. Blazed grating - Wikipedia

    en.wikipedia.org/wiki/Blazed_grating

    A special form of a blazed grating is the echelle grating. It is characterized by particularly large blaze angle (>45°). Therefore, the light hits the short legs of the triangular grating lines instead of the long legs. Echelle gratings are mostly manufactured with larger line spacing but are optimized for higher diffraction orders.

  5. Eurocode 1: Actions on structures - Wikipedia

    en.wikipedia.org/wiki/Eurocode_1:_Actions_on...

    In the Eurocode series of European standards (EN) related to construction, Eurocode 1: Actions on structures (abbreviated EN 1991 or, informally, EC 1) describes how to design load-bearing structures. It includes characteristic values for various types of loads and densities for all materials which are likely to be used in construction.

  6. Macaulay's method - Wikipedia

    en.wikipedia.org/wiki/Macaulay's_method

    Simply supported beam with a single eccentric concentrated load. An illustration of the Macaulay method considers a simply supported beam with a single eccentric concentrated load as shown in the adjacent figure. The first step is to find . The reactions at the supports A and C are determined from the balance of forces and moments as

  7. William Whiting Borden - Wikipedia

    en.wikipedia.org/wiki/William_Whiting_Borden

    William Whiting Borden was born into a prominent and wealthy Illinois family, the third child of William and Mary DeGarmo Whiting Borden. Borden's father had made a fortune in Colorado silver mining, but the family was unrelated to the Borden Condensed Milk Company—an advantage for Borden since if asked about his wealth, he could honestly reply that his family was often mistaken for "the ...

    en.wikipedia.org/wiki/Shop_drawing

    Leite et al. [3] compared types of clashes identified in a manual coordination process (overlay of 2D drawings on a light table by pairs of subcontractors) and through automatic clash detection using a Building Information Model (BIM). The automatic clash detection identified several clashes that were missed by the subcontractors, who were ...

  9. Newmark's influence chart - Wikipedia

    en.wikipedia.org/wiki/Newmark's_influence_chart

    In 1883, he solved the problem of stresses produced at any point in a homogeneous, elastic, isotropic soil medium as the result of a point load applied on the surface of an infinitely large half-space. [1] Nathan Mortimore Newmark (1910-1981) attended Rutgers University. He graduated in 1930 with High Honors and Special Honors in civil engineering.
