2. Siding (construction) - Wikipedia

   en.wikipedia.org/wiki/Siding_(construction)

   Other types of sheet metal and steel siding on the market at the time presented problems with warping, creating openings through which water could enter, introducing rust. Hoess remedied this problem through the use of a locking joint, which was formed by small flap at the top of each panel that joined with a U-shaped flange on the lower edge ...

3. Sheet metal forming simulation - Wikipedia

   en.wikipedia.org/wiki/Sheet_metal_forming_simulation

   Today the metal forming industry is making increasing use of simulation to evaluate the performing of dies, processes and blanks prior to building try-out tooling. Finite element analysis (FEA) is the most common method of simulating sheet metal forming operations to determine whether a proposed design will produce parts free of defects such as fracture or wrinkling.

4. Slope deflection method - Wikipedia

   en.wikipedia.org/wiki/Slope_deflection_method

   The slope deflection method is a structural analysis method for beams and frames introduced in 1914 by George A. Maney. [1] The slope deflection method was widely used for more than a decade until the moment distribution method was developed. In the book, "The Theory and Practice of Modern Framed Structures", written by J.B Johnson, C.W. Bryan ...

5. Tape correction (surveying) - Wikipedia

   en.wikipedia.org/wiki/Tape_correction_(surveying)

   When distances are measured along the slope, the equivalent horizontal distance may be determined by applying a slope correction. The vertical slope angle of the length measured must be measured. (Refer to the figure on the other side) Thus, For gentle slopes, < % =

6. Corrugated galvanised iron - Wikipedia

   en.wikipedia.org/wiki/Corrugated_galvanised_iron

   Corrugated galvanised iron (CGI) or steel, colloquially corrugated iron (near universal), wriggly tin (taken from UK military slang), pailing (in Caribbean English), corrugated sheet metal (in North America), zinc (in Cyprus and Nigeria) or custom orb / corro sheet (Australia), is a building material composed of sheets of hot-dip galvanised ...

7. Incremental sheet forming - Wikipedia

   en.wikipedia.org/wiki/Incremental_sheet_forming

   However, studies have shown that it can be applied to polymer and composite sheets too. Generally, the sheet is formed by a round tipped tool, typically 5 to 20mm in diameter. The tool, which can be attached to a CNC machine, a robot arm or similar, indents into the sheet by about 1 mm and follows a contour for the desired part. It then indents ...

8. Grade (slope) - Wikipedia

   en.wikipedia.org/wiki/Grade_(slope)

   Slope may still be expressed when the horizontal run is not known: the rise can be divided by the hypotenuse (the slope length). This is not the usual way to specify slope; this nonstandard expression follows the sine function rather than the tangent function, so it calls a 45 degree slope a 71 percent grade instead of a 100 percent. But in ...

9. Structural shape rolling - Wikipedia

   en.wikipedia.org/wiki/Structural_shape_rolling

   Structural shapes can be rolled in different ways such as the “easy-way”, the “hard-way”, heel in/out, ball in/out, leg in/out, stem in/out, and off axis. The hard-way would be bending the workpiece in the orientation where its moment of inertia is the greatest. The easy-way is bending the workpiece along the axis with the smallest ...
