• Shear Pin/Screw Calculations

    Crosssectional Area. The crosssectional area of a round shear pin is simple to compute. area = PI () * (diameter/2)^2. The computation for a screw is more complied. Because of the screw's threads, the diameter of the screw that should be used is less obvious. The narrowest crosssection of a screw, between the threads, is called the screw ...

    a) If the two sides measure x inches each and the sheet metal was 30 inches wide to begin with, then the crosssectional area can be expressed by the function: b) If you were to graph this function you would see a parabola that opens downward. The xvalue at the maximum point (called the vertex) can be found by: where a = 2 and b = 30.

  • Volume with cross sections: semicircle (video) | Khan Academy

    Let's take pi over eight out. Our volume is going to be equal to pi over eight times the definite integral from zero to one of xsquared minus two x plus one d x, which is equal to pi over eight. The antiderivative of this is x to the third over three minus xsquared plus x. We're going to evaluate that at zero and one.

  • Calculating Estimated Strip Widths

    The process of calculating a strip (blank) width essentially involves estimating the arc length (neutral line) of the bends and adding the sum of these bends to the lengths of all flat surfaces associated with the finished crosssection. In roll forming, a bend is formed progressively until the final forming angle has been achieved.
