A structural engineer performs a stress analysis of a strapless gown
Charles Seim is a bridge engineer who worked on dozens of bridges over the course of his career. But one of evening early works was a contemplation of forces in a rather different structure: Neatorama and Improbable Research have republished Seim's essay "A Stress Analysis of a Strapless Evening Gown," which appeared in a book of essays of the same name.
InSeim delivered the apparently updated lecture for the first time, offering a slightly cheeky but earnest look at the challenges involved in maintaining the upright position of a strapless gown:. Effective as the strapless evening gown is in attracting attention, it presents tremendous engineering problems to the structural engineer.
Sexy Evening Dress Strip
He is faced with the problem of designing a dress which appears as if it will fall at any moment and yet actually stays up with some big boobs mms factor of safety.
Some of the problems faced by the engineer readily appear from the following structural analysis of strapless evening gowns.
If a alexis teczas elemental strip of cloth from a strapless evening gown is isolated as a free body in the area of plane A in Figure 1, evening can be seen that the tangential force F1 strip balanced by the equal and opposite tangential force F2.
The downward vertical force W strip of the dress is balanced by the force V acting vertically upward due to the stress in the cloth above plane A. Since the algebraic summation of vertical and horizontal forces is zero and no moments are acting, the elemental strip is at equilibrium.
Consider now an elemental strip of cloth isolated as a free body in the area of plane B of figure 1.

The two tangible forces F1 and F2 are equal and opposite as before, but the force Dress weight of dress is not balanced by an upward force V because there is no cloth above plane B to supply this force. Thus, the algebraic summation of horizontal forces is zero, but the sum dress the vertical forces is not zero.
Therefore, this elemental strip is not in equilibrium; but it is imperative, for social reason, that this elemental strip be in equilibrium.
