## Develop the Equations for a Stress Field Around a Compound Elliptical Hole in an Uni-Directional Stress Field

Fixed-Price - Entry Level (\$) - Est. Budget: \$65 - Posted
I'm looking for an engineer to develop a set of piecewise equations for computing the stress field around a shaped hole in an infinite plate. The hole shall take the form of compound ellipses, which intersect at a points of equal slope (see attachment). The analyst will assume that the stress field of each of the compound ellipses will behave independently from one another. Verification of equal stress state at the intersection of the ellipses is required. The assumption will be further validated with finite element modeling in future work. The stress field around the perimeter of the ellipse will be a function of theta and will include the following parameters: R = Ratio of A-to-B (0<R<inf) M = curvature at intersection, squareness (-inf<M<0) The stress field around an elliptical feature can be found from a reference such as Peterson's Stress Concentration Factors, or other locations on the internet (e.g. http://www2.mae.ufl.edu/haftka/adv-elast/lectures/Sections14.1-2.pdf). The developed equations will be used to optimize the length-to-width ratio and squareness of such a hole in a known biaxial stress field, using stress superposition in a fatigue-critical application. Applicants should provide proposal with: 1. Estimated cost 2. Estimated number of hours to perform work 3. Soonest possible start date and associated finishing date >>>DELIVERABLE<<< The deliverable will be a PDF document with the derivation of a piecewise equation for the stress field around the perimeter of a shaped hole, as described in the attachment.

## Is there an algorithmic solution to this geometry problem?

Because the highway has a wider right of way than the country road, the corner of the field is closer to the country road than it is to the highway. In the attached paper, Geometry-Do:  Geometry without Multiplication, I present a heuristic method on pages 63-64.

## Add text to objects, C++/Qt

Fixed-Price - Expert (\$\$\$) - Est. Budget: \$1,500 - Posted
This program generates graphics shapes using input parameters. The graphics shapes need to display text data. The user needs to be able to enter the text data. The user needs to be able to select a font family and font size for text data. The user needs to be able to position the text data. The text variables are: designerName groupName shapeName parameterFileName date The font size can be different for each text variable Success looks like: A. Code meets style guidelines, is merged, and compiled B. In the compiled application a. the user can enter text data, font family, and font size b. the text is displayed on the graphic shape using font family & size c. the user can position the text on the graphic shape d. the exported printable file displays the text data in the correct font and size e. the text, font, size, and position information is saved in the file f. the text is displayed as before when the user switches to another part of the program and returns g. the text is displayed as before when the file is saved, closed and reopened Additional work is available.

## Tattoo Design

Fixed-Price - Intermediate (\$\$) - Est. Budget: \$50 - Posted
I started a tattoo design on my entire back and I need some illustration ideas to complete my vision. Im inspired by Sacred Geometry and want to incorporate this style on my tattoo. ... I need someone who can use the image om my back with my current tattoo and is able to incorporate sacred geometry in my tattoo. The geometry can go on top of the tattoo. Ideally, the geometry blends in with the Face tattoo and the other designs on my back.

## Looking for artists with talent for drawing and design to complete adult themed coloring book.

Fixed-Price - Expert (\$\$\$) - Est. Budget: \$250 - Posted
I need artists talented enough to help me complete an adult themed coloring book to be sold on my website. These coloring books will be limited edition, of very high quality, and are aimed at a niche audience. I will need to see samples of artist's work to see if they're the right fit. I aim to pay a \$250 advance if beginning criteria are met and will pay 1/4 royalty for each unit sold off of work.
