Es increíble lo mucho que puede aprenderse de una simple viga! En pocos minutos vamos a vincular importantes conceptos de Resistencia de Materiales (RM) con los de la Teoría de la Elasticidad Lineal (TEL) experimentando con herramientas y tecnologías CADD+CAE.

Una reflexión sobre habilidades verbales y visuales para sacar provecho de los "grados de libertad (GDL)" presentes en los enunciados de los problemas de ingeniería. A tal efecto se aprovechan algunos resultados del desafío planteado como excusa para abordar estas ideas: https://grabcad.com/groups/weekly-challenge-group/discussions/a-mechanism-to-move-the-green-orange-rectangle

Cap screws and machine screws

dea
in Drafting
69 12 Intermediate
Cap screws and machine screws are similar in shape, differing only in their relative sizes. Machine screws are usually smaller in size, compared to cap screws. These are used for fastening two parts, one with clearance hole and the other with tapped hole. The clearance of the unthreaded hole need not be shown on the drawing as its presence is obvious. Figure 5.24 shows different types of cap and machine screws, with proportions marked Cap screws are produced in finish form and are used on machines where accuracy and appearance are important. As cap screws are inferior to studs, they are used only on machines requiring few adjustments and are not suitable where frequent removal is necessary. These are produced in different diameters, upto a maximum of 100 mm and lengths 250 mm. Machine screws are produced with a naturally bright finish and are not heat treated. They are particularly adopted for screwing into thin materials and the smaller ones are threaded throughout the length. They are used in fire-arms, jigs, fixture and dies. They are produced in different diameters upto a maximum of 20 mm and lengths upto 50 mm.

Conceptual Design of Dovetail Joint

Marcelo Valderrey

68 4 Beginner
Some solutions to the challenge posed by https://grabcad.com/steen.winther are presented: impossible dovetail joint? Each one starts their attempt from a particular situation, which can lead them to first find a solution (such as the rectilinear one) and later others (such as the circular ones). What this tutorial intends is to show the style of conceptual thinking that allows "discovering the rules behind particular cases" to conclude that all possible solutions actually derive from "the same idea". Note: this type of challenge is useful for those who do not know the solution or other similar cases. The idea is to force the process of generating and evaluating ideas. Once you know the case, the opportunity to discover solutions is lost!

Simple animations, frame by frame

Marcelo Valderrey
in Theory
67 0 Beginner
There are many efficient ways to make animations from CAD models, such as those created in the SolidWorks Motion module. However, simple animations, created frame by frame, are still very useful because of their flexibility to be edited with graphics and text, manipulate their timing and transitions, etc. This tutorial provides some tips for creating animated giffs in PHOTOSCAPE from images taken from the SolidWorks screen.

Analogies are always imprecise, but let’s risk one that equates a car with a numerical simulator, with their respective internal machinery “under the hood.”
