The pressure on a horse's back can affect their performance during the equestrian competition. A better pressure distribution on the surface of the horse's back can be obtained using a custom saddle, considering the rider's weight and back anatomy. The first part of the paper presents a recent study regarding the mathematical and CAD methods used to generate the hyperbolic paraboloid of the saddle surface. The second part of the paper shows the saddle design modelled using CAD software. The horse's back and rider's anatomy stay at the base of the saddle's surface. The saddle surface is divided into several areas for a better and more accurate evaluation. The third part of the paper presents the saddle evaluation using the finite elements method, using two load simulation cases in different rider situations. The improved shape of the saddle and conclusions are shown in the last part of the paper.

Additive manufacturing is a technology used in a wide range of industrial applications, from the digital model to the final physical production and often testing of parts. In this paper a radio-controlled airplane model was designed, analysed in terms of aerodynamic performance, and manufactured using the thermoplastic filament extrusion process. The preliminary aerodynamic analysis resulted in a maximum lift coefficient of about 1 corresponding to a drag coefficient of 0.058. This paper deals with the description of the additive manufacturing procedure of the radio-controlled model components and, finally, the assembly procedure of the whole model. At the end it can be stated that the thermoplastic extrusion process can be successfully used for the manufacture of radio-controlled model airplane or scale model airplane for the purpose of determining aerodynamic performance and conducting tests in wind tunnels or during flight.

The paper presents the design of a paraglider airfoil with superior flight characteristics, which provides safety, comfort and is easy to maintain by the user. The aerodynamics of paraglider airfoil are complex because they involve unstable turbulent three-dimensional airflows over flexible and deformable limits. The main improvement of the paper is the increase of the lift/drag ratio obtained by modifying the aerodynamic profile in the area of the leading edge, according to the "shark nose" model, and adding a reinforced structure in the flight edge to maintain the ideal shape of the aerodynamic profile at different angles of attack. The paper presents aerodynamic calculations, on a lifting surface of the paraglider airfoil that respects the NACA 2412 profile, made with a MathCAD program through which the coordinates of the profile were obtained at any point. The Paratailor 9 software was used to generate the paraglider model. The structural evaluation of the recreational paraglider model that meets the wishes of the current buyers is also presented.

The aerodynamic evaluation of vehicles body structure represents a significant stage in a car body design, having a considerable implication in fuel reduction and an increased vehicle stability on the road. The aim of this paper is to determine the aerodynamic coefficient, illustrating the airflow streamlines around the body of a VAN and reducing the aerodynamic coefficient by adding air deflectors to the vehicle body structure. The starting point of the CFD aerodynamic study is represented by the determination of the air flow regime around the vehicle body, followed by the determination of the aerodynamic coefficient and the lift coefficient for the base model of the vehicle. In the second stage the reduction of the aerodynamic coefficient is done by adding the air deflectors in the rear side of the vehicle. The aerodynamic study is performed for each vehicle model separately, resulting three simulation cases at a 25, 35 and 45 m/s velocity. The last part of the paper presents the conclusions of the obtained results and the strong and weakness points by using the CFD simulation in vehicles aerodynamics evaluation.

The Proposition 4 from the 11-th volume (called Book of Lemmas) of „Great Books of the Western World” (printed in USA in 1952) presents the properties of a remarkable curve from Antiquity. This curve was studied by Archimedes, who called it Arbelos and it looks like a shoemaker's knife. It consists of 3 semicircles. The first part of the paper is dedicated to the description of an original mechanism, conceived to plot the above-mentioned curve. It is made of a rotating driving element and two dyads of RRR type. The curve plotted by the mechanism checks the equality of areas described by Archimedes. He proved (by using geometric reasonings) that the area of a circle whose diameter is equal to the height of the right triangle inscribed in the Arbelos curve’s big semicircle is equal to the Arbelos curve’s area. In the second part of the paper, the authors modified the mechanism’s parameters and obtained 3 particular cases of Arbelos curves. These particular curves, plotted with the modified mechanism, are also composed of 3 semicircles whilst exhibiting other equalities between areas. The authors used geometric reasonings to prove the equality between the area of each particular curve and the area of a circle whose diameter is equal to the leg of a right triangle inscribed in the big semicircle of the studied particular curve.

This paper is about very interesting elements found in the daily life: signs, symbols and pictograms. From the sunrise till sunset, the people is surrounded by these things which may help to have an easier life. We have learned a lot about the capacity of these elements to act as a main guide, using many times just graphics. We have understood that signs, symbols and pictograms must catch the people`s attention. These ones have to guide, allow, warn or forbidden something, inform or assure the final destination for a traveler. We have identified the typology of these graphic representations and the working process to create pictograms. Some findings and results are explained in the paper.

The paper presents an interlocking system designed to fix and hold together the panels of a modular house. The house modules are flat square panels, almost identical, which need to be hold using a locking system. The locking system is a simple, but solid construction, capable to resist to repeated assembling and disassembling operations. It consists of some linkage mechanisms and a ratchet; it is hand-powered in order to ensure a fast mounting of the panels. In this paper are presented all the steps necessary to be followed and the restraints of the design process.

Pigments with special effects are nowadays utilized in the graphic engineering and design to achieve an added value of the final product. Daylight-invisible, UV-visible fluorescent pigments can be used as markings, sensors, as well as special design or security feature. Red and green UV-visible fluorescent pigments used in this experiment were mixed in the transparent base and screen-printed using the 60 l/cm mesh on the white uncoated paper, by applying different number of printed ink layers: one, two and three. Prints were then subjected to the accelerated ageing in a weathering chamber. Ink layer thickness and colorimetric properties of the unaged and aged prints were analyzed. Microscopic and macroscopic images of the prints were taken before and after the ageing process do assess the subjective visual difference between the unaged and aged samples. Results of this research have shown that one printed layer of the ink had inadequate visual response of fluorescence because of the effect of the optical brighteners in the paper. Higher number of the ink layers on print displayed better fluorescence effect and improved light fastness compared to the print obtained by applying only one ink layer. Results of the colorimetric measurements, as well as microscopic and macroscopic images, displayed the objective and subjective differences in the color appearance of the unaged and aged prints. Thereby, results of this research provided
