An analysis of the relationship between locomotive speed and wind direction was carried out on the amount of drag force faced by the CC203 locomotive, one of the fastest locomotives used in Indonesia today. Based on the results of the analysis, an alterna... see more

Free fall motion in air medium is only influenced by gravitation acceleration. However, there are several variables that caused the observations to be different with the concept. Variables, such as air drag and terminal velocity, are often teachers not pr... see more

A new attempt to use Polyvinylpyrrolidone (PVP) as a bio-drag reducing polymer agent for human blood flow has been studied. PVP was added at 0, 500, 750 and 1000 part per million (ppm) and mixed with human blood at room temperature for 2 minutes. Then, a ... see more

Circular cylinder has a strong  adverse pressure gradient. When a fluid flows around the circular cylinder, it will produce aerodynamics force. One of them is  the drag force which strong enough. Hence, control of flow need to reduce the drag fo... see more

Case-reports of broken modular femoral necks have implied increased shear loading as the main culprit. The study aim was to determine whether total hip endoprostheses with modular femoral necks produced larger magnitudes of shear force, smaller leg length... see more

In external ballistics of a conventional spin-stabilised artillery projectile, there are a numberof trajectory models developed for computing trajectory elements having varying degrees ofcomplexity. The present study attempts to propose a single mathemati... see more

The turbulent flow friction of a water solution with a small amount of surfactant additive is dramatically reduced when compared to that of pure water. This effect offers a significant reduction in pumping power and energy consumption. Commercial implemen... see more

Here is studied a classic problem of the motion of a projectile thrown at an angle to the horizon. The air drag force is taken into account as the quadratic resistance law. An analytic approach is used for the investigation. Equations of the projectile mo... see more
