Research This project is about what makes bouncy balls bouncy. My hypothesis is that the borax is what makes it bouncy and It will take more borax than glue to make the ball bouncier. This is important to know this because if you add too much or too less you will not have a real bouncy ball . There are three main thing we have to remember while doing this project. I will be mentioning three thing in my S.A.:Materials, Momentum, and Velocity. To make the bouncy ball bouncy it will need the…

Vertical dimension (VD) defined in the Glossary of Prosthodontic Terms as "The distance between two selected anatomic or marked points”. Occlusal vertical dimension (OVD) defined as "The distance between two selected anatomic points when in maximal inter-cuspal position”.(1) The OVD is determined by the repetitive contracted length of the elevator muscles which sets the jaw-to-jaw relationship.(2) During growth and development OVD affected by three factors: Growth of the ramus, gonial angle of…

While designing any aerodynamic body an unspoken assumption of bilateral or mirror symmetry is taken into consideration. Argument against this bilateral symmetry states that “once the velocity of sound is exceeded, the laws of aerodynamics change in such a way as to make it seem inadvisable to arrange the components of an airplane side by side or abreast in a supersonic stream unless there are compelling reasons for such an arrangement.“ 2.1.1 Wave Drag This type of drag is formed as a result…

ABSTRACT Flakiness & Elongation index is one of the most prominent criteria that govern behavior and performance of aggregate in the bituminous mixes. The strength and serviceability requirements of bituminous mixture such as Stability, Flow, Voids in Total mix (VTM), Voids Filled with Bitumen and (VFB) highly depend on the physical properties of aggregates. This study conducted by observing the effect of flakiness & elongated index by adding different percentages from 0% to 50% of flaky &…

Problem: how does the angle of trajectory effect the horizontal distance of a bottle rocket Background research: When an object is in the air and has no forces acting on it other than gravity it becomes a projectile. (Henderson, 1996) Gravity causes the projectile to accelerate toward the ground in a uniform arc like a rainbow does. this shape is known by scientists and mathematicians as a parabola, and objects that fly in the shape of a parabola are said to be in parabolic motion. A projectiles…

Everybody has heard of paper maché, but not everyone knows of the much more useful alternative, paper maché clay. It’s simple to use, and easy to fill a space. It is much better than normal paper maché clay, even if it has it’s flaws. The benefits far outweigh the flaws, making it an extremely useful tool in making masks. Masks can be made from all kinds of material, but using paper maché clay is the easiest way to have the most artistic freedom. Paper maché clay can be messy, but so can paper…

Introduction When a cough isn’t just a cough and may in fact be fatal. Whooping cough is that cough, the one that you should hope never to encounter. The Wichita Eagle states that there were three cases diagnosed in Kingman, county, Kansas. I wondered why this would make the news. Three cases do not sound like much to worry about, however, by the end of the article I realized this is indeed something that should be taken seriously and was indeed newspaper worthy. The article introduces us to…

central nervous system (Mitropoulos, Hermsen, Rotschafer, 2012). It is rapid progressing and can lead to death or debilitating effects if not diagnosed and treated quickly. In order to diagnose a patient with bacterial meningitis a cerebral spinal fluid (CSF) examination is necessary. To obtain the CSF from a patient a lumbar puncture is usually done. When the physician is performing the lumbar puncture they can also determine the pressure in the subarachnoid space using a sterile manometer…

Members from BHP Billiton LTD, have approached filtration consulting, to design a cyclone separator system for a process involved in the production of zinc oxide particles. The clients has also asked for advice on the use of bag filters as a standalone system, or in conjunction with a cyclone separator system. The filtration system must have a collection efficiency of 95% of the zinc oxide particle from a gas flow at 1000°C and with a flow rate of 3820 (Nm^3)/hr. One of the most common particle…
