The crumple zone is an essential part of any car that provides safety for the passengers during collusion with another car or object. Without any form of a crumple zone, passengers would be much more likely to suffer from injury or possibly death. For this same reason, crumple zones have existed in cars for years and are still being improved to this day. One way you can better understand a crumple zone is by creating a scale model. My group and I have made multiple crumple zones with trial and error to better understand them and how they work. My group and I came into this lab with very little to no experience with crumple zones. Before building anything, we had to come up with a design for the crumple zone. Our first design involved popsicle
My project consisted of a simple set of materials: a 30cm by 20cm cardboard box, a toilet paper roll, industrial glue, 2 rubber bands, 4 water bottles, 2 Oreo cookie trays, packaging tape, and lead shielding sheets. The lead sheet was flattened, form-fitted and glued on the inner bottom of the cardboard box. This was done in order to provide the box a low center of gravity and to meet the minimum mass of 1 kg. Glued to the lead sheet was
Often after mixing an emulsion foam is produced. Foam is produced when pockets of air are trapped in a solid or liquid. Foams are a type of colloid. A colloid is a mixture between homogeneous and heterogeneous mixtures. Beaten egg whites and whipped cream are examples of trapped air in liquids. Marshmallows are an example of air trapped in solids.
sides on a cube and this gave rise to idea for a project. The final result
Planning Firstly here is a list of equipment I used. Boiling tubes Weighing scales Knife Paper towels 100% solution 0% solution (distilled water) measuring beakers potato chips Cork borer. We planned to start our experiment by doing some preliminary work. We planned to set up our experiment in the following way.
Origami, from the original Japanese words ‘ori’ meaning folded, and ‘kami’ meaning paper, is the art of paper folding. The practice originally began as an artform, but recently it has been realised that the mathematics behind origami has many practical applications. This is due to the advances made in computer science and computational geometry. Some terms that are common in origami must first be explained in order for the tactics described below to be properly understood1. A crease, otherwise known as a fold can be convex or concave, referred to as a mountain fold, or a valley fold respectively. All the creases used form a crease pattern. If two or more creases intersect a vertex is created. If there is a series of successive creases relatively close to each other the resulting form is called a pleat. A crimp involves a reverse fold of convex and concave folds. Crimps and pleats form accordion and corrugated patterns, which are then used in a variety of applications, and a series of different combinations result in different crease patterns, the most notable of which are described further on.
The experiment was built in order to test our abilities to efficiently and correctly execute a separation of mixtures through deep brainstorming and teamwork.
In Hutchison (2015), it is expressed that the concept of stress pileup is a complex model of double ABC-X. Every family has some type of devastating crisis, for me, it was an actual experience of my own that caused a lot of stress and concern for my family. Dealing with a bad marriage, I came to a breaking point in my life with allowing too much mental stress in my life that it resulted in attempting to take my life. The stress I had placed on my children and my parents, has continued to stay with them throughout the years, even though it has been over 16 years and I have made great positive advances in my life, their concerns seem to always be there.
During side impact crashes, cars can potentially flip. Side impact crashes are said to be the most dangerous type of car crash. The rear facing seat is the best option during this type of crash. If the car flips the sides of the seats are better equipped to harness the child in the seat. The seat is able to make pivoting motions because of the attachments to keep the child in a straight line. Keeping them in a straight line reduces the risk of injuries especially in the spinal cord.By having their back straight it won't bend or come close to snapping. A rear facing car seat protects the child by using a 5- point safety harness which is a system of hooks even used for race car drivers, and flight pilots.This allows the child to stay In the seat without them fal...
Crito is trying to persuade Socrates to escape not only because Crito feels he will lose a beloved friend, but also because he feels the majority will judge him for valuing himself over Socrates. In the passage, Socrates states many arguments to try and explain to Crito that the opinions of the majority do not and should not matter. The most compelling argument Socrates gives for this claim is when he states, “I am the kind of man who listens only to the argument that on reflection seems best to me” (Socrates, The Crito pg.4). I agree with Socrates’s claim not only because the words from the wise and the intelligent are far more likely to be sound, but also because listening to the knowledgeable is more likely to lead you to a more fulfilling
When it comes to cars, there are plenty of safety features incorporated by manufactures to ensure a smooth and safe ride. Some of these features seat belts, airbags, and antilock brakes. Nowadays, there have been great improvements to technology within cars to aid in the avoidance of collisions altogether. Examples of these technologies include blind spot detection, backup cameras, 360-degree cameras, and autonomous driving. Many of these newer safety features are there to avoid collisions. However, whenever a collision does occur, there is not much there to protect passengers in the rear of the car. Looking into this, there is evidence that shows that rear passengers do obtain injuries in collisions and pose the threat of contributing to others injuries. So, why are rear passenger airbags not standard in your vehicle?
Warping means that the shape of the brakes has already changed because of excessive heating and uneven cooling that's caused by pressing the brake pads onto the rotor of the vehicle for a long time. When the shape of the brakes is altered, they will no longer be able to provide even braking power. Aside from this, brake warping also causes damage to the car's rotor disk whenever the brakes are applied. This eventually leads to uneven wear and tear, which is known as a major cause of a lot of vehicular accidents. Warping is commonly addressed through
We separated into groups of two each, making sure that we had the following materials for the lab: graduated cylinder, plastic sandwich bag, starch solution, twist tie, 500-mL beaker, iodine solution, and a pair of goggles and an apron (for the person handling the iodine solution).
The Sand Cone Model describes business improvement as a process which should be based on improving specific competitive dimensions in a different order (Meredith & Shafer, 2013). For instance, a business which is struggling with quality outputs should place an emphasis on improving the quality of its outputs first. Businesses that produce high quality outputs are successful over the long term. Matthew 7:24-25 (ESV) states, “Everyone then who hears these words of mine and does them will be like a wise man who built his house on the rock. And the rain fell, and the floods came, and the winds blew and beat on that house, but it did not fall, because it had been founded on the rock.” When a business builds its foundation on
There is a lot more to know about bubbles. Hopefully your amazing demonstration will get your students interested in learning more about the science of bubbles!
Crumple zones- are a structural feature used in automobiles. They help by absorbing the impact; this is by spreading the impact through parts of the car instead of in the one spot. This reflects back onto law number one, two and three. This is shown when the car hits the object it causes the car to slow down or completely stop (1). The crumble zone would protect the driver because all the energy has been diverted around the car, instead of the one spot. As a result of the cars mass and its acceleration, the force can be calculated (2). When the car crashes it’s most likely that the object w...
