For this project, our group was tasked with designing a personalized helmet that meets the basic standard requirements for motorcycle or car helmets. We were required to create sketches of ideas and designs we might have regarding our helmet, and then use Autodesk Fusion 360 to create the final design. We wanted our design to cover most of the face, especially the ears, but still leave a lot of room for the driver/rider to see so it doesn't cover their line of sight. Of course, we wanted to add a chin strap so the helmet doesn't fall off, but most importantly, we wanted to add extra padding so no one out there gets a gnarly concussion with a good ol' case of CTE when they're older.
Concepts
Acceleration- is a change in speed over a period of time; the higher the acceleration, the faster the change in speed. For example, if a car goes from 0 miles per hour (mph) to 60 mph in 2 seconds, it is a higher acceleration than if the car goes from 0 mph to 40 mph in 2 seconds. Acceleration is a rate of change of speed; NO change means NO acceleration. If something is moving at constant speed, it is NOT accelerating.
Coefficient of friction- is the measurement of the level of friction embodied in a particular material. The formula is μ = f/N, where μ is the coefficient of friction, f, is the amount of force that resists motion, and N is the normal force. Normal force is the force at which one surface is being pushed into another.
Crumple zones- are areas of an object designed to deform and crumple in an impact, as a means to absorb the energy of a collision. The fronts of most automobiles are designed as crumple zones to protect the passengers from frontal collisions.
Drag- is a term used in fluid dynamics that is sometimes referred to as air resistance or fluid resistance. Friction is one of multiple factors that influence the amount of drag encountered by a body moving through a fluid such as air or water.
Inertia- when an object remains still or moves in a constant direction at a constant speed.
G-Force- a force acting on a body as a result of acceleration or gravity, informally described in units of acceleration equal to one g.
Friction- is a force that resists motion when two objects or surfaces come in contact.
Force- causes masses to accelerate; they are influences that cause a change of movement, direction, or shape. When you press on an object, you are exerting a force on it. When a robot is accelerating, it does so because of the force its wheels exert on the floor. Force is measured in units such as pounds or newtons. For instance, the weight of an object is the force on the object due to gravity (accelerating the object towards the center of the earth).
Kinetic Friction- occurs when two objects are moving relative to each other and rub together (like a sled on the ground).

Reflection
I looked at this project and thought, "Hey, designing a helmet? Can't be that hard." But Mr. Tronconi played me like a fool for I had never been so wrong in my entire left. This project drove me crazy. Insane. It was a good introduction to Autodesk Fusion 360, don't get me wrong, but you have no idea how many sleepless nights I had thinking about how I was ever going to finish this thing. And when I did sleep, I had nightmares of being haunted by a talking helmet mocking me for never being able to finish creating it. I will never get that image out of my head. Anyway, 2 weeks past the due date and a fight with my mom later, my group and I finally finished making our personalized 3d helmet.
