Background
This assignment introduced us to the theoretical and digital application of 3D modeling using the program of Autodesk 360. Tasked with creating a personalized helmet, we watched numerous video tutorials to fully understand all aspects of Autodesk 360 and begin creating our individual three-dimensional models. Our group decided to create a motorcycle helmet with built-in speakers with Bluetooth compatibility. We spent several weeks researching the market to learn what buyers want from a helmet, safety standards, materials, and calculations in order to test our design. Finally, we utilized Autodesk 360 to create our personalized helmets. I have attached our report below.

Key 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 (or dynamic friction) occurs when two objects are moving relative to each other and rub together (like a sled on the ground).

Reflection
Overall, this project was not only one of my least favorites, but one that I struggled with considerably. One of my greatest weaknesses was my patience. 3D modeling was a rather foreign concept to me, creating a daily sense of uncertainty and self-doubt. Rather than allowing myself to learn and become more comfortable with this type of design, I would become frustrated and sometimes even give up entirely. Another aspect of this project I had a difficult time with was my time management. Considering how daunting this assignment was, time was of the essence. Rather than treating it as such, I focused on the tasks that, in retrospect, weren't the most important. I ultimately ran out of time and was forced to hastily finish my Autodesk design, something I should have allocated much more time for.
However, this project did lead to personal growth. One of my strengths was asking for help when I needed it. I relied on the advice of other group members, information available online, and my teacher's guidance to learn, progress, and eventually complete the assignment. Another element I was successful with was my leadership. I urged my group members to keep working and finish the task at hand. While this personalized helmet was rather difficult for the most part, I did overcome obstacles and stay determined.
