Helmet part two 

Intro: 

For this we had to create a 3-d model of a helmet design and use some of the following concepts to assess the safety and usability of our helmet. 


Concepts: 

Mips: (Multi-directional Impact Protection System) 

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).

Helmet Research

Reflection:During this project I struggled greatly through multiple obstacles whether difficulty of fusion, 360, incorrect training videos and lack of time all made this a difficult project, however I persisted where I was strong in our capstone project and helped support my team members as much as I could.  Due to this, two things I did well at during this project was work as a Communicator and Collaborator, I worked well as a communicator due to our team needing some tight leadership often when group maters would get distracted, this is where I felt I excelled at bringing back the group and getting us to keep thinking about the project and remain focused. Secondly I did well as a collaborator as I knew we had a rather short period of time for this project and we would require all the team we could get, due to this I made sure to come to class everyday with the goal of achieving some task no matter how small to keep the project moving forward. 

Two things I did not do well were work as a Critical thinker and Conscientious Learner, I didn't work well as a critical thinker during this project as I failed to be able to grasp all parts of this project and relied on team mates for understanding the more critical components and leading the project in innovating. Secondly I lacked in being a conscientious learner as I struggled to comprehend the more difficult 3d modeling and rather than trying to struggle and achieve learning in such short time I stayed to my strengths and tried to focus more on my team. I have a lot to learn from this project from time management to learning to trust my team mates and work together.
