For this project, our goal was to design a helmet using Auto-desk Fusion 360. The helmet must support the highest degree of safety, as well as be comfortable and aesthetic for the user.

Learning objectives:

• Create a 3D model of a helmet using Auto-desk Fusion 360

• Define relationships between the elements of the helmet and build the assembly

• Generate photo-realistic images of the helmet

• Describe how helmets provide impact protection by dissipating crash energy

• Explain Newton 2nd Law of Motion

• Calculate impact force

• Explain how friction and mass effect motion

• Describe the general structure and material used to create a helmet

Every TEAM must:

1. Create paper sketches of the personalized helmet (Orthogonal, and perspective.)

2. Create paper designs to decorate the Helmet (Use your team's logo, Be creative.)

3. Create a detailed 3D helmet (must be physically possible, surfaces must have a thickness, all elements must be included and properly modeled including hinges, glass, rivets and padding.)

4. A written design explanation of how your helmet meets the safety standards, materials, and possible extra functionalities. MUST INCLUDE THE KEY SCIENTIFIC CONCEPTS

5. A written report of your research (with cited sources.)

7. All written products (research report, design explanation, paper sketches, and 3d models) must be uploaded to your Digital portfolio.

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

Our Helmet

Reflection

This was personally my least favorite project we have done so far. I like designing on paper and in person but not online. It is super tedious and there are no current instructions to explain how to use such advanced software. Something I believe I did well was make the most of a situation with no resources. We took what we were given and tried our best using the little resources given to us. Its unfortunate we could not spend weeks on this project, which would have allowed us to create a better project. But we used our time the best we could and created a helmet using the little knowledge we had using online software. Something I wish I did better was time management and communication. It was a big project for a short period of time and maybe if our group split up the work better, we could have had a better final result. I also wish my group worked more equally, because when one team member is not doing their fair share of work, it slows us all down.
