Making a 3D helmet
In this lab, Olivia, Ben, Rodrigo and I made a 3D helmet tom fulfill the needs of a basic standard motorcycle/bicycle helmet.
Here is a link of the 3D helmet we did. Sorry Mr. Tronconi, we made a joke and made the password "tronc sucks". Don't deduct points from us, we didn't mean for it to be rude. The button below will bring you to our helmet

designing the helmet
When designing the helmet, I was really intrigued by how this software works. it was really cool how you can make a helmet with Auto-desk fusion 360. Designing the helmet was pretty tedious at times but after getting the hang of it we had a great outcome and it looks awesome. The helmet is purple with a design of a dragon on the head and the mouth guard of the helmet. The helmet has a hard outer shell so there will be little to no head injuries using this helmet. It also has a mouth guard to protect your mouth and face if you go down. This project was very fun. I loved learning about the different aspect to what a good helmet needs and I also found out definitions to vocabulary words I didn't know. My group mates were very hard working and they were very great to work with and we never got off task. Here are some sketches below that inspired our helmet design
KEy concepts
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).
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.
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.
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.
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.
INERTIA: when an object remains still or moves in a constant direction at a constant speed.
