Have you ever needed to do a certain simple task, but wished there was a machine to do it for you? The purpose of a Rube Goldberg machine is to create a complicated system in order to complete a tiny, simple task. What is a Rube Goldberg machine you may ask? A Rube Goldberg machine is an over- engineered contraption that uses a chain reaction to accomplish simple tasks such as turning on the music, pouring a glass of water, etc. This specific Rube Goldberg machine’s task is to move the last…

The teardrop design makes it much easier to balance these forces. the only forces exerted upon the riders are the force of gravity and the normal force The force of gravity is at all times directed downwards and the normal force is at all times directed perpendicular to the seat of the car. Since the orientation of the car on the track is continuously changing, the normal force is continuously changing its direction. Feelings of weightlessness and heaviness are associated with the normal…

Differential Services When a car makes a left turn, the left side wheels naturally turn slower than the outside wheels on the right because the exterior wheels have to travel farther than the inside wheels make the turn. For this reason, tires have to be able to move independently and at different speeds to avoid slipping. This gives the car more power and control in the turn. A differential is a mechanical set of simple gears that allow the wheels to rotate at independent speeds, and to be…

During the 17th century, an English scientist Sir Isaac Newton showed the scientific research for rocketry. Newton represented his idea of motion into three different laws. These explained how rockets work and why they work in space or any other sort of mediums. The first movement law is an object in motion will stay in motion unless acted upon by another force. The second law states, acceleration of an object is exerted by a net force is directly proportional to the magnitude of the net force.…

For my orthographic drawing, I created three different views of my putt putt boat. I created a top, front and side view of my boat. I created an orthographic drawing because it accurately shows the top, front and side views clearly and more precisely. I was representing a 3d object in 2 dimensions. My three views show how each side of the boat looks in detail and the accurate measurements of the boat. To create the hull, we shaped a piece of aluminum into a “pocket” by using sandpaper to sand…

1. Measure the distance from the top of the third floor balcony to the first floor using a tape measurer. It should start from the top railing of the balcony to until it touches the floor. 2. Take a meter stick and place the front of the car at zero. Turn on the car and let it run until the front reaches the end of the meter stick. Make sure to use a timer to see how long it takes the car too travel that far. Divide the change in distance it travel by the time it took to find the velocity of…

Mouse Killing Car Project While building and testing a mousetrap car the builder must understand a few simple but, vital mechanics. The vehicle will be propelled by the pulling force of a small mousetrap. The end goal of building this car is to have it go from one end of the room to the other on top of carpet. Leverage, kinetic energy, and friction; are things to take into consideration while testing and building the car. There are two types of levers to keep in mind. The first is the lever arm…

Swipe bloodstains which is in the catorgory of transfer bloodstain patterns, are created when a wet bloody object comes in contact with a target surface. Its use to identify an object or body part. A wipe pattene is created from an obkect moving through the a bloodstain, while a swipe pattens is created from an obect leaving bloosstain. Number is mark a swipe bloosstain becasue there seems to be a swipe of a hand print or sometime of object that has moved through the bloodstain, their are also…

Paragraph 1: A lever is a simple machine, which is a long rigid object resting on a pivot or a fulcrum, which rotates. This reduces the effort that is needed to move something. In this experiment the lever is the catapults arm. The lever we have used for the throwing arm is classified as a third class lever. The base of the catapult is the fulcrum, where it pivots off. The load is the beanbag on the end of the arm and the effort is how much it takes to pull down the arm of the catapult. Tennis…

There is a common saying that states, “Which weighs more; 200 pounds of bricks or 200 pounds of feathers?” One might say that they both weigh the same; however, the answer is the feathers because you also have to carry the weight of the great injustice done to those poor birds. When I was asked to list all the things I carry, I started listing the physical items, but after a while, I realized that there emotional items that I carry as well. I carry memories and feelings that either haunt or…
