This is where the string will be attached to the drive wheels. If the cable tie is slipping, then apply a small dot of glue onto it. Large Wheels – using really large diameter drive wheels gives even larger mechanical advantage for greater distance. Wheel – mousetrap car rolls on wheels this is the geometric shape of a circle.
Step 3: Install the Drive Wheels
You use this principle in your mousetrap car, only in reverse. Rober goes and meets one of his friends and mentors Al, who is a high school physics teacher in Texas. Inspired by the form of a car, KPF’s design creates a new “body” around the existing “chassis” of the museum. The rooftop is converted into a party space that can be rented out. Sitting atop the existing structural system like the body of a car mounted to its frame, the steel “ribbons” evoke a sense of speed and movement and are brushed to avoid creation of glare. The design offers a contemporary interpretation of the mid-century, space-age “Googie” architectural style that characterizes Los Angeles.
Follow these design principles to create a winning mousetrap powered car design.

But it's only in California where there are U.S., Japanese, European and Korean design studios all within 120 miles of each other. With more than 15 design studios in one area it probably beats any place else in the world in sheer numbers. Northern Italy is probably the only region that comes close. Turn a brief description of each design and include answers to the following design considerations listed above. Turn in any hand drawings of the designs that help demonstrate the designs.
Introduction: 3D Printed Mouse-trap Cars
This will help in traction, as just CDs will be very slippery. We left it for a day to get over our frustration before tackling the project again from scratch on Tuesday night. Flynn’s teacher had suggested using larger wheels; we’d initially tried using juice and milk bottle caps because they wanted the projects to use as many recycled items as possible. I headed to the store and splurged on blank CD’s and we started again. The faster the car is accelerating the larger the force but the larger the mass the larger the resistance will be to the acceleration. Think of how a large truck or a train is slower accelerating than an automobile.
Hot glue craft sticks together to form a rectangle that's 4 sticks long (picture 1). Place a piece of duct tape over the hole in the center of the DVD. Turn the DVD over and place the faucet washer into the center of the DVD onto the tape. Phiaro can do design, engineering, modeling including interior and exterior, UIUX, everything in our company. We also have 6 locations and over 300 employees in total in Japan.

Valentine’s Day is a great opportunity to inspire your student’s LOVE for science! Engage your kids with science concepts such as diffusion, density, and surfactants. These three, hands-on science projects include the Dancing Conversational Hearts, Rainbow Heart, and...
The first car I built I used a framework of bamboo which required additional bracing as the tension of the mousetrap pulling on the string across the length of the chassis was causing it to twist. The next generation of mousetrap cars was built from balsa wood and the current generation use a chassis made from a foam block. It is my plan to expand on this and introduce even greater educational aspects that go along with the projects. This will be primarily in the area of physics and math applications.
Additionally, mousetraps are simpler to use than other potential mechanisms such as wind-up motors or rubber bands. Now it’s time to watch your brand new mousetrap car and show off your creation! You can race against another one of your friends’ cars or test out how fast it will go on a long track by itself. Just make sure that you don’t let anyone touch it while it’s running, or they may get hurt.
As the size of the drive wheel increase the torque required to start a wheel turning also increase. At some point a drive wheel can be so large that there is not enough force from the mouse trap to keep the wheel turning. This axle-to-wheel ratio is part of a mousetrap vehicle's gearing that needs to be understood in order to build the perfect racer for the contest at hand. For long distance racers a large diameter drive wheel with a small diameter drive axle is desired. For speed trap racers a smaller diameter drive wheel with a larger diameter drive axle is desired. Inertia is the resistance that an object has to a change in its state of motion, the more inertia that an object has the more force that will be required to change is state of motion.
But, if the lever arm is to short the pulling force will be so larger that the drive wheels will spin out at the start. The goal with any speed trap racer is to use as short a lever arm as possible or just before the point where the drive wheels spin out. The maximum acceleration of a mousetrap vehicle will depend on the amount of grip or traction the racer's wheels have on the floor. In order to walk forward your foot needs to be able to push against the floor and the floor has to push back. It is the friction or traction between the bottom of your feet and the floor that provides the grip you need to move. It is also the friction that exists between the road and a wheel that keeps the wheel from spinning out thereby moving the car along the road.
It makes a great 4-H or class project that provides an opportunity to learn some basic physics and engineering skills. If you are using this as a unit for students you may set up an area to begin trials. Students can use a stopwatch and a tape measure to calculate speed. Distance may also be recorded and used to determine the winning car. Allow students to experiment with their car after a couple of trials.
Overall this is a really fun and exciting day for the students to see how their designs performed compared to the other teams. First we will begin by cutting our axles from either metal rod or dowel. We will be cutting the axle to 3 and 3/4". We will need two axles. I have had the best luck with positioning the wheels in a vertical way, as well as putting the body of the car in a perpendicular position relative to the bed. When everything has been tested, you can add some detail to your car if you want to.
But as the size of the drive wheel increase so does the amount of torque is required to start and keep the wheel turning. At some point a drive wheel can be so large that there is not enough force from the mouse trap to start and/or keep the wheel turning. Different lengths of lever arms can be used to increase and/or decrease the pulling force and change the amount of string that can be pulled off the drive axle. Changing and/or attaching a lever arm to the mousetrap is the number one way to control a mousetrap vehicle's performance. Larger drive wheels have a greater travel distance per each turn compared to smaller drive wheel.
Loop the string onto the cable tie from the underside of the dowel (picture 1). Phiaro has been in business for more than 80 years and has always put quality first, with experienced craftsmen and women who always strive for perfection. We also believe in developing new technologies and are working on new technologies such as EV cars, EV batteries, and UIUX. Chrysler Pacifica, the No.3 automaker's advanced studio in carlsbad, CA, still operates in this way.
