When you increase the size of the wheel, the amount of torque necessary to begin a rotation increases as well. Ensure minimal friction on your moving parts. The faster a car can accelerate, the more momentum it can build up. A mousetrap car built for distance will have larger wheels travels a longer distance per turn , a longer lever arm increase the distance the car is able to travel , a smaller axle delivers more torque to the drive wheels and may be larger, due to the larger size of the wheels. And what worked best when attaching the bolts onto the axels, glue or electrical tape? Third Law — For every action there is an equal and opposite reaction. After the eye screws have been aligned, insert the rods into the hooks. Short lever arms increase the pulling force and the power output by decrease the pulling distance but increasing the speed.

Cut down on the number of pulleys and gears. Easily release the captured pest or any animals caught unintentionally. This is where you will glue your mousetrap. This will ensure that each of the wheel sizes will receive the same amount of energy. Ideally, you want your car to be shaped aerodynamically — that is, so that it presents the smallest possible surface area in the direction it will travel. The length of the string connecting the lever on the trap to the axel will remain constant through out the duration of the experiment.

There is no precise formula for how long the lever should be. Or, you can build your own. A complicated system of gears and pulleys can be useful when building a racer for distance, because they increase the overall torque. Step 3: Assemble the body Glue the side board to the deck to using some strong wood glue to ensure that the mouse car project does not come apart while in motion. However, large wheels also require more force to initiate motion. Inertia is the resistance that an object has to a change in motion. A single front wheel was used throughout the experiment Tests were ran to determine how far the car would travel and how fast they traveled a distance of five and feet.

If you want to create some classic look on your mousetrap car, you can use small wheels for the front sides and the large wheels for the rear sides. Position the trap as far forward as possible. The longer it is, the longer it will take for the car to accelerate, but the greater the distance will be. Now that you have drawn and drafted the wheels, use the utility knife to cut them out if you want to add more traction to your wheels, add the rubber bands around them. Thicken the Axle First, thicken the axle. On the other hand, if either end of a nail sticks out of your frame, it can have a minor effect. I'm doing this for an 8th grade science project and the model looked innovative and creative to me.

Your car can lose a lot of energy at the point where the axle touches the frame. A smaller wheel is easier to turn. Take two eye screws and insert them at the corners of the rear end of the mousetrap. This usually means having a long lever arm and a large axle-to-wheel ratio. Besides imparting knowledge, building a mousetrap car is also fun. . The only way to perfect your model is to experiment with small variations in design to determine what works best.

Doing this increases the structural strength of the car while minimizing the change to its air resistance and weight. Drill holes with a drill machine in the center of the circles. In redesigning this mousetrap car webpage I wanted to introduce more of the educational physics aspect to mousetrap cars. For example, find a thinner frame and wheels. The diameter of axle in relation to the diameter of the driving wheels is the mechanical advantage.

The car is then wound in the reverse direction with the help of its hind wheels, much like a pull-back car. A good standard is approximately 3 inches in diameter. The more rotational inertia the wheels have, the more force will be required the change the state of rotation. Align the eye screws properly so that you can slide the rods through them. If there were no friction it would continue to move in the same direction but the friction is an unbalanced force can you think of sources friction in the mousetrap car? Two layers of foam board would probably be used to cause the wheels to be more level and stable. In this Article: You can purchase kits online that provide you with all the parts necessary to put together a mousetrap racer.

However, first let us understand the working of this car. Most of the time, for mousetrap car assignments, all students will be required to use the same size of mousetrap so that everyone's car designs have the same amount of power. As a result, it will go slower, but move further. Computer simulation for Mousetrap car motion A mousetrap car is a small whose only source of motive power is a. This the can be very suitable if you are looking for distance-based competition. Reducing the mass also reduces the friction at the axle supports.
