The Mechanics Behind a Mousetrap Car

p The Mechanics behind a Mousetrap Car

Mousetrap car is a very good illustration of conversion of energy . The energy for moving the car comes from the mouse trap . It is stored as spring potential energy . This is finally converted to kinetic energy of the moving car . Building the mouse trap car is about converting the potential energy to kinetic energy and transferring the energy . Finally all the energy is converted to dissipation energy due to friction

Many principles are involved in building this simple looking mousetrap car . Applying these principles helped [banner_entry_middle]

in making mousetrap car more efficient . The mousetrap car is designed keeping in view of these principles to move it faster and a longer distance . Some changes in the design increased both speed and distance . In some cases the change intended to increase speed also decreased distance and vice versa . There were some factors which contradicted each other as mentioned above . The experience in building the mouse trap car yielded many interesting results We used few instruments and materials . They are a wooden mouse trap CDs , two steel rods of 6mm diameter , aluminum strip , driller , drill bits , epoxy glue , few scrap wood pieces

Making mousetrap car is not very tough . We got a wooden mouse trap which is supposed to provide the energy . The spring has two arms . One of them is an arm which has to be fixed to the frame the other one is the one that is pushed and which moves . Fixing one of the arms to the frame is a little problem . We placed an aluminum strip and screwed it on to the frame making one of the arm fixed . The other end is left free

The wheels have to be fitted to the wooden frame . Two steel rods of about 6mm in diameter are taken . We used 4 compact disks (CDs ) as wheels . Attaching the wheels (CDs ) to the steel rod was a problem initially . We wooden pieces to cover the hole in the CD using epoxy . We drilled a hole of 6mm in the wood such that it is the centre of the CD . The rod is inserted into the hole drilled in the wooden portion of the CD . Epoxy is used to keep the wheel and rod intact . The wheels (which are paired using the steel rods ) are to front and rear ends of the wooden mouse trap by making grooves . These rods have to be fitted properly to the wooden frame work . The rods should be able to rotate freely

A string is to the free arm of the spring in the mouse trap The other end is wound around the axle (6mm steel rod ) of the rear wheels . The free arm is pushed making it store energy as potential energy in the spring . When the spring unwinds , it rotates the axle around which the string is wound . This makes the wheel rotate which moves the mousetrap car move forward . We have few problems in this process . The… [banner_entry_footer]
