Device Purpose  Destructo boots destroys any kind of fruit. It is activated by putting a fan on, which in turn creates enough force for a floatable device to float accross an aquarium which pops a balloon that holds the arm of the Destucto boot in place. When the balloon is popped the arm swings freely, and comes in contact with the desired fruit and in turn destroys it for no apparent reason.

Turn on the fan  Activating the fan provides a force to accelerate the pointy boat across the aquarium

Popping the Balloon  When the pointy boat reaches the other side of the aquarium, the needle on the end of the boat collides with the balloon, resulting in much popping.

Releasing the String  The balloon was holding the rope that held the Destructo Boot Arm in a near vertical position, and popping it frees the rope, unfettering the Destructo Boot Arm

Destructo Smash!  Freeing the Destructo Boot Arm allows it to swing down from its near-vertical position, bring the full force of the swinging Destructo Boots into on the unsuspecting fruit

Energy Conversions  Rotation of the fan blades is used to move air, which moves the boat. The boat’s motion is conveyed to the balloon through the needle, releasing the string, and allowing the conversion of the Destructo Boots’ gravitational potential energy into kinetic energy, which is transferred to the stationary fruit

Results

Calculations  Fan Force  Tension in the String –Assuming the rope is horizontal before the collision –T=Wcos(angle) –T=Wcos(89.5)=22lb(cos(89.5))=.192lb  GPE to KE –Mgh=.5mv^2-masses cancel out –32.2(5ft)=.5(v^2) –V=17.9ft/s, disregarding friction and air resistance Mv b =mv b ’+mv destroyed ’

Conclusion  Through a series of Energy conversions beginning with switching on a fan, the most efficient and economically feasible fruit crusher has been created
