1) MAKE A HUMAN POWERED MECHANICAL DEVICE TO PICK THE STONES OF VARIOUS SHAPES, SIZE AND WEIGHT WHICH IS ON SOLID GROUND AND LIFT THE STONES UPTO CERTAIN HEIGHT (15CM) WITHOUT USING ANY ENERGY STORING DEVICES AND ELECTRONIC GADGETS.
NOTE: - WEIGHT OF THE STONES WILL BE 250 GMS, 500GMS, 750 GMS.
2) IRRIGATION IN HILLY SLOPES HAS ALWAYS BEEN TEDIOUS. AVAILABILITY AND REACH OF WATER SOURCE ACT AS BOTTLENECK FOR DEVELOPMENT OF CIVILIZATION IN THOSE AREAS. HEAVY COST REQUIREMENT FOR PUMPING WATER, LACK OF SKILLED MANPOWER AND LIMITED ACCESS TO THE FUEL OR ELECTRIC DRIVE HAVE LONG BEEN TROUBLING LIFE OVER THERE. WE THOUGHT OF HELPING THEM OUT. “DESIGN A MECHANISM WHICH LIFTS WATER TO A HEIGHT OF MORE THAN 0.5 METERS”. ELECTRIC MOTORS OR ANY OTHER FUEL OPERATED ENGINES SHOULD NOT BE A PART OF YOUR MECHANISM.
3) RECURRING CONTRAPTION:
DESIGN A CONTRAPTION, WHICH CONTAINS CERTAIN SET OF STEPS WHICH ARE TO BE REPEATED 3 TIMES.
FORMAT:
STARTING POINT
STEP 1 TO STEP N (RECURSION 1)
STEP 1 TO STEP N (RECURSION 2)
STEP 1 TO STEP N (RECURSION 3)
STEP 1 TO END AT ANY STEP….
RULES:
1. MIN 4 STEPS SHOULD BE THERE IN 1 RECURSION.(NO LIMIT FOR MAX.)
2. ONLY WHEN ALL STEPS ARE FINISHED ONCE, SECOND RECURSION SHOULD START.
3. EACH RECURSION SHOULD FOLLOW THE SAME STEPS OF PREVIOUS ONE.
4) MAKE A CONTRAPTION WITH AS MANY ENERGY CONVERSIONS AS POSSIBLE WITHIN 3 MINUTES. THE CONTRAPTION DURING ITS PROGRESS SHOULD PERFORM TWO TASKS
TASK (1) DEMOLITION OF A STRUCTURE (MADE UP OF 6 STACKED BRICK) WITH MORE THAN ONE BLOW.HERE, REMOVAL OF ATLEAST 2 BRICKS WOULD BE CONSIDERED AS COMPLETION OF TASK.
TASKS (2) PASS THE TENNIS BALL THROUGH THE FRAME, CARRYING OUT PARABOLIC MOTION PLACED AT GROUND LEVEL.THE SCHEMATIC IS SHOWN BELOW.
5) DESIGN A CLOCK THAT SHOWS A SECOND HAND (ATLEAST) AND SHOULD RUN MINIMUM FOR 120 SECONDS WITH AN ACCURACY OF 10 SECONDS.USE OF GEARS , SPRING OR ANY ENERGY STORAGE ELEMENTS, ELECTRONIC CHIPS (OSCILLATOR ETC) IS NOT ALLOWED.
NOTE: - WEIGHT OF THE STONES WILL BE 250 GMS, 500GMS, 750 GMS.
