LINEAR AIR TRACK
TRIANGULAR SECTION ALLOY TRACK, LENGTH
255 CM ,WITH STAGGERED AIR HOLES .SUPPORTED ON TWO LIGHT ALLOY CASTINGS
POSITIONED 45 CM FROM EACH END OF THE TRACK. ONE SUPPORT HAS A TWO POINT
CONTACT AND OTHER A ONE POINT CONTACT FOR LATERAL AND HORIZONTAL ADJUSTMENTS
FOR WHICH A KNURLED SCREW IS PROVIDED .LARGE CATAPULT ARMS WITH SLOTS FOR
ELASTIC BANDS ARE FITTED TO EACH END OF THE TRACK.A PULLEY FITTED TO ONE END
OF THE TRACK ENABLES EXPERIMENTS INVOLVING ACCELERATION UNDER A CONSTANT
FORCE TO BE INVESTIGATED.IDENTICAL END CAPS ENABLE AIR TO BE INTRODUCED FROM
EITHER END OF THE TRACK,BUNG BEING SUPPLIED TO CLOSE THE END NOT BEING USED.
THE VEHICLES BUFFER ATTACHMENTS AND CLAMPING SCREWS ARE MATT BLACK TO HELP
INTERPRETATION OF STROBOSCOPIC PHOTOGRAPHS.

TICKER TAPE TIMER A.C.
OPERATES ON 12V AC .THE TIMER EMPLOYS ELECTROMAGNET WITH SPRING LOADED
ARMATURE WHICH VIBRATES ABOVE A SUPPORT TABLE FOR A CARBON PAPER DISC, PAPER
TAPE,DRAWN THROUGH GUIDES ON THE TABLE ,IS STRUCK BY A DOTTING SCREW CARRIED
ON THE ARMATURE .THE PEG ON THE SUPPORT TABLE IS MOVABLE TO ALLOW MAXIMUM
USE OF CARBON PAPER DISC. SUPPLIED WITH 90 METER ROLL OF TAPE AND CARBON
PAPER DISCS. THE TICKER TAPE TIMER PRODUCES DOTS SPACED AT 1/50 OR 1/60 SEC
INTERVALS DEPENDING ON MAIN FREQUENCY .ADDITIONAL BONUS WITH EXTRA GUIDES
ACCOMODATES 4.5 MM EXTERNAL DIAMETER RUBBER TUBING FOR THE ' PEARLS IN AIR '
WATER DROP EXPERIMENT. POWER SUPPLY 12 V/ AC . |

FALLING BODIES
APPARATUS
TO DEMONSTRATE THAT A BODY IMPELLED HORIZONTALLY WILL HAVE VERTICAL
ACCELERATION SAME AS THAT OF A BODY FALLING FREELY. TWO 19MM DIA STEEL BALLS
ARE LAUNCHED BY RELEASING A PUSH BUTTON .THIS PROJECTS ONE BALL FORWARD AND
THE OTHER FALLS FREELY.THIS MECHANISM IS MOUNTED ON A WOODEN BLOCK ( 180 X
60 X 30 MM ).

'
g ' BY FREE FALL APPARATUS
THIS APPARATUS CONSISTS OF A SOLENOID ( FOR PROMPT RELEASE OF THE SPHERE ON
BEING DISCONNECTED ) AND GATE SWITCH UNIT MOUNTED ON A BASE WHICH IS CLAMPED
ON A 12 MM DIAMETER RETORT STAND ROD. CONNECTIONS ARE MADE THROUGH 4 MM
SOCKETS ,THE GATE SWITCH UNIT CONSISTS OF A HINGED METAL PLATE HELD AGAINST
AN ADJUSTABLE CONTACT BY MEANS OF SMALL PERMANENT MAGNET SO THAT BY PROPER
ADJUSTMENT THE PLATE FALLS PROMPTLY AT THE IMPACT OF THE FALLING SPHERE.
CENTI SECOND TIMER CAN BE USED WITH THIS APPARATUS
