  3. 3. BRIEF INTRODUCTION OF PROJECT PEDAL–POWERED HACKSAW METAL CUTTER AND WASHING MACHINE Introduction The power hacksaw machine, which runs on electric power, works on the principle of the conversion of rotational motion to oscillatory motion. The bicycle also uses the same principle. To give shape to his idea, firstly buy an old bicycle from a scrap market, then cut the pedals of the bicycle from 12 cm to 8 cm and welded it as per requirement and re-affixed the pedals to it. To use a guide to control the hacksaw blade which is used to cut the metal. Metal slabs were fitted on the hacksaw blade to ensure pressure on the object to be cut and linear movement of the blade. A clamp, with 360 degree rotation, was fixed to hold the metal pieces while cutting, and to allow them to be cut in any shape and angle. Since a lot of energy is produced during the pedalling process, we will envision utilising it productively. We will fix a dynamo and a 12-volt battery to store the energy. To transfer the energy generated from dynamo to the battery, a forward-biased diode will use. The saved energy can be use to light a 12-volt bulb, which comes in handy while working in the dark. Since a lot of energy is produced during the pedalling process, we will envision utilising it productively. We will use the rotation of the cycle to rotate the attached bucket(PEDAL POWERED WASHING MACHINE).

  6. 6. MATERIAL REQUIRED IN THE PROJECT 1) SCRAP COMPONENTS OF BICYCLE 2) ALUMINIUM STRIP 3) SQUARE TUBE 4) HACK SAW 5) NUT BOLT 6) DYNAMO 7) BATTERY 8) PLYWOOD 9) POWER SUPPLY BLOCK 1) DYNAMO Dynamo is an electric device that runs on direct mechanical input. Dynamo were used by running machinery, often eliminating the need for a local steam engine or internal combustion engine. Dynamo can use directly to recharge batteries, providing the motive rotation .
  7. 7. 2) ALUMINIUM STRIP WITH HOLES Sheet metal is simply metal formed into thin and flat pieces. It is one of the fundamental forms used in metalworking, and can be cut and bent into a variety of different shapes. Countless everyday objects are constructed of the material. Thicknesses can vary significantly, although extremely thin thicknesses are considered foil or leaf, and pieces thicker than 6 mm (0.25 in) are considered plate. And holes were cut by blanking process in an organized manner. 3) SQUARE TUBE Hollow square tube, which have a uniform cross-section with only one enclosed void along their whole length in the shape of rectangles (including squares), and which have a uniform wall thickness.
  8. 8. 4) HACK SAW A hacksaw is a fine-tooth hand saw with a blade held under tension in a frame, used for cutting materials such as metal or plastics. Hand-held hacksaws consist of a metal arch with a handle, usually a pistol grip, with pins for attaching a narrow disposable blade. A screw or other mechanism is used to put the thin blade under tension. The blade can be mounted with the teeth facing toward or away from the handle, resulting in cutting action on either the push or pull stroke. On the push stroke, the arch will flex slightly, decreasing the tension on the blade, often resulting in an increased tendency of the blade to buckle and crack. Control of the cut and longer blade life. 5) NUT BOLT In normal use, a nut-and-bolt joint holds together because the bolt is under a constant tensile stress called the preload. The preload pulls the nut threads against the bolt threads, and the nut face against the bearing surface, with a constant force, so that the nut cannot rotate without overcoming the friction between these surfaces. If the joint is subjected tovibration, however, the preload increases and decreases with each cycle of
  9. 9. movement. If the minimum preload during the vibration cycle is not enough to hold the nut firmly in contact with the bolt and the bearing surface, then the nut is likely to become loose. 6) SWITCHES DPDT (double pole, double throw): A DPDT switch routes two separate circuits, connecting each of two inputs to one of two outputs. A DPDT switch has six terminals: two for the inputs, two for the A out puts, and two for the B outputs. 7) PLYWOOD Plywood layers (called veneers) are glued together, with adjacent plies having their wood grain at right angles to each other, to form acomposite material. This alternation of the grain is called cross-graining and has several important benefits: it reduces the tendency of wood to split when nailed at the edges; it reduces expansion and shrinkage, providing improved dimensional stability; and it makes the strength of the panel consistent across both directions. There is usually an odd number of plies, so that the sheet is balanced—this reduces warping. Because plywood is bonded with grains running against one another and with an odd number of composite parts, it is very hard to bend it perpendicular to the grain direction.
