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. 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. 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. 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. 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.
