MY KNOWLEDGE ABOUT MECHANISMS
·Simple Machines: The simple machines are mechanical objects that helps us change direction or magnitude of a force.
There are 6 types of simple machines which are;
-
Lever: consists
of a rigid bar or beam that is allowed to rotate or pivot about a
fulcrum.
- Wheel and axle:consists of a wheel attached to a smaller axle so that these two parts rotate together in which a force is transfered from one to the
other.
-
Pulley: is
simply a collection of one or more wheels hich you loop a rope to
make it easier to lift things.
- Inclined plane:is a flat supporting surface tilted at an angle, with one end higher than the other, used as an aid for raising or lowering a load
- Wedge:is used to separate two objects or portions of an object, lift up an object, or hold an object in place.
- Screw:is a mechanism that converts rotational motion to linear motion, and a torque to a linear force.
·Simple Machines i use in my dialy life
We all do work in our daily lives and we all use simple machines every day.
I
normaly use these 4 simple machines that is the
fridge,microwave,dishwasher and the oven.
·Transmission
of movement
1.Linear motion: moving one way in a straight line
2. Reciprocating motion: moving backwards and forwards in an aro
3. Oscillating motion: moving backwards and forwards in an aro
4. Rotary motion: moving in a circle
Rack and Pinion
Gears are used to turn rotary motion into linear motion.
The pinion
is turned to move a flat gear.
Worm
drive and worm wheel
It changes the direction of rotation through 90º. The worm drive has only one tooth so it rotates faster than the worm wheel.
Bevel
gears
It changes direction of rotation through 90º. The teeth are angled at 45º so the gears fit together at right angles.
·Mechanisms
Is a
device designed to transform input forces and movement into a desired
set of output forces and the movement.
·
Cams
Is a rotating or sliding piece used especially in transforming rotary motion into linear motion or vice versa.
·
Gears
Gears are wheels with teeth that can either increase the speed of a machine or its force,but not both at the same time.
·Pulleys
The pulley is really a wheel and axle with a rope or chain attached. A pulley makes work seem easier because it changes the direction of motion to work with gravity.
·Uses
of mechanisms in our daily lifeThe
mechanisms that i use in my daily life are:
1. The Bicicle: The mechanism that the bicicle uses is called GEARS.
The
gears does the function of rotating the wheel so we can move.
2. The Car:In the engine there is a gear that allows the engine to function and a us to drive the car.
·Personal Interests
My personal interest and hobby is Music. I have my own drum set and drum room. I have been playing drums since i was the age of 7 as i liked it that much. I have only been 2 years in a drum school as i want to from my own band.
