Building a bridge from Balsa wood is such a popular educational
activity that there are competitive contests for building model bridges. A balsa
wood bridge-building project touches on principles of building and construction
trades, engineering, physics and static equilibrium. The main goal of building a
balsa wood bridge is to construct a bridge that withstands the greatest amount
of force before falling. Competition balsa wood bridges have been constructed
that hold up to stresses greater than 400 lbs.
Instructions
Design Your Bridge
Sketch out a rough design for your bridge on paper. These sketches will help
you develop different ideas of bridge design before you begin to cut your balsa
wood. Your design should have a superstructure and a substructure. This view
does not have to be to bkqsfahq scale, since it is only a rough design. One
style of bridge that many designers use is the Warren truss style, which is
favored by railroads for its load-bearing capabilities.
Sketch a three-view sketch, which will include views of your bridge from the
top, sides and end. Draw this sketch to size, using the graph paper to ensure
your measurements are precise. Since your wood is 1/8 inch wide, your structure
should have 1/8-inch-wide trusses. The bridge should also be open enough that
you can push a simulated vehicle across the bridge span.
Sketch out your bridge nodes in larger-than-life detail. Nodes are the points
of connection where your bridge will endure stress. Stress points are the most
probable point of fracture for your bridge when it is put under testing
conditions. Attention to details, such as factoring in how to cope with stress
along the nodes, is the key to a successful bridge design.
Attach your three-view drawing to a hard surface, such as a piece of
cardboard. You will build your bridge on this surface using your drawing as a
guide. Over this, tape the wax paper. The wax paper will prevent you from
accidentally gluing your project to your guide.
Cut the pieces of wood so that each piece fits the outline of the bridge
you've drawn. To ensure a perfect fit, cut each piece of wood slightly longer
than the guide. Then line up the wood with the guide, and trim it to match.
Pin the pieces of wood in place, then glue them together. Once the major
trusses are glued in place, glue in the secondary trusses. Wait until all glued
spots are dry before removing pins and setting aside your bridge's sides.
Repeat the previous step to build your bridge's cross braces. Once the cross
braces have dried, attach them to the sides at the roadway and the top of the
bridge. Use clothespins to hold the bridge and cross braces together while they
dry.
Check all the nodes to ensure they are tightly in place once all the glue has
dried on your bridge. Your bridge is now ready to be graded.If you want to know

You should cut it very carefully since it may affect the flight. When you cut your pattern, you are advised to use a new blade in a modeling knife.
Third, balance is very important to a plane or glider. You should correct it or balance it if your balsa wood glider seems not balance when flying. You can cut slightly from the fuselage rear to reduce its weight if the nose of the glider is too heavy.
Fourth, you should mark your glider. In order to make it easier for you to see your glider when it fly on the sky, you should spray some colorful paints on the wing an tail of your glider. You can mark a special image or name or number you like. Also, you are advised to throw your glider straight ahead. You should control your strength when throwing your glider since too gently or too hard will be not good to control your glider.

There Are Various Blasa Wood Model In Our Daily Life
We may remember our childhood times with the balsa wood gliders. When you have
one,your friends can be so envy that they are more likely to play with you all
day long. Balsa wood gliders brought great fun when it is our youth. It is also
there that the balsa
wood toys. They are light enough to operate and more perfect with the latest
technology. In addition,balsa wood has been used in broader fields and areas at
home and abroad.
In the history,though ideal offered wood and fiber board RTF gliders are sold at an inexpensive price by any means,these can probably be considered some of the fore-runners of our "toy" airplanes. Many youngsters loved to fly toy airplanes,but the lack of the building skills necessary to assemble those marvelously complicated balsa wood stick and tissue kits that prevents the play. So these "ready-to-fly" (RTF) balsa wood toys provided an easy way for us to enter the realm of flight.
During the World War 2,balsa wood was considered to be a "strategic material" that toy airplane production was reduced dramatically. After the war,balsa once again became plentiful. As the post-war economy and family production boomed,dozens of companies now competed in the toy airplane market. The number and variety of toy airplanes was truly dazzling. New and important entrants into the RTF glider market.
Frankly speaking,balsa wood is popular in the construction fields as well as RTF glider market. They are light and easy to be assembled. It has many other properties. What is more it can be available in various market and online stores. You are advised to surf the Internet for the balsa wood because there are rich resources to be selected. You can compare those types and specifications as well as the price. Have the intent,you can visit the website:www.balsafactory.com More detailed information and super service can be given to you.

Why To Select Balsa Wood For Model Building?
IS BALSA THE LIGHTEST WOOD IN THE WORLD?
No! Most people are surprised to hear that botanically, Balsa wood is only about the third or fourth lightest wood in the world. However, all the woods which are lighter than balsa are terribly weak and unsuitable for any practical use. The very lightest varieties don't really resemble wood at all, as we commonly think of it, but are more like a tree-like vegetable that grows in rings, similar in texture to an onion. It is not until balsa is reached that there is any sign of real strength combined with lightness. In fact, balsa wood is often considered the strongest wood for its weight in the world. Pound for pound it is stronger in some respects than pine, hickory, or even oak.
SELECTING BALSA FOR MODEL BUILDING?
Most hobby shops have a large rack of balsa sheets, sticks, and blocks that you can choose from if you are going to build a model airplane from scratch. Undoubtably, because of the nature of balsa, the actual weight of each piece of wood of the same size can vary slightly. When you select the pieces you want to buy you should keep their final use in mind. Logically one should select the lightest grades for the lightly stressed model parts (nose blocks, wingtip blocks, fill-ins, etc.) and the heavier grades for important load bearing parts of the structure (spars, fuselage stringers, etc.). To a large extent, this selection is already partly done for you. Here at SIG, we purosely cut up our lightest raw balsa into blocks, and our hardest raw balsa into sticks. Sheets are cut in the entire wide range of density.

Make Balsa Wood Plane With Proper Tools
In order to make a balsa wood plane, you will need to
select the suitable tools and qualified balsa wood s. Generally, you need to
prepare a knife with sharp blade, the balsa wood glue, pins, a pen to make
marks, a steel ruler and a few papers to draw your design. In order to make the
task easier, you should make sure that the blade is sharp enough to cut the
balsa wood straightly.
Step 1
Draw your design on the papers. You can draw each part of the plans and record the sizes of them. Different types of balsa wood planes are endowed with different designs. For example, you need to design several wings and a small body for the helicopter while the airplane is characterized by a huge body and two wings.
Step 2
Cut the balsa wood according to your design. Make obvious marks on the balsa wood where need to be cut. Cut straightly along with the marks and avoid to use too much force to destroy the balsa wood. Collect the scraps and clean your working platform after cutting.
Step 3
Assemble the balsa wood plane. Glue the parts together and in order to make a tight connection, you may need to hold the glued parts together for a few minutes. You will need to use the pins to form a stable structure. The parts where need to bear the weight of the plane should be connected with the pins.
