1_DESCRIPTION (length, width, depth, composition and structural properties) AND PHOTO OF ALL MATERIALS PROVIDED

1200x3.2x90 mm Plywoodx1 1200x35x35 mm Pinex3

2_PHOTO AND DESCRIPTION OF ALL TOOLS USED 1. Electric drill: powerful, dangerous, and used to fix the screw into the relative hard materials.

2. Type measure: measure the length, flexible, can bend 3. Sliding bevel: can measure the certain angle, like 45째 and 90째.

4. Hammer: fix the nails and screws 5. Saw: cut the pine and ply into pieces 6. Screw vs. Brad: Screw is much stable than brad because the end of screw is larger than the body

4_PHOTO AND DESCRIPTION OF STRUCTURAL PERFORMANCE AND FAILURE MECHANISM OF ALL FOUR DESIGNS My team: we cut one pine wood into several small pieces and just put three of them under the whole structures (end of the bridge and the middle) because we don’t give space for plywood to bend so it is very easily to break in the middle part.

From the photo, it’s very clearly to see that all of the plywood is still complete whereas the pines are broken. There are two main reasons: 1.Plywood is very thin, screw can totally get through the wood while screw can just into the half depth of the pine, and it break the grain, so pine is easier to break than ply.

2. Plywood is flexible; it can bend under high pressure whereas pine is thick and uneasy to bend, so it’s easy to break, and cannot under high pressure

5_DESCRIPTION/DEFINITION OF THE FOLLOWING KEY CONCEPTS Span_: The full extent of something from end to end; the amount of space that something covers.

Cross Section_: A surface or shape exposed by making a straight cut through something, especially at right angles to an axis.

Strength_: The capacity of an object or substance to withstand great force or pressure.

Compression_: The reduction in volume (causing an increase in pressure) of the fuel mixture in an internal-combustion engine before ignition.

Tension_: A strained state or condition resulting from forces acting in opposition to each other.

Flexion_: The action of bending or the condition of being bent, especially the bending of a limb or joint.

Shear_: A strain produced by pressure in the structure of a substance, when its layers are laterally shifted in relation to each other.

Deflection_: The movement of a structure or structural member when subjected to a load.

Buckling_: [with object] bend (something) out of shape.

6_EXTRA NOTES AND COMMENTS About the teamwork: there are four people in our group, we cooperate, so two people use saw to cut the pine wood into short-length pieces: when one person is cutting, another people is using the type measure to measure the length; two people use electric drill and hammer to fix the support (short pine wood) and bridge together with screws.

About the position of screw: should leave some space, don’t put the screw at the edge of the material, or it’s very easy to destroy the materials when is getting in.

About the way of using hammer and electric drills: don’t be afraid!!! Hammer: use wrist instead of forearm.

About the safety: ALWAYS wear steel capped BOOTS!!!
