Science Test Unit 2 Study Notes Term Definition Static Load A static load is a structure whose size, position, and direction will not change. Dynamic Load A Dynamic Load is a force that can change when acting on a structure(e.g., Snow) Internal Force An Internal Force is a force that acts within the structure. (Ex. compression, shear, torsion, tension) External Force An external Force is a force that acts on an object or structure from the outside.(Ex. Gravity, wind, water) Form Form is the shape, size, and material of a structure.. Function Function is the purpose or ability to do something. Force A force is any push or pull motion. A force acts on all structures. Shear Shear is the force that pushes in opposite directions. Torsion Torsion is a force in a twisting motion. Tension Tension is a stretching force that expands or lengthens. Compression Compression is a force that squeezes or presses something together. Sensor A sensor is any device that can detect or measure a certain condition. (Ex. Heat sensor, light sensor, and smoke sensor) Ergonomics Ergonomics is people’s efficiency in their working Symmetry Symmetry is when an object is the same on both sides. In structures, symmetry also refers to a general sense of balance and harmony Aesthetics Through the process of Photosymphisis, producers can create energy they can use to grow. This energy is then consumed by consumers Line Of Symmetry A line of symmetry is an imaginary line that can go in any direction, as long as the part of the object on both sides is reflected Suspension Bridge A suspension bridge is a bridge that uses cables suspended from towers to support the load Beam Bridge A beam bridge is a bridge that consists of a horizontal beam supported by piers Arch Bridge An arch bridge has a semicircular shape to support the load. It uses retaining walls (abutments) for additional support. Truss Bridge A truss bridge is a bridge that is similar to a beam bridge, except this bridge has a brace that is made from triangles to provide extra support “Form Follows Function” “Form Follows Function” is the principle in architecture and industrial design, stating that the shape of a structure should primarily relate to its intended function or purpose Frame Structure A building with a “skeleton”(metal frame) that holds the building up. Examples of this are Apartments/condos, skyscrapers and some bridges Shell Structure A building that is hollow on the inside, but has a strong outside/shell like an egg. Examples of this are sports domes,igloos and the Sydney Opera House. Solid Structure A solid structure is a structure with no or little space inside it.Examples of this structure are bricks and block Magnitude The power of a force.Example:
