Function is how the building will be used‚ form is how the building looks‚ and structures is how the building remains standing. Architects need to design structures that hold up under any combination of three physical forces; compression‚ tension‚ and bending. To days architects have a plethora of materials at their disposal‚ they benefit from the evolution of materials and have the opportunity to use them how they wish‚ but it has not always been this way. Primitive buildings were built using dry

toward the target of the anode. Central Beam- The theatrical center of the x-ray beam. The term is used to designate the direction of the x rays in a given projection; the central ray may be considered to extend from the focal spot of the x-ray tube to the film. Collimator- A lead disk with an aperture of various sizes and shapes the diaphragm limits the size of the primary beam to the area of interest‚ thereby minimizing patient exposure to the primary beam.

of temples was done with many rows of columns and beams and surrounding open courtyards to let light in‚ which is a typical Egyptian trabeation design. As the beams were made from Limestone they could only be a certain length due to the weight and the tension/strain that was going to be put on them. The columns had to be spaced close together so that the beams could rest half on the column‚ only just joining together so they could make a longer beam. Greece Greece mainly uses trabeation.

CHAPTER 1. 1.INTRODUCTION OF PLASTICS IN AUTOMOBILE Although the rate of usage of plastics in motor cars and commercial vehicles is increasing year by year‚ the actual percentage of plastics found in an average car is between 15-20%. However it is realized by both automobile and the plastic industry that this is just the beginning and the amount of plastics used in vehicles will treble in the next five years‚ at the expense of steel and its alloys. In essence the reason for the spectacular

Have you ever crossed a bridge when driving around your city and thought about how it was constructed or how long did it take to be built or is this bridge really safe and will it ever fall down. Well‚ I certainly have and I know that I don’t want for a bridge to fall down whenever I am driving or walking across one. It was 6:05 pm‚ the rush hour in Minneapolis‚ Minnesota and the unimaginable at the I-35W bridge occurred. On August 1‚ 2007 the 1‚907 foot long bridge collapsed leaving dozens of cars

If an object is relocated to an area with different gravity‚ such as a planet‚ the mass of the object will not change. Gravity has no effect on an object’s mass. 2. 2 Measure gravitational mass. 1 2 Finding mass with a triple-beam balance or a double-pan balance is a form of measuring gravitational mass. This is a static measurement‚ which means it is only accurate when the object being measured is at rest. A balance can measure weight and mass. Because the measurement of the
