Bridge Project Questions 1- History of Bridges In the beginning bridges were very simple structures that were built from easily accessible natural resources- wooden logs‚ stone and dirt. Because of that‚ they had ability only to span very close distances‚ and their structural integrity was not high because mortar was not yet invented and rain slowly but constantly dissolved dirt fillings of the bridge. Revolution in the bridge construction came in Ancient Rome whose engineers found that

Basic Research 1. What is a truss and how are trusses used in bridge design? Include the importance of triangular shapes in truss design. A truss is a formation produced by triangular components. The triangular units forming the truss are slim and straight in form. The truss bridges consist of a grouping of triangles. Trusses are used in bridge design to form a series of strong supports using triangles‚ and have the forces of tension and compression acting on them. The importance of triangular

Truss bridges have many advantages that make it more useful for everyday use. The truss bridge is very economical to build and uses very few resources. It uses light materials and small loads of timber or whatever it is being made of. It is also one of the stronger bridges that can be built. The trusses on top of the bridge make it very strong because the triangle shape takes away much of the pressure and spreads the pressure to the triangles and takes it away from the road part of the bridge.

Bridge Design Process In order to begin we must start our design process with the first step. We have to identify the need. The scenario is that we need to connect two pieces of land or structure so that a car must be able to pass through it. In this project we are to design and construct a bridge for a matchbox car. The bridge must be made of balsa wood and glue only. It must support its own weight‚ the load of the matchbox car‚ and additional weights that will be added. Next we must

Kovel World Theatre Greg Justice 07 November 2013 The View Unnerving. That’s the only way to describe walking into a dimply lit black box theatre to realize that the actor you have come to watch…is watching you. He’s acting‚ yes‚ but the whole premise of “The View” could not have been more clearly stated as we sat down to the crackle and pop of white noise in the background. In the tiny theatre‚ I couldn’t have been more than ten feet from what we were soon to learn was the main character‚ but

Alexander Tsiaras did an amazing video “From Conception to Birth” illustrating how an embryo develops into a child. Having gone through the process twice myself‚ reading through the prenatal chapter in “Child and Adolescent Development”‚ and then seeing it played out on screen was a unique perspective. The visualization of the fetus at 25 days with a heart chamber‚ 32 days with arms and hands developing‚ 36 days with the beginning of the vertebrae and 52 days with retina‚ nose and fingers‚ was

Evaluation for “the Flight from Conversation” Time flows; things change. The development of technology enables people to both access the world and people more rapidly. We immediately know the news that happen all over the world because of the Internet; we make friends with people thousands miles away through social networks; and we can have artificial intelligence or applications like SimSimi to accompany us when we are lonely. With time‚ these connections can start to replace real face-to-face
