Truss Bridge Physics 141 Robin Hoffmeister There is many reason that we need bridges in every day of our life‚ from sufficient means to pass over a roadway‚ waterway‚ railway‚ or other structure. You don’t even think about them because it takes no effort to get over them and they are just there for your use. So if you don’t think of them for everyday use I highly doubt that you would think of the physics that is involved in putting one together or the kind of force the bridge can actually

Truss Construction Shop is a company that produces cost-effective trusses with the promise of “cutting edge” construction technology. Recently‚ the company experienced a workplace accident that resulted in an employee being seriously injured. It is now the company’s responsibility to investigate how and why this accident occurred and how to prevent it in the future. The accident has created some concerns for employees and customers. The company must now work to ensure the employees’ safety is the

Grabber: Truss bridges are a good creation because it helps with traveling since it is a sturdy and cheap efficient bridge to make. Define truss bridges and explain how they are different from other bridges: A truss bridge is a bridge whose load-bearing super structure is composed of a truss‚ a structure of connected elements forming triangular units. The connected elements are typically straight. The truss bridge is different because it uses triangles‚ its way brought about in the 19th and 20th

The Pratt Truss was designed by Thomas and Caleb Pratt in 1844. It became popular for railway bridges because it made good use of iron. The Pratt has many variations‚ most with their own unique name. For instance‚ the Baltimore‚ Pennsylvania‚ and the Parker are all based off the Pratt. Pratt Truss How the forces are spread out Here are two diagrams showing how the forces are spread out when the Pratt Truss is under a load. The first shows the load being applied across the entire top

Why do you think our school is good for your future plans andpurposes? A simple bridge truss was the first structure I ever analyzed . The simplecombination of beams that could hold cars‚ trains‚ and trucks over long spansof water fascinated me . Having the tools to analyze the loads on the trussfurther increased my interest in structures . I encountered the bridge in atextbook for my first engineering class . Knowing that the professor‚ Mr . John Doe‚ was a tough teacher‚ I asked himfor th

Bridge Failure Studies and Safety Engineering 2.1 HISTORY OF DISASTERS AND SAFETY MANAGEMENT 2.1.1 Unexpected Material Deterioration and Failure Engineering is usually about avoiding failures and investigating why failures occur and ways to fix the problem. There is a need to understand the conditions giving rise to past failures and ways to avoid such failures so that loss of life can be minimized. Historical events and selected case stud-ies demonstrate the causes of

LAB REPORT Pin Jointed Frame 1312800 1st year school of engineering University of Warwick Date Submitted: 8/01/2014 Summary In this experiment the main aim was to modelling a frame subjected to multiple loading conditions and record how the force and strain vary to different loads. The frame represented a simple roof trusses and the loading conditions are similar to what a typical roof would undergo. In this experiment a universal fame was used with load cells
