Mini project 2 - Assignment ExampleFrom picture 1, there ar two main loads that acting on the bridge. These are 1.Dead load,This refer s to the permanent charge of both the body structured and non structure component of the bridge. This include the roadway used by the vehicle on the object , sidewalk and the attached equipments. Dead loads on a bridge are establish on material unit and are based on material unit and are of ceaseless magnitude.On designing a bridge dead load, must be estimated. In order to counteracted the issue effects of the external loads, it is good to compute the final dead load of individual portions of the bridge structure before designing the final supporting members.This refers to the pack of the vehicle that picky the bridge. Each of these individual vehicles comprises of a series of concentrated moving loads that vary in spacing and magnitude. When the loads move, a function of changes are generated in shears, reaction and moments in the members of the structure. The extent of these resultant forces depend on the number of spacing, weight and the position of the loads on the span. To produce the maximum impacts for each stress, the designer must position the track vehicle loads well.From picture 1, it is true that when a piece of material e.g. steel or a steel reinforced concrete is stressed by a force of granite due to the load of the vehicle, the cross sectional material does several things. In general the top must compress compression forces and the bottom must stretch Tensional forces. This gives rise to the following stresses as shown in the picture 1.This is the stress that
