This paper purpose is to analyze one of the main problems faced by cold rolling industry of the current time, the mechanical vibration. Factors such as strips with high velocity in order to increase the productivity and thickness becoming thinner and thinner cause the vibrations to be present at all times during rolling. These market requirements also drive the industry for technology development and thus bring the challenges that the operation of a new modern equipment and more powerful. The initial purpose is to analyze the forces that cause vibration in a rolling mill type four high with two stands, where is desirable to identify the origins of these vibrational forces to make possible dismiss them or at least control its intensity, in order to prevent damage in the rolling mill and ensure product quality to the customer. For it, will be used instruments to record and store the vibrations that occur during the lamination process. With this data will be able to analyze the characteristics of the vibrations and act at your elimination. At the end of the work is expected to demonstrate how important the critical view of the engineer in the analysis of graphics combined with the calculations of the natural vibration frequency and engagement of key parts of the laminator. With these two tools at hand, will be possible to increase the productivity of the rolling mill and act preventively in maintenance, thereby reducing your downtime and increasing its performance and efficiency

The housing issue in Brazil is'nt a recent problem and has been discussed, worked and questioned in the institutional framework, especially with regard to the critical considerations on the topic and urban problems involved. We as milestones in the Brazilian housing policy the National Housing Bank - BNH, 1964, the height of the military regime in Brazil, and the Minha Casa, Minha Vida, in 2009. Both have questions that approach and distance themselves regarding changes in the Brazilian housing policy, where we have the emergence of new forms of knowledge production and housing consumption. Thus we have a number of advances in ways of acquiring social housing, even at different times, it is characterized as capitalist forms of this issue. Thus the spatial process of housing developments arising from these programs reflect the change in space - time that they lay down, turning the urban space of the cities in this case the city of Presidente Prudente / SP
