In our experiments, we studied the classical dynamic of a particle in vertical motion subject to a constant gravitational field and the partial shock with an elastic wall with oscillatory motion located below the particle. The motion of the particle was confined to the vertical direction by a glass guide tube, which was initially evacuated, allowing viscous drag forces to be disregarded. The time between impacts, as well as the time between the reference phase of the movement of the base and the moment of impact and the period of oscillation of the base will be acquired by a hardware and software to obtain the phases space to be compared later with the description of the system through mapping discrete variables via the 'particle velocity immediately after shock 'and' phase of the movement of the base at the instant of shock 'obtained by computer simulation. This requires developing an electronic analog system followed by Digital implemented in reconfigurable logic, more specifically a sequential machine able to discriminate the impact with the metal base from the impacts of the glass guide tube, based on the frequency spectrum of the response of the microphone to these different impacts

Carnival is a unique opportunity for the associations demonstrate the community’s annual work and the float is a major component of this celebration, responsible for pitch the samba using allegories and carry important figures. The excess weight of the floats which are mostly manufactured from truck and bus structures requires larger amount of people to push the vehicle in addition to increased efforts on the steering systems, suspension and wheels, raising the probability of breakage and loss of one year work. The objective of this study is to use the concepts of strength of materials combined with computer simulation to obtain a structure that has the lowest possible weight without compromising the safety of transported components and that is also easy to manufacture, drive and store
