Leisure and technology - Essay Example In the contemporary world, things have taken a different direction especially after industrialization. The aspect of leisure time activities has been intertwined with technology. In most cases, the leisure-time mobility and activities have tended to develop through technology use (Castle, 2006). The technological aspects, which had previously been developed for military, scientific and commercial purposes, have shifted towards leisure-time use. Currently, new technologies concepts have a leisure-time use phase. Alternatively, technological devices tend to serve as prototypes for various models which are then adapted for leisure time use. New researches suggest that pervasive technological tools tend to be killing off leisure activities. The younger generation is the mostly affected by the aspect of technology and leisure. In most cases, students and the younger workers tend to work for longer hours hence taking shorter vacations. If they decide to go for the vacation, all they do is take their laptops, tabs and cell phones along. Most organizations also tend to encourage this aspect by recommending the use of internet to do organizational chores while on holiday. Examples of leisure activities, which have been affected by technology, include games, book reading among others. In the contemporary world, children and even the young adults prefer computer games during their leisure and not the real game on the ground (Castle, 2006). Football is nowadays played over the internet. Alternatively, people prefer to watch football or any other game on the television instead of going to the stadium to watch it live. Nowadays people do not spend their free time reading novels and magazines. With the introduction of the internet, most people prefer reading online articles and books. With modernization, traditional forms of leisure have been replaced

Estimating the Damping in a Single Degree of Freedom System Lab Report

Estimating the Damping in a Single Degree of Freedom System - Lab Report Example The movements include free response and forced response. Free response is made as a result of initial conditions while forced response is made as a result of outgoing input to the system. Free response in this context consists of oscillations at a particular frequency which is natural. When there is no dumping in the situation, the oscillation continues in the system indefinitely. When there is dumping, the 1 Degree of Freedom undergoes decaying oscillations. Forced response in 1 Degree of Freedom consists of vibrations that occur at a frequency which is majorly dictated by the input of force. Force response increases when there is also an increase in input. When there occur an initial transient portion of response, the steady state response contains an oscillation which is at the same frequency as the input. The amplitude and phase in this situation depend on the frequency of input. The main requirements in the experiment include an oscilloscope, a potentiometer, a variable dumping unit, a digital weighing scale, a helical spring and signal amplifier, Experiment can be carried out for a free a free vibration and forced vibration. For this laboratory, a mechanical strip-chart recorder is to be used to capture the free vibration motion of a simple single-degree-of-freedom system. The strip-chart recorder consists of a marking pen a fixed to amass carriage, which is movable in the vertical direction, and a continuous strip of paper which, when driven by a rotating drum, moves in a horizontal direction past the pen. A drawing of the single-degree-of-freedom system, with the strip-chart record The forced vibration will be provided by a shaker, which is driven by a sine wave function generator. The system is attached to the shaker plate and then forced into motion. The motion is sensed using two accelerometers, one attached to the base and one attached to the upper portion of the system.
