(AFA - 2015) JOBS OF THE FUTURE There is no future in any job. The future lies in the person who holds the job. George W. Crane One of my primary complaints with higher education is that they tend to prepare students for jobs of the past. Similarly, the best paying jobs of the future are all jobs that currently exist today. Many of them1will stillexist in the future, but with some changes as technology and communication systems make their impact As a rule of thumb, 60% of the jobs 10 years from now havent been invented yet. With that in mind, Ive decided to put together a list of some jobs that will bein high demand in the future. Jobs before 2020 Many of the changes we see today will causenew jobs to materialize quickly. This first section deals with new positions that will likely2be developed within thenext 10 years. 3D printing engineers Classes in 3D printing are already being introduced into high schools and the demand for printer-produced products will rise3quickly.The trend will be for these worker-less workshops to enter virtually different fields, at the same time, driving the need for competent technicians and engineers todesign and maintain the next wave of this technology. Nano-medics Health professionals capable of workingon the nano-level, both in designing diagnostics systems, remedies, and monitoring solutions will be in highdemand. Organ agents The demand for transplantable organs is exploding4and people who can track down and deliverhealthy organs will be in hot demand. Octogenarian service providers As the population continues to age5we will have record numbers of peopleliving into their 80s, 90s, and 100s. This growing group ofactive oldsters will provide a demand for goods andservices currently not being addressed in todaysmarketplace. Jobs in 2030 and beyond A number of technologies currently on thedrawing board will require a bit longer lead time beforethe industry comes into its own. Here are a few examplesof these kinds of jobs: Body part limb makers The organ agents listed before will quickly find themselves out of work as soon as we figure out how to efficiently grow and mass produceour own organs from scratch. Earthquake forecasters While scientists are developing skills to work with nanoscale precision on theearths surface, the best we can know about below the surface is blindfolded guesswork done with 100-mileprecision. What we dont know is literally killing us over 226,000 killed6in 2010 alone. But that will change overtime as we begin to understand the inner working of the earth and accurately forecast when the next big quakes are about to hit Heavy airengineers Compressed air is useful in a wide variety of ways. However, we have yet to figure out how to compress streams of air as they pass through our existing atmosphere. Once we do, it will create untold opportunity for non-surface based housing andtransportation system, weather control, and other kinds of experimentation. Final thoughts The jobs and occupations listed above are justscratching the surface7. This list is intended to help stretch your imagination and start you down a pathof imagining your own future.

(AFA - 2015) Uma determinada caixa transportada em um caminho que percorre, com velocidade escalar constante, uma estrada plana e horizontal. Em um determinado instante, o caminho entra em uma curva circular de raio igual a 51,2 m, mantendo a mesma velocidade escalar. Sabendo-se que os coeficientes de atrito cintico e esttico entre a caixa e o assoalho horizontal so, respectivamente, 0,4 e 0,5 e considerando que as dimenses do caminho, em relao ao raio da curva, so desprezveis e que a caixa esteja apoiada apenas no assoalho da carroceria, pode-se afirmar que a mxima velocidade, em m/s, que o caminho poder desenvolver, sem que a caixa escorregue
