Uma viga uniforme de massa 120 kg e 5,0 m de comprimento é sustentada, sem está
fixada, pelas duas pilastras mostrada na figura abaixo, distante 3,0m uma da outra. Uma
pessoa de 50 kg começa a caminhar ao longo da viga.
Quanto ele pode se afastar da extremidade esquerda da viga sem que ela tombe?

10. Exemplo 02
Suponha que, para arrancar um mourão fincado no chão, um homem, puxando -o
diretamente com as mãos, tivesse de exercer nele uma força de intensidade 1800 N, no
mínimo.
Observe a figura
Usando uma viga amarrada no mourão e apoiada em uma tora, como indica a figura, determine a
mínima intensidade da força que o homem precisa exercer na viga para arrancar o mourão. Para
simplificar, desconsidere o peso da viga e suponha que a força total exercida nela pelo homem esteja
aplicada no ponto médio entre suas mãos.

Uma escada homogênea, apoiada sobre um piso áspero, está encostada numa
parede lisa. Para que a escada fique em equilíbrio, as linhas de ação das forças que
agem sobre a escada devem convergir para um mesmo ponto Q.

31. —Someone Famous
“Everyone makes mistakes. That
is why there is an eraser in every
pencil. When in doubt, rub it out!”

32. Conclusions
Rubber erasers are the best there could be: they wipe mistakes out!
#NationalRubberEraserDay is actually a big thing in the U.S.
Our research was unable to find the creator of the Eraser Day
April 15, 1770, marks the founding of the rubber eraser
It’s OK to make a mistake or two. Find your eraser to fix them!
Artists, writers, students and accountants find erasers as handy
We all make mistakes while holding a pencil in our hand
Nowadays, we can erase our mistakes away… Thankfully
