Este artigo explica o que s\u00e3o for\u00e7as angulares. Al\u00e9m disso, voc\u00ea encontrar\u00e1 v\u00e1rios exemplos deste tipo de for\u00e7as e como \u00e9 calculada a for\u00e7a resultante de duas for\u00e7as angulares. <\/p>\n

<\/span> O que s\u00e3o for\u00e7as angulares?<\/span><\/h2>\n

For\u00e7as angulares<\/strong> s\u00e3o for\u00e7as que atuam no mesmo ponto e formam um \u00e2ngulo. Portanto, as dire\u00e7\u00f5es de duas for\u00e7as angulares tamb\u00e9m formam um \u00e2ngulo.<\/p>\n

Na f\u00edsica, quando duas ou mais for\u00e7as angulares s\u00e3o aplicadas a um corpo, ele \u00e9 chamado de sistema de for\u00e7as angulares<\/strong> . <\/p>\n

\n
\"for\u00e7a<\/figure>\n<\/div>\n

Portanto, por defini\u00e7\u00e3o, duas for\u00e7as angulares s\u00e3o igualmente concorrentes ao mesmo tempo. No entanto, duas for\u00e7as angulares nunca podem ser paralelas ou colineares. <\/p>\n

<\/span>Exemplos de for\u00e7as angulares<\/span><\/h2>\n

Para que voc\u00ea possa entender melhor o significado das for\u00e7as angulares, a seguir est\u00e3o dois exemplos reais desse tipo de for\u00e7as.<\/p>\n

Um exemplo de for\u00e7as angulares \u00e9 um objeto sustentado no teto por v\u00e1rios cabos. Se os cabos n\u00e3o forem paralelos, as for\u00e7as que atuam no objeto ter\u00e3o algum \u00e2ngulo e, portanto, ser\u00e3o angulares. <\/p>\n

\n
\"exemplo<\/figure>\n<\/div>\n

Outro exemplo de for\u00e7as angulares \u00e9 quando um objeto \u00e9 puxado por uma rampa usando uma polia. No caso mostrado abaixo voc\u00ea pode ver como diversas for\u00e7as atuam sobre o objeto e, por exemplo, a tens\u00e3o exercida pela corda (T) e a for\u00e7a normal (N 1<\/sub> ) s\u00e3o angulares. <\/p>\n

\n
\"\"<\/figure>\n<\/div>\n

<\/span> For\u00e7a resultante de for\u00e7as angulares<\/span><\/h2>\n

Um sistema de for\u00e7as angulares pode ser substitu\u00eddo por uma for\u00e7a resultante<\/strong> . Desta forma, o sistema \u00e9 simplificado, pois em vez de haver duas (ou mais) for\u00e7as, existe apenas uma for\u00e7a no sistema.<\/p>\n

Quando as duas for\u00e7as angulares formam um \u00e2ngulo de 90\u00ba, \u00e9 f\u00e1cil calcular o m\u00f3dulo da for\u00e7a resultante, bastando aplicar a seguinte f\u00f3rmula: <\/p>\n

\n
\"soma<\/figure>\n<\/div>\n

Por exemplo, se soubermos que duas for\u00e7as de 4 N e 3 N s\u00e3o perpendiculares, a magnitude da for\u00e7a resultante ser\u00e1:<\/p>\n

\n

\"\\begin{aligned}\\begin{vmatrix}<\/p>\n<\/p>\n

Contudo, quando as duas for\u00e7as formam um \u00e2ngulo diferente de 90\u00b0, \u00e9 mais dif\u00edcil determinar a for\u00e7a resultante. Voc\u00ea pode ver todos os casos poss\u00edveis explicados no seguinte artigo: <\/p>\n
