O primeiro tipo de suporte que discutiremos \u00e9 um suporte de dobradi\u00e7a n\u00e3o deslizante (fixo). Esse suporte bloqueia o movimento horizontal (eixo x) e vertical (eixo y). No entanto, existe a possibilidade de rota\u00e7\u00e3o em torno da dobradi\u00e7a. \u00c9 por isso que ele \u00e9 chamado de piv\u00f4 articulado<\/strong> n\u00e3o deslizante. O c\u00edrculo na parte superior do tri\u00e2ngulo no qual as rea\u00e7\u00f5es s\u00e3o enganchadas \u00e9 a junta.<\/p>\n\n\n\nVoc\u00ea costuma perguntar se \u00e9 importante o sentido do feedback da rea\u00e7\u00e3o (o sentido para o qual a seta do vetor de for\u00e7a est\u00e1 apontando)?<\/p>\n\n\n\nPodemos fazer qualquer curva que quisermos, o importante \u00e9 manter uma dire\u00e7\u00e3o constante.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\nApoio m\u00f3vel<\/strong><\/h2>\n\n\n\nOutro tipo de suporte \u00e9 o suporte de piv\u00f4 deslizante. Nesse suporte, temos uma rea\u00e7\u00e3o na dire\u00e7\u00e3o vertical. \u00c9 nessa dire\u00e7\u00e3o que nenhum movimento \u00e9 poss\u00edvel. A dire\u00e7\u00e3o horizontal \u00e9 liberada, o que \u00e9 simbolizado pelo espa\u00e7o entre o solo e o suporte ou pelos c\u00edrculos que simbolizam a possibilidade de movimento.<\/p>\n\n\n\n\u00c9 poss\u00edvel que voc\u00ea encontre um suporte girado em algum \u00e2ngulo em suas tarefas. Ent\u00e3o, lembre-se de virar a dire\u00e7\u00e3o da rea\u00e7\u00e3o perpendicular \u00e0 base do suporte, como mostrei na figura acima.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\nEngaste<\/strong><\/h2>\n\n\n\nA restri\u00e7\u00e3o \u00e9 outro tipo de suporte que voc\u00ea pode encontrar. Aqui, al\u00e9m de bloquear o movimento nas dire\u00e7\u00f5es vertical e horizontal, a possibilidade de rota\u00e7\u00e3o no ponto de restri\u00e7\u00e3o tamb\u00e9m \u00e9 bloqueada. Na conten\u00e7\u00e3o, tr\u00eas graus de liberdade s\u00e3o retirados e, portanto, temos tr\u00eas rea\u00e7\u00f5es: horizontal, vertical e de momento.<\/p>\n\n\n\n
Engaste horizontalmente<\/strong><\/h2>\n\n\n\nO skate vertical \u00e9 um suporte muito menos comum em tarefas de mec\u00e2nica. O skate vertical tem dois graus de liberdade retirados por meio da rea\u00e7\u00e3o e do momento horizontais. Esse suporte n\u00e3o tem movimento ou rota\u00e7\u00e3o horizontal.<\/p>\n\n\n\n
Engaste verticalmente<\/strong><\/h2>\n\n\n\nO skate horizontal tamb\u00e9m tem dois graus de liberdade retirados dele, com a diferen\u00e7a de que ele tem rea\u00e7\u00e3o e momento verticais. Esse suporte n\u00e3o tem movimento e rota\u00e7\u00e3o verticais.<\/p>\n\n\n\n
Conjunto<\/strong><\/h2>\n\n\n\nE, por fim, a articula\u00e7\u00e3o. Quantos graus de liberdade a articula\u00e7\u00e3o retira? Como voc\u00ea pode ver na figura acima, h\u00e1 dois graus de liberdade. Rea\u00e7\u00e3o horizontal e vertical, como em um suporte de piv\u00f4 n\u00e3o deslizante.<\/p>\n\n\n\n
