Uma chaveta está sujeita a uma força tangencial de 12000 N. O eixo onde esta chaveta será montada possui diâmetro de 42 mm. Deseja-se utilizar na fabricação dessa chaveta o Aço ABNT 1045 (se = 400 MPa). O coeficiente de segurança a ser adotado no projeto é igual a 4, determinar o comprimento mínimo da chaveta para resistir aos esforços de cisalhamento. Dados: Largura da chaveta W = 12 mm e Altura H = 8 mm.
