What are the three types of structures in statics?
I - Hypostatic structures are those whose number of support reactions or links is less than the number of equations provided by the equilibrium conditions of statics.
II - Isostatic structures are those whose number of support reactions or links is equal to the number of equations provided by the equilibrium conditions of statics.
III - Hyperstatic structures are those whose number of support reactions or links is greater than the number of equations provided by the equilibrium conditions of statics.
a) Only I is correct.
b) Only II is correct.
c) Only III is correct.
d) I and II are correct.
e) I, II, and III are correct.

A resposta correta é a alternativa "d) I and II are correct." As três estruturas em estática são: I - Estruturas hipostáticas são aquelas cujo número de reações de apoio ou ligações é menor do que o número de equações fornecidas pelas condições de equilíbrio da estática. II - Estruturas isostáticas são aquelas cujo número de reações de apoio ou ligações é igual ao número de equações fornecidas pelas condições de equilíbrio da estática. III - Estruturas hiperestáticas são aquelas cujo número de reações de apoio ou ligações é maior do que o número de equações fornecidas pelas condições de equilíbrio da estática.
