1806 O. G. Gregory Treat. Mech. I. i. ii. 24 Resolve each of the forces into components respectively parallel to these co-ordinates.

1806 O. G. Gregory Treat. Mech. I. i. ii. 25 The two components of the resultant R referred to the same axis, are evidently R cos. r and R sin. r.

1883 Encycl. Brit. XV. 699/1 It is very generally convenient to resolve forces into components parallel to three lines at right angles to each other, each such resolution being effected by multiplying by the cosine of the angle concerned.

1957 B. I. Bleany & B. Bleaney Electr. & Magn. (1963) xx. 546 Each vector makes a constant angle with this direction, and the component of the angular momentum in this direction is therefore constant.

4. Physical Chemistry. Each of the constituents of a system which are not necessarily identified individually but are defined as equal in number to the minimum number of species required to define the composition of the system.

1876 J. W. Gibbs in Trans. Connecticut Acad. Arts & Sci. III. 124 The component substances S₁, S₂,..Sn must now be taken to include not only the independently variable components (actual or possible) of all parts of the given mass as initially existing, but also the components of all the new parts.

1904 A. Findlay Phase Rule ii. 12 As the components of a system there are to be chosen the smallest number of independently variable constituents by means of which the composition of each phase participating in the state of equilibrium can be expressed in the form of a chemical equation.

1913 A. G. Bloxam & S. J. Lewis Bloxam's Chem. (ed. 10) 338 The Phase Rule of Willard Gibbs..is expressed in the equation P + F = C + 2,..where P is the number of phases, F the number of degrees of freedom, and C the number of components.

1948 S. Glasstone Textbk. Physical Chem. (ed. 2) vi. 475 If ammonium chloride is vaporized into a vacuum, the system consists of one component only, in spite of the dissociation of the vapor into ammonia and hydrogen chloride; the resultant composition of the gaseous phase is still represented by NH₄Cl.

1978 P. W. Atkins Physical Chem. x. 284 How many components are present in the system NaCl/water? One answer might be two, the salt and the water. Another answer might be three, the cation, the anion, and the water... The number of Na⁺ ions must equal the number of Cl⁻ ions. This is a constraint on the composition, and so the three species give rise to only two components.
