Parallelogram method is used to determine the components of vector along the axes, into x axis

and y axis. This is to find the magnitude of horizontal component which is at x axis and magnitude
of vertical component is at y axis.

Example 2.1

Resolve the 30 N forces into components along the u and v axes as shown in Figure 2.11 (a).

Calculation
Given data

R = 30 N
U = __

V = __

Use law of cosines and law sines because only one sides and angles are known.
