SUMMARY
Calculating static equilibrium requires understanding the relationship between angles and their respective components. When using the SOH-CAH-TOA mnemonic, the sine function is applied to the component opposite the angle, while the cosine function is used for the adjacent component. This relationship is contingent upon whether the angle is measured from the x-axis or y-axis. If the angle is relative to the y-axis, the sine function applies to the x-component, necessitating careful attention to the reference axis when resolving forces.
