No. It all depends on what angle you are using. If the angle is with respect to the x-axis, then fine: The x-component would use cosine, etc. But if the given angle is with respect to the y-axis, things are reversed.Mason98 said:

Static equilibrium refers to a state in which all forces acting on an object are balanced, resulting in no net acceleration or movement of the object.
SOH/CAH/TOA are trigonometric ratios that are commonly used in calculating forces and angles in static equilibrium problems. They provide a way to relate the forces and angles in a right triangle, making it easier to solve for unknown values.
First, identify the forces acting on the object and draw a free body diagram. Then, use the appropriate trigonometric ratio (SOH/CAH/TOA) to solve for the unknown force or angle. Repeat this process for each unknown value until all forces and angles are known and the object is in a state of static equilibrium.
One common mistake is using the wrong trigonometric ratio for the given problem. It is important to carefully identify the sides and angles in the right triangle and use the corresponding ratio. Another mistake is not properly considering the direction of the forces, which can result in incorrect calculations.
No, SOH/CAH/TOA are only applicable to right triangles. In non-right triangles, other trigonometric functions such as sine, cosine, and tangent must be used to calculate forces and angles in static equilibrium.
