Magnitude and direction question

In summary, a question is asked about determining the forces exerted on a sign supported by a chain and bracket. The horizontal rod cannot support vertical forces. The individual asking for help expresses dislike for learning from the book and asks for guidance in solving the problem, specifically whether to use the law of Sins or Cos.

"A sign weighting 495N is supported as shown in the attachment. Determine the magnitudes and directions of the forces exerted by the chain and by the bracket. assume that the horizontal rod cannot support vertical forces."


How do I set up this question? Do I use the law of Sins? Cos?

I really hate learning from the book, and since the book didn't show an example of this type of problem I don't really know where to start. Not asking for the solution, just a little kick start help. Thanks

cant see the jpg but if the angle is mentoined then you could use sins and cosines and then do the rest...

FAQ: Magnitude and direction question

What is magnitude?

Magnitude refers to the size or quantity of something, such as the strength or intensity of a force or the size of a vector in mathematics.

How is magnitude measured?

The unit of measurement for magnitude depends on the specific quantity being measured. For example, magnitude of force is measured in newtons, while magnitude of velocity is measured in meters per second.

What is direction?

Direction refers to the orientation or angle of an object or vector in relation to a reference point or axis. It can be described using compass directions (north, south, east, west) or degrees.

How is direction represented?

Direction can be represented using a variety of methods, such as arrows, compass directions, or angles. In mathematics, direction is often represented using unit vectors, which have a magnitude of 1 and point in a specific direction.

Why is it important to consider both magnitude and direction?

In many scientific and mathematical calculations, both magnitude and direction are crucial for accurate results. For example, in physics, the force applied to an object (magnitude) and the direction of that force can determine the motion of the object. In mathematics, the magnitude and direction of a vector can determine its endpoint on a graph.
