I've got to work on my report on Gravesand's apparatus which requires parallelogram method to find the resultant force and this vid really helps me out. Online classes are so tedius, Thanks a lot .

Draw a scale diagram, and measure the diagonal using a ruler, and convert it to the force unit using the scale eg 1cm:2N

what is the existence of(2) in ( 2abcos135)? is it because we have 2 forces or is there some point behind it? please if you could explain why the law is like that?
@MathandStatsHelp4 жыл бұрын
It has to do with the derivation of the Law of Cosines. The Pythagorean Theorem, a^2+b^2=c^2, only applies to right triangles. The Law of Cosines applies to all triangles and is derived using two right triangles within the given non-right triangle. You can Google derivation of Law of Cosines to see how it is derived. It's very hard to type out the process in a reply.

I don't understand how the angle c is 180-45? Please help with this.
@MathandStatsHelp3 жыл бұрын
Since the opposite sides of parallelograms are parallel, the rules for parallel lines apply. The two angles are same side interior angles and they are always supplementary. Supplementary means they have a sum of 180°.

To get the angle of c, why 180°?

Since it forms a parallelogram, the consecutive interior angles (angles next to each other) are supplementary.

@MathandStatsHelp5 жыл бұрын
It's not drawn to scale. Sometimes you have things that can't be measured directly, which is why we use Law of Sines and Cosines to help with measuring things indirectly.
