The force f of magnitude 100 lb is to be resolved into two components along the lines a-a and b-b. determine by trigonometry the angle a, knowing that the component of f along line a-a is 40 lb\

θ=66.42°

Explanation:

Given that

F= 100 lb

The force along a-a is 40 lb

Lets take θ is the angle made by force F from a-a

So the component of force F along a-a will F cosθ and the component of force along b-b is F sinθ.

The force along a-a given that 40 lb,so we can say that

  F cosθ= 40

  100  cosθ = 40

cosθ= 0.4

θ=66.42°

The angle from a-a is 66.42°.

i don’t know what the answer is i wish i

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
