Question #201f0

Answer 1

Ti Is the vector sum of all the forces applied at the same point.
Every time a system is in equilibrium, `R=0`.

Explanation:

Being `R` the resultant and `F_i` one of the `N` Forces applied at a point `O` we have:

`ul(R)= sum_(i=1)^N ulF_i`

Examples:
- the tug of war when neither of the two sides are winning
