Three forces are at translational equilibrium. Which statement(s) below are true?
I. The vector of the sum of the 3 Forces = 0.
II. The magnitude of the 3 Forces must be equivalent.
III. The 3 Forces must be parallel.
Homework Answers
When three forces are at translational equilibrium, It means that the vector sum of the 3 force is zero.
Correct option is I.
F1 + F2 + F3 = 0
Here |F1|, |F2|, & |F3| can be anything, but it will be like this that there sum will be zero.
for ex. F1 + F2 = -F3, etc.
Also It's not necessary for them to be parallel. Since sum of three parallel forces cannot be zero.
