Question

4. Three forces each of magnitude P and acting in the positive direction of the axes have
their lines of action - y = 2 = a; - 2 = x = a; - x = y = a
Prove that they are equivalent to a force P √3 at the origin and a couple.
​

Answer 1

Answer:

When three forces acting at a point are in equilibrium, then each force is numerically equal to the sum of the other two each force is numerically greater than the sum of the other two each force is numerically greater than the difference of the other two none of the above.
