What is the necessary condition for equilibrium of system of coplanar forces?
Coplanar or not, the two conditions for equilibrium are:The sum of all forces must be zeroThe sum of all torques must be zero.
What do you mean by coplanner system of intersecting forces?
These are forces which act in the same plane (coplanar, not coplanner!) and that their lines of action all meet at a single point.
Are the collinear vectors and parallel vectors the same?
Collinear forces are concurrent system type of forces, whereas parallel vector forces cannot be concurrent system type of force but they can be coplanar nonconcurrent system type of force
Statement of polygon law of forces?
if several COPLANAR FORCES are acting at a point simultaneously such that each one of them can be represented in direction and magnitude by a side of a polygon, taken in order, then the resultant is given by the closing side in the reverse order
How many non co planer vectors gives resultant zero?
If they are not coplanar, you would need at least four forces to get a net force (resultant force) of zero.
