Answer:

steradian

The SI unit of solid angle is the steradian (sr). The solid angle of a complete sphere is 4π sr. The solid angle corresponding to the face of a cube measured at the centre is 2π/3 sr.

If two forces acting at a point are represented in magnitude and direction by the two adjacent sides of a triangle taken in order, then the closing side of the triangle taken in the reversed order represents the resultant of the forces in magnitude and direction
