4) Forces are called concurrent when their lines of action meet in
- one point
- two points
- plane
- perpendicular planes
- different planes

- perpendicular planes
- different points
Show Answer
Answer = one plane
6) A force acting on a body may
- introduce internal stresses
- balance the other forces acting on it
- retard its motion
- change its motion
- all of the above
Show Answer
Answer = all of the above
7) A number of forces acting at a point will be in equilibrium if
- their total sum is zero
- two resolved parts in two directions at right angles are equal
- sum of resolved parts in any two per-pendicular directions are both zero
- all of them are inclined equally
- none of the above
Show Answer
Answer = sum of resolved parts in any two per-pendicular directions are both zero
8) Two non-collinear parallel equal forces acting in opposite direction
- balance each other
- constitute a moment
- constitute a couple
- constitute a moment of couple
- constitute a resultant couple
Show Answer
Answer = constitute a couple
9) According to principle of moments
- if a system of coplanar forces is in equilibrium, then their algebraic sum is zero
- if a system of coplanar forces is in equilibrium, then the algebraic sum of their moments about any point in their plane is zero
- the algebraic sum of the moments of any two forces about any point is equal to moment of theiwesultant about the same point
- positive and negative couples can be balanced
- none of the above
Show Answer
Answer = if a system of coplanar forces is in equilibrium, then the algebraic sum of their moments about any point in their plane is zero
