The forces which meet at one point and have their line of action in different planes are called
Non-coplanar concurrent forces
Combining these two characteristics, the forces are non-coplanar concurrent forces . Therefore, the forces which meet at one point and have their line of action in different planes are called non-coplanar concurrent forces. The equilibrium conditions for a system of non-coplanar concurrent forces are that the vector sum of all forces is zero.
Important Questions from Equilibrium and Friction
If in a planar system, only 2 reaction forces are acting, then the system is:-
By applying the static equations i.e. ∑H = 0, ∑V = 0 and ∑M = 0. To a determine structure, we may determine:
Which of the following is not a type of equilibrium?
Varingon’s theorem of moments states that if a number of coplanar forces acting on a particle are in equilibrium, then
A block of mass 4√2 kg is at rest on the inclined plane. The inclined plane is inclined at an angle of 135° from horizontal direction in anticlockwise direction. Determine the coefficient of friction so that block can start slide in downward direction, assume the acceleration of gravity as 10 m/s2.
