What is the necessary condition for equilibrium of system of coplanar forces?
ManishRajRanjan
Coplanar or not, the two conditions for equilibrium are:
- The sum of all forces must be zero
- The sum of all torques must be zero.

What is lemis theorem?
from ramanjit singhIts Lamis Theorom.In statics, Lamis theorem is an equation relating the magnitudes of three coplanar, concurrent and non-collinearforces, which keeps an object in static equilibrium, with the angles directly opposite to the corresponding forces. According to the theorem,where A, B and C are the magnitudes of three coplanar, concurrent and non-collinear forces, which keep the object in static equilibrium, andα, β and γare the angles directly opposite to the forces A, Band C respectively.Do you like the answer?

Finding a problem and solutions to coplanar and non coplanar forces?
ABCD is a squre. forces of magnitudes 1,2,3,P, and Q units act along AB, BC, CD, DA and AC respectively. find the value of P and Q so that the resultant of five forces is a couple
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
What are equilibrium of coplanar forces?
equilbrium in coplaner forces at rigid body.
What is the condition of coplanar forces in equilibrium?
In equilibrium, coplanar forces must satisfy two conditions: first, the vector sum of all forces in any direction must be zero (ΣF = 0); second, the vector sum of all moments (torques) about any point must be zero (Στ = 0). These conditions ensure that the forces are balanced and there is no rotational motion.
What condition can cause a rigid body remain in equilibrium when acted upon by a non parallel coplanar force?
A rigid body will remain in equilibrium when acted upon by a non-parallel coplanar force if the vector sum of all forces acting on the body is zero, and the vector sum of all torques (or moments) acting on the body is also zero. This condition is known as the equilibrium of forces and moments.
Explain the two conditions of equilibrium?
first condition for equilibrium is that the a body is satisfy with first condition if the resultant of all the forces acting on it is zero let n numbers of the forces F1, F2,F3,.........., Fn are acting on a body such that sigmaF=0 a book lying on a table or picture hanging on the wall are at rest and thus satisfy with first condition of equilibrium a paratrooper coming with terminal velocity also satisfies first condition of equilibrium
What is the definition of coplanar and non coplanar forces?
Coplanar forces are a set of forces all of which act in the same plane. Non-coplanar forces are a set of forces in which at least one act in a direction incline to the plane formed by two of the forces.
What are related words for balanced forces?
Equilibrium, stability, static forces.
What is the condition that must exist in order for a body to attain equilibrium?
The equilibrium condition requires the sum of the forces on the body to be zero.
Why should three forces which are in equilibrium be coplaner and concurrent?
If suppose they are not coplanar then resultant of any two cannot cancel the third one and so equilibrium cannot be maintained. Same way as the forces are not concurrent then the same balancing of the resultant by the third one will not be possible.
What is coplanar forces?
Coplanar just means that all forces act within a single plane, rather than in three dimensions. Examples aren't really necessary -- it's really a mathematical abstraction, because in the real world forces act in three dimensions.
What is internal equilibrium?
The internal equilibrium is a balance condition between internal forces and the commulative integrated stresses.
Difference between concurrent coplanar forces and non concurrent coplanar forces?
Concurrent coplanar forces have their lines of action intersecting at a common point, allowing them to be resolved using the parallelogram law of forces. Non-concurrent coplanar forces have their lines of action not intersecting at a common point, requiring the use of the triangle law of forces for resolution.
First condition of equilibrium?
The first condition of equilibrium states that the net force acting on an object must be zero for the object to remain at rest or move at a constant velocity. This condition is also known as the vector sum of all forces being equal to zero.
