1- the forces must act parallel to each other not at the same line of action
2- if they form an angle then you must make resoltution and take the force which is prependicular to theline joining between the point of action
true
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.
Not necessarily. The Tropic of Cancer, and the Tropic of Capricorn, imaginary lines on the surface of the earth (an approximate sphere), are parallel but they are not coplanar. You could draw similar lnes on a proper sphere that were parallel but not coplanar.
false
They are ALWAYS coplanar! This is because the definition says so! You have to read it first, in order to get the answer!
Coplanar or not, the two conditions for equilibrium are:The sum of all forces must be zeroThe sum of all torques must be zero.
are two lines that are not parallel, coplanar, and do not intersect
Parallel lines in Euclidean space are always coplanar.
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
Parallel forces are forces acting in parallel lines. If two parallel forces act in same direction, they are called like parallel forces. If two parallel forces act in opposite directions, they are called unlike parallel forces.
parallel
In general, no.
Parallel.
Coplanar lines that do not intersect are called parallel lines.
Parallel lines will be co-planar.
Coplanar lines that do not intersect (have no common point) are parallel.Two objects are coplanar if they both lie in the same plane, they must either intersect or be parallel.
