Engineering Mechanics The three forces of 100 N, 200 N and 300 N have their lines of action parallel to each other but act in the opposite directions. These forces are known as Coplanar non-concurrent forces Like parallel forces Coplanar concurrent forces Unlike parallel forces Coplanar non-concurrent forces Like parallel forces Coplanar concurrent forces Unlike parallel forces ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics According to the law of moments, if a number of coplanar forces acting on a particle are in equilibrium, then The algebraic sum of their moments about any point is equal to the moment of their resultant force about the same point The algebraic sum of their moments about any point in their plane is zero Their algebraic sum is zero Their lines of action are at equal distances The algebraic sum of their moments about any point is equal to the moment of their resultant force about the same point The algebraic sum of their moments about any point in their plane is zero Their algebraic sum is zero Their lines of action are at equal distances ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics The forces, which meet at one point, but their lines of action do not lie in a plane, are called Coplanar non-concurrent forces Intersecting forces Non-coplanar non-concurrent forces Non-coplanar concurrent forces Coplanar non-concurrent forces Intersecting forces Non-coplanar non-concurrent forces Non-coplanar concurrent forces ANSWER DOWNLOAD EXAMIANS APP
