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 concurrent forces Coplanar non-concurrent forces Like parallel forces Unlike parallel forces Coplanar concurrent forces Coplanar non-concurrent forces Like parallel forces Unlike parallel forces ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics A spherical body is symmetrical about its perpendicular axis. According to Routh's rule, the moment of inertia of a body about an axis passing through its centre of gravity is (where, M = Mass of the body, and S = Sum of the squares of the two semi-axes.)
