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 Like parallel forces Coplanar concurrent forces Coplanar non-concurrent forces Unlike parallel forces Like parallel forces Coplanar concurrent forces Coplanar non-concurrent forces Unlike parallel forces ANSWER DOWNLOAD EXAMIANS APP
