Engineering Mechanics In order to determine the effects of a force, acting on a body, we must know Nature of the force i.e. whether the force is push or pull All of these Line of action of the force Magnitude of the force Nature of the force i.e. whether the force is push or pull All of these Line of action of the force Magnitude of the force 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
Engineering Mechanics According to Newton's first law of motion, The rate of change of momentum is directly proportional to the impressed force, and takes place in the same direction, in which the force acts None of these To every action, there is always an equal and opposite reaction Everybody continues in its state of rest or of uniform motion, in a straight line, unless it is acted upon by some external force The rate of change of momentum is directly proportional to the impressed force, and takes place in the same direction, in which the force acts None of these To every action, there is always an equal and opposite reaction Everybody continues in its state of rest or of uniform motion, in a straight line, unless it is acted upon by some external force ANSWER DOWNLOAD EXAMIANS APP
