Engineering Mechanics According to Newton's first law of motion, Everybody continues in its state of rest or of uniform motion, in a straight line, unless it is acted upon by some external force To every action, there is always an equal and opposite reaction None of these 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 Everybody continues in its state of rest or of uniform motion, in a straight line, unless it is acted upon by some external force To every action, there is always an equal and opposite reaction None of these 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 ANSWER DOWNLOAD EXAMIANS APP
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 Unlike parallel forces Coplanar non-concurrent forces Like parallel forces Coplanar concurrent forces Unlike parallel forces Coplanar non-concurrent forces ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics The principle of transmissibility of forces states that, when a force acts upon a body, its effect is Same at every point on its line of action Minimum, if it acts at the center of gravity of the body Maximum, if it acts at the center of gravity of the body Different at different points on its line of action Same at every point on its line of action Minimum, if it acts at the center of gravity of the body Maximum, if it acts at the center of gravity of the body Different at different points on its line of action ANSWER DOWNLOAD EXAMIANS APP
