Engineering Mechanics Two like parallel forces are acting at a distance of 24 mm apart and their resultant is 20 N. It the line of action of the resultant is 6 mm from any given force, the two forces are 15 N and 15 N 15 N and 5 N 20 N and 5 N None of these 15 N and 15 N 15 N and 5 N 20 N and 5 N None of these ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics The total momentum of a system of masses (i. e. moving bodies) in any one direction remains constant, unless acted upon by an external force in that direction. This statement is called Principle of conservation of momentum Newton's first law of motion Newton's second law of motion Principle of conservation of energy Principle of conservation of momentum Newton's first law of motion Newton's second law of motion Principle of conservation of energy ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics The maximum frictional force, which comes into play, when a body just begins to slide over the surface of the other body, is known as Dynamic friction Coefficient of friction Static friction Limiting friction Dynamic friction Coefficient of friction Static friction Limiting friction ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics In order to determine the effects of a force, acting on a body, we must know All of these Magnitude of the force Line of action of the force Nature of the force i.e. whether the force is push or pull All of these Magnitude of the force Line of action of the force Nature of the force i.e. whether the force is push or pull ANSWER DOWNLOAD EXAMIANS APP
