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 Everybody continues in its state of rest or of uniform motion, in a straight line, unless it is acted upon by some external force None of these To every action, there is always an equal and opposite reaction 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 None of these To every action, there is always an equal and opposite reaction ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics If the resultant of two equal forces has the same magnitude as either of the forces, then the angle between the two forces is 60° 120° 90° 30° 60° 120° 90° 30° ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics If a number of forces are acting at a point, their resultant will be inclined at an angle 'θ' with the horizontal, such that tanθ = ΣH/ΣV tanθ = √(ΣV + ΣH) tanθ = ΣV × ΣH tanθ = ΣV/ΣH tanθ = ΣH/ΣV tanθ = √(ΣV + ΣH) tanθ = ΣV × ΣH tanθ = ΣV/ΣH ANSWER DOWNLOAD EXAMIANS APP
