Engineering Mechanics According to Newton's first law of motion, 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 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 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
