Engineering Mechanics According to Newton's first law of motion, 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 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 ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics According to parallel axis theorem, the moment of inertia of a section about an axis parallel to the axis through center of gravity (i.e. IP) is given by(where, A = Area of the section, IG = Moment of inertia of the section about an axis passing through its C.G., and h = Distance between C.G. and the parallel axis.) IP = IG + Ah2 IP = IG / Ah2 IP = IG - Ah2 IP = Ah2 / IG IP = IG + Ah2 IP = IG / Ah2 IP = IG - Ah2 IP = Ah2 / IG ANSWER DOWNLOAD EXAMIANS APP
