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 = Ah2 / IG IP = IG + Ah2 IP = IG / Ah2 IP = IG - Ah2 IP = Ah2 / IG IP = IG + Ah2 IP = IG / Ah2 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 Newton's first law of motion Newton's second law of motion Principle of conservation of momentum Principle of conservation of energy Newton's first law of motion Newton's second law of motion Principle of conservation of momentum Principle of conservation of energy ANSWER DOWNLOAD EXAMIANS APP
