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 = Ah2 / IG IP = IG + Ah2 IP = IG - Ah2 IP = IG / Ah2 IP = Ah2 / IG IP = IG + Ah2 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 = ΣV × ΣH tanθ = √(ΣV + ΣH) tanθ = ΣV/ΣH tanθ = ΣH/ΣV tanθ = ΣV × ΣH tanθ = √(ΣV + ΣH) tanθ = ΣV/ΣH tanθ = ΣH/ΣV ANSWER DOWNLOAD EXAMIANS APP
