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 The time of flight (t) of a projectile on an upward inclined plane is(where u = Velocity of projection, α = Angle of projection, and β = Inclination of the plane with the horizontal.) t = 2u sin (α + β)/g cos β t = g cos β/2u sin (α - β) t = 2u sin (α - β)/g cos β t = g cos β/2u sin (α + β) t = 2u sin (α + β)/g cos β t = g cos β/2u sin (α - β) t = 2u sin (α - β)/g cos β t = g cos β/2u sin (α + β) ANSWER DOWNLOAD EXAMIANS APP
