Engineering Mechanics Varingon's theorem of moments states that if a number of coplanar forces acting on a particle are in equilibrium, then Their lines of action are at equal distances Their algebraic sum is zero The algebraic sum of their moments about any point is equal to the moment of their resultant force about the same point The algebraic sum of their moments about any point in their plane is zero Their lines of action are at equal distances Their algebraic sum is zero The algebraic sum of their moments about any point is equal to the moment of their resultant force about the same point The algebraic sum of their moments about any point in their plane is zero 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 = g cos β/2u sin (α - β) t = g cos β/2u sin (α + β) t = 2u sin (α + β)/g cos β t = 2u sin (α - β)/g cos β t = g cos β/2u sin (α - β) t = g cos β/2u sin (α + β) t = 2u sin (α + β)/g cos β t = 2u sin (α - β)/g cos β ANSWER DOWNLOAD EXAMIANS APP
