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 = ΣH/ΣV tanθ = ΣV/ΣH tanθ = ΣV × ΣH tanθ = √(ΣV + ΣH) tanθ = ΣH/ΣV tanθ = ΣV/ΣH ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics Varingon's theorem of moments states that if a number of coplanar forces acting on a particle are in equilibrium, then 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 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 ANSWER DOWNLOAD EXAMIANS APP
