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 is equal to the moment of their resultant force about the same point Their lines of action are at equal distances The algebraic sum of their moments about any point in their plane is zero 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 Their lines of action are at equal distances The algebraic sum of their moments about any point in their plane is zero Their algebraic sum is zero ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics In a screw jack, the effort required to lift the load is given by (where W = Load lifted, α = Helix angle, and φ = Angle of friction.) P = W tan (α - φ) P = W tan (φ - α) P = W tan (α + φ) P = W cos (α + φ) P = W tan (α - φ) P = W tan (φ - α) P = W tan (α + φ) P = W cos (α + φ) ANSWER DOWNLOAD EXAMIANS APP
