Strength of Materials The magnitude of two forces, which when acting at right angle produce resultant force of VlOkg and when acting at 60° produce resultant of Vl3 kg. These forces are 3 and 1 kg V5 and V5 2 and 5 2 and V6 3 and 1 kg V5 and V5 2 and 5 2 and V6 ANSWER DOWNLOAD EXAMIANS APP
Strength of Materials The product of either force of couple with the arm of the couple is called resultant couple moment of the couple resulting couple moment of the forces resultant couple moment of the couple resulting couple moment of the forces ANSWER DOWNLOAD EXAMIANS APP
Strength of Materials According to principle of moments positive and negative couples can be balanced if a system of coplanar forces is in equilibrium, then their algebraic sum is zero the algebraic sum of the moments of any two forces about any point is equal to moment of theiwesultant about the same point if a system of coplanar forces is in equilibrium, then the algebraic sum of their moments about any point in their plane is zero positive and negative couples can be balanced if a system of coplanar forces is in equilibrium, then their algebraic sum is zero the algebraic sum of the moments of any two forces about any point is equal to moment of theiwesultant about the same point if a system of coplanar forces is in equilibrium, then the algebraic sum of their moments about any point in their plane is zero ANSWER DOWNLOAD EXAMIANS APP
