Strength of Materials According to principle of moments 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 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 ANSWER DOWNLOAD EXAMIANS APP
Strength of Materials A semi-circular disc rests on a horizontal surface with its top flat surface horizontal and circular portion touching down. The coefficient of friction between semi-cricular disc and horizontal surface is i. This disc is to be pulled by a horizontal force applied at one edge and it always remains horizontal. When the disc is about to start moving, its top horizontal force will unpredictable slant up towards direction of pull slant down towards direction of pull remain horizontal unpredictable slant up towards direction of pull slant down towards direction of pull remain horizontal ANSWER DOWNLOAD EXAMIANS APP
Strength of Materials Coefficient of friction is the the friction force acting when the body is just about to move ratio of limiting friction and normal reaction angle between normal reaction and the resultant of normal reaction and the limiting friction the friction force acting when the body is in motion the friction force acting when the body is just about to move ratio of limiting friction and normal reaction angle between normal reaction and the resultant of normal reaction and the limiting friction the friction force acting when the body is in motion ANSWER DOWNLOAD EXAMIANS APP
