ENGINEERING MECHANICS

Each body remains in its state of rest or motion uniform in direction until it is made to

change this state by imposed forces.

• newtons first law

• newtons second law

• newtons third law

• parallelogram law

which law states that the rate of change of momentum of a body is directly proportional to the force applied, and this change in momentum takes place in the direction of the applied force.

• Newtons first law

• Newtons second law

• Newtons third law

• Lami's theorem

which law states that all forces between two objects exist in equal magnitude and opposite direction

• Newtons First Law

• Newtons Second Law

• Newtons Third Law

• Lami"s Theorem

Two vectors acting simultaneously at a point and represented both in magnitude and direction by two adjacent sides OA and OD of a parallelogram then the resultant force act in the diagonal of the parallelogram is called

• Parallelogram Law

• Triangular law

• Newtons law

• none of the above

Which law states that when two vectors are represented as two sides of the triangle with the order of magnitude and direction, then the third side of the triangle represents the magnitude and direction of the resultant vector.

• triangular Law

• parallelogram Law

• Varignons theorem

• Newtons Law

If force acting at one pint is called

• co planar force

• concurrent force

• non concurrent force

• non co-planar

If the force act in same plane is called

• co planar force

• non co planar force

• concurrent force

• non concurrent force

If two force acting in opposite direction in the same line of action is called

• like forces

• unlike force

• unlike co linear forces

• co-linear force

If two forces acting on the same line of action but in different plane is called

• non coplanar non concurrent force

• non coplanar concurrent force

• colinear force

• non colinear force

Which law states that if three forces acting at a point are in equilibrium, each force is proportional to the sine of the angle between the other two forces

• parallelogram Law

• triangular Law

• Lami's Theorem

• NONE OF THE ABOVE
