“Two forces acting on a particle may be replaced by a single force called resultant which can be obtained by drawing diagonal of parallelogram, which has the sides equal to the given forces”. This statement is known as .

B. Principle of Transmissibility

“The condition of equilibrium or motion of a rigid body remains unchanged if a force acting at a given point of the rigid body is replaced by a force of same magnitude and direction, but acting at a different point provided that the two forces have the same line of action”. This statement is known as .

B. Principle of Transmissibility

“If two forces acting simultaneously on a particle can be represented by the two sides of a triangle taken in order that the third side represents the resultant in the opposite order”. This statement is known as .

A. Principle of Transmissibility

“If a number of concurrent forces acting simultaneously on a particle, are represented in magnitude and direction by the sides of polygon taken in order, then the resultant of this system of forces is represented by the closing side of the polygon in the opposite in the opposite order”. This statement is known as .

A. Principle of Transmissibility

Which of the following statements about friction is FALSE?

The total frictional force is dependent on the area of contact between the two surfaces.

The direction of frictional force on a surface is such as to oppose the tendency of one surface to slide relative to the other.

The magnitude of the frictional force is equal to the force which tends to move the body till the limiting value is reached.

Friction force is always less than the force required to prevent motion.

In the analysis of friction, the angle between the normal force and the resultant force the angle of friction.

may be greater than or less than

area and square of the distance between two parallel axes

area and distance between two parallel axes

square of the area and distance between two parallel axes

square of the area and square of the distance between two parallel axes

The number of independent degrees of freedom is:

Total degrees of freedom – number of constrain equations

Square root of the square of the difference of total degrees of freedom – number of constrain equations

Square root of the total degrees of freedom – number of constrain equations

Total degrees of freedom – half the number of constrain equations
