The maximum value of the frictional force that can be applied to the composite body under which the theorem of the Pappus and Guldinus is going to be applied is called _________
Detailed Solution for Test: Theorem Of Pappus And Guldinus - Question 8

The friction is the phenomena that defines that there is a resistance which is present there between the two surfaces. The two surfaces are in contact and the friction applies at that surface only, resisting the motion of the surface. Thus the maximum values is called as limiting friction.

When the body which is applied forces come in the stage of the limiting friction then the body over which this theorem is to be applied is termed as to come in ___________ equilibrium.
Detailed Solution for Test: Theorem Of Pappus And Guldinus - Question 10

As the limiting friction is the maximum value of the frictional forces. Thus if more force is applied to the body then the body is going to move forward. Because the two surfaces are in contact and the friction applies at that surface only, resisting the motion of the surface. Thus the name unstable equilibrium.

We use sometimes the measures to know the direction of moment. It is done by right handed coordinate system. Which is right about it for the bodies over which this theorem is going to be applied (consider the mentioned axis to be positive)?
Detailed Solution for Test: Theorem Of Pappus And Guldinus - Question 11

As right handed coordinate system means that you are curling your fingers from positive x-axis towards y-axis and the thumb which is projected is pointed to the positive z-axis. Thus visualizing the same and knowing the basic members of axis will not create much problem.

What is not the condition for the equilibrium in three dimensional system of axis for the bodies for which this theorem is going to be applied?
Detailed Solution for Test: Theorem Of Pappus And Guldinus - Question 12

For the equilibrium in the three dimensional system of axis we have all the conditions true as, ∑Fx=0, ∑Fy=0 and ∑Fz=0. Also we have the summation of the forces equal to zero. Which is not a non-zero value.

What is a collinear system of forces for the bodies over which this theorem is to apply?
Detailed Solution for Test: Theorem Of Pappus And Guldinus - Question 13

The force system having all the forces emerging from a point is called the collinear system of force. This is a type of system of the force, which is easy in the simplification. This is because as the forces are the vector quantity, the vector math is applied and the simplification is done.

The system of the collinear and the parallel force for the bodies over which this theorem is to be applied are simplified as:
Detailed Solution for Test: Theorem Of Pappus And Guldinus - Question 14

The simplification is easy. The simplified force system gives us a net force and the parallel force system gives us a simplified force, and then we add it vectorially. Thus the vector addition at the last can be easily done and thus both can be simplified.

If solving the question in 3D calculations is difficult, then use the 2D system to make the use of the theorem.
Detailed Solution for Test: Theorem Of Pappus And Guldinus - Question 15

The answer is obviously yes. If we are having any difficulty in making the vector components, then we can go in 2D. As if the particle is in equilibrium, the net force will be zero. No matter where you see first. Net force is zero.
