A uniform steel girder AB is 6.0 mlong and has a mass equivalent to 4.0 kNacting at its centre. The girder rests on two supports at Cand Bas shown in figure 2. A point load of 20.0 kNis attached to the beam as shown. Prove that the value of the forceFwould causethe beam to just lift off the support B.
Rotational Equilibrium And Rotational Dynamics
In physics, the state of balance between the forces and the dynamics of motion is called the equilibrium state. The balance between various forces acting on a system in a rotational motion is called rotational equilibrium or rotational dynamics.
Equilibrium of Forces
The tension created on one body during push or pull is known as force.

b.Friction is indispensable in the affairs of human being.Explain briefly giving examples and applications why the above assertionis true?If you think it is false, explain and give examples.
c.Force is a vector quantity and thus has both a magnitude and a direction. A vector can be represented graphically by a line drawn to scale in the direction of the line of action of the force. To distinguish between vector and scalar quantities, various ways are used. Identify and explain threeof these ways.
