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.

Textbook Question

Chapter 12, Problem 30P

GO In Fig. 12-46, a 50.0 kg uniform square sign, of edge length L = 2.00 m, is hung from a horizontal rod of length d_h = 3.00 m and negligible mass. A cable is attached to the end of the rod and to a point on the wall at distance d_v = 4.00 m above the point where the rod is hinged to the wall. (a) What is the tension in the cable? What are the (b) magnitude and (c) direction (left or right) of the horizontal component of the force on the rod from the wall, and the (d) magnitude and (e) direction (up or down) of the vertical component of this force?

A uniform rod is attached to a wall by a hinge at its base. The rod has a mass of 5.0 kg, a length of 1.8 m, is at an angle of 37° above the horizontal, and is held in place by a horizontal cord attached to the other end of the rod and bolted to the wall above the base of the rod. (a) Determine the tension in the cord. (b) Determine the horizontal and vertical components of the force exerted on the rod by the hinge. FH = ? FV = ?

A uniform rod is attached to a wall by a hinge at its base. The rod has a mass of 7.5 kg, a length of 2.3 m, is at an angle of 29° above the horizontal, and is held in place by a horizontal cord attached to the other end of the rod and bolted to the wall above the base of the rod. (a) Determine the tension in the cord. 63.715 X Where is a convenient point about which to take the torques? See if you can write an expression for the torque in terms of the force producing the torque and the perpendicular distance from the line of action of the force to the point about which we have specified to determine the torque. See if you can write a second condition of equilibrium that will allow you to determine the tension in the cord. N (b) Determine the horizontal and vertical components of the force exerted on the rod by the hinge. 36.788 X FH = Now that you know the tension in the cord from part (a), see if you can write a first condition of equilibrium statement that will allow you to…

Questions 15-19 A rod of length L with non-uniform mass distribution is hinged horizontally to a vertical wall from one end. The rod is supported by a rope from the other end as shown in the figure such that the rope makes an angle of 30° with the horizontal. The linear mass density (mass per unit of length) of the rod is A(x)=8Cx/L where x is the distance from the hinge (x < L) and C is a constant. The unit of C is kg. The distance between point mass m and the hinge is L/2. M 15. What is mass M of the rode? (а) 8C/3 (Ь) 2C (е) С/2 (а) С (е) 2C/3
