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 11, Problem 34PCE

A stick with a mass of 0.214 kg and a length of 0.436 m rests in contact with a bowling ball and a rough floor, as shown in Figure 11-48. The bowling ball has a diameter of 21.6 cm, and the angle the stick makes with the horizontal is 30.0°. You may assume there is no friction between the stick and the bowling ball, though friction with the floor must be taken into account. (a) Find the magnitude of the force exerted on the stick by the bowling ball. (b) Find the horizontal component of the force exerted on the stick by the floor. (c) Repeat part (b) for the vertical component of the force.

As shown in the figure below, a stick of length L = 0.435 m and mass m = 0.300 kg is in contact with a rough floor at one end and a frictionless bowling ball (diameter d = 15.00 cm) at some other point such that the angle between the stick and the floor is e = 30°. Determine the following. 30.0° (a) magnitude of the force exerted on the stick by the bowling ball 1.49 Since the stick is in static equilibrium, we expect to use the first and second condition of equilibrium. Since we need to determine torques, before starting the problem, see if you can write an expression for the torque in terms of the force producing the torque and the perpendicular distance between the line of action of this force and the point about which we are determining the torques. Determine a convenient point about which to determine the torques. It will be to your advantage to draw a careful figure which includes the stick, all dimensions and angles, all forces acting on the stick, the point about which you plan…

A 10 N ball is supported by an incline and a cable making an angle a with the vertical direction. Knowing the force in the cable equal to 5 N, determine the angle a and the force exerted by the ball on the incline. Consider the ball as a particle.

A 2×12 board is about 2.18 kg per linear foot. A 16-foot length board of Southern Yellow Pine is placed against a wall such that the angle between the wall and the length of the board is 20°. Assume that the wall is perfectly smooth (a.k.a. the coefficient of friction between the wall and the board is zero). (a) What is the normal force between the wall and the board? (b) What is the normal force between the board and the floor? (c) What is the force of static friction between the board and the floor? (d) What is the coefficient of static friction between the board and the floor?
