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.

Chapter 12, Problem 28P

GO In Fig. 12-45, suppose the length L of the uniform bar is 3.00 m and its weight is 200 N. Also, let the block’s weight W = 300 N and the angle θ = 30.0°. The wire can withstand a maximum tension of 500 N. (a) What is the maximum possible distance x before the wire breaks? With the block placed at this maximum x, what are the (b) horizontal and (c) vertical components of the force on the bar from the hinge at A?

A rectangular current loop (a = 15.0 cm, b = 34.0 cm) is located a distance d = 10.0 cm near a long, straight wire that carries a current (Iw) of 17.0 A (see the drawing). The current in the loop is IL = 21.0 A. Determine the magnitude of the net magnetic force that acts on the loop. Solve in N. a b IL Iw

Two long, straight wires are separated by distance, d = 22.0 cm. The wires carry currents of I1 = 7.50 A and I2 = 5.50 A in opposite directions, as shown in the figure. Find the magnitude of the net magnetic field at point (B). Let r₁ = 12.0 cm, r2 = 7.00 cm, and r3 = 13.0 cm. Solve in T. 12 d A √3
