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.
Question
![**Chapter 12, Problem 034**
In the figure, a thin horizontal bar \( AB \) of negligible weight and length \( L = 3.1 \, \text{m} \) is hinged to a vertical wall at \( A \) and supported at \( B \) by a thin wire \( BC \) that makes an angle \( \theta = 42^\circ \) with the horizontal. A block of weight \( W = 250 \, \text{N} \) can be moved anywhere along the bar; its position is defined by the distance \( x = 1.75 \, \text{m} \) from the wall to its center of mass. Find (a) the tension in the wire, and the (b) horizontal and (c) vertical components of the force on the bar from the hinge at \( A \).
---
**Diagram Explanation**:
The diagram shows:
- A vertical wall with point \( A \) where the bar \( AB \) is hinged.
- The bar \( AB \) extends horizontally from the wall.
- A block of weight \( W = 250 \, \text{N} \) is placed at a distance \( x = 1.75 \, \text{m} \) from the wall on the bar.
- A wire \( BC \) supports the end of the bar at \( B \), making an angle \( \theta = 42^\circ \) with the horizontal.
- The length of the bar \( L = 3.1 \, \text{m} \).
**Input Fields**:
- (a) Number [Units]
- (b) Number [Units]
- (c) Number [Units]
