In summary, a stick is attached to a wall with a hinge and a string, forming a right triangle. The forces acting on the stick include tension, gravity, and a normal force from the wall. There should also be a frictional force at the stick-wall connection.

Homework Statement


A stick is connected by a hinge to a wall. The other end of the stick is attached to the wall with a string. The stick is horizontal and has length L and the string makes an angle of θ with the stick.



The Attempt at a Solution


So imagine a right triangle. The vertical side adjacent to the right angle is the wall. The horizontal adjacent side is the stick, connected to the wall. The hypotenuse is the string connecting the edge of the stick to the wall.

The forces acting on the stick would be according to me:

The tension, acting in the same direction of the string, but can be broken down into x and y components. The mg of the stick, acting on it in the middle of the stick. The normal force from the wall-stick connection acting in the horizontal direction.

I'm wondering if there would be a frictional force pointing in the up direction at the stick wall connection?

Yes there should be.
 

1. What is the purpose of identifying all forces on this stick?

The purpose of identifying all forces on this stick is to understand the various forces acting on the stick, which can help determine its motion and stability.

2. How do you identify all forces on a stick?

To identify all forces on a stick, you need to first draw a free body diagram of the stick, which includes all of the external forces acting on the stick. Then, you can use Newton's laws of motion to analyze the forces and determine their magnitude and direction.

3. What are some common forces that may act on a stick?

Some common forces that may act on a stick include gravity, normal force, friction, and applied forces (such as a person pushing or pulling on the stick).

4. How can knowing the forces on a stick be useful in real-world applications?

Knowing the forces on a stick can be useful in real-world applications such as engineering and construction. By understanding the forces acting on a structure or object, engineers can design and build stronger and more stable structures.

5. Are there any limitations to identifying all forces on a stick?

Yes, there may be limitations to identifying all forces on a stick. For example, if the stick is in a fluid or gas environment, there may be additional forces acting on it that are difficult to measure or predict. Additionally, the stick may be subject to internal forces that are not visible from the outside.
