Fluid Kinematics

The branch of science that deals with objects which are either in motion or stationary are studied under the branch of classical mechanics. Fluid mechanics is a subcategory of classical mechanics that deals with the behavior of fluids at rest (fluid statics) or in motion (posing some velocity). In fluid kinematics, studies focus on the associated motion of fluid particles or groups of particles, and its associated parameters like displacements, velocity, and acceleration without concerning about the forces that caused the motion. All the laws of classical mechanics are applied in the study of fluid kinematics.

### Determining the Moment of Each of the Three Forces About Points A and B

#### Problem Statement:
Determine the moment of each of the three forces about points A and B.

#### Diagram Explanation:
The diagram consists of a horizontal and vertical structure with several forces applied to it. The structure forms an L-shape with the following features:

- **Point A** is the leftmost end of the horizontal segment.
- The horizontal segment extends 2 meters from point A and then another 3 meters before turning vertically downward.
- **Point B** is the bottom of the vertical segment, which is 4 meters long.

Three forces are applied to the structure:

1. **Force F1 = 250 N** is applied at point A at a 30-degree angle to the horizontal.
2. **Force F2 = 300 N** is applied at the intersection of the horizontal and vertical segments at a 60-degree angle to the horizontal.
3. **Force F3 = 500 N** is applied at point B at a downward-right angle with direction ratios corresponding to 3 (horizontal): 4 (vertical): 5 (hypotenuse).

#### Calculation of Moments:
To calculate the moments, you need to find the perpendicular distances from each force's line of action to the points A and B.

1. **Moment of F1 about A:**
\( \text{Moment} (M) = F \times d \)

Since Force F1 passes through point A, its moment about point A is 0.

2. **Moment of F2 about A:**
- Horizontal distance of F2 from A is 5 meters (2m + 3m).
- Moment Arm = \( 5m \sin(60^\circ) \) for the vertical component of F2.
- \( M_{F2-A} = 300 N \times 5 m \times \sin(60^\circ) = 300 \times 5 \times (\sqrt{3}/2) \)

3. **Moment of F3 about A:**
- Horizontal distance from A to the vertical segment = 5 meters.
- Vertical distance from A to B = 4 meters.
- Using the right triangle ratio given, the horizontal component = 3/5 of 500N, and the vertical component = 4/5 of 500N.
- \( M_{F3-A

Select the correct statements regarding the addition of moments. (Select 3) Moments have directions, so a negative value implies it is along the opposite direction from the reference direction. All the moments need to have the same reference point/pivot in order to add together. Calculate each moment by multiplying each force with its distance to the reference point, and add all values together, regardless of their direction. You have to define the reference direction first, either clockwise or counter-clockwise.
