### Crane Load and Moment Calculation

#### Context

The image details a mechanical problem involving a tower crane used to hoist a 2.2-Mg load upwards at a constant velocity. The crane configuration consists of a 1.5-Mg jib BD, a 0.5-Mg jib BC, and a 6.5-Mg counterweight C. The centers of mass for these components are designated as G1, G2, and G3, respectively.

#### Problem Statement

**Objective:**
Determine the resultant moment produced by the load and the weights of the tower crane jibs about points A and B.

**Instructions:**
Express your answers in kilonewton-meters (kN·m) to three significant figures and separate the values by a comma.

**Parameters:**
- Load: 2.2 Mg (2200 kg)
- Jib BD: 1.5 Mg (1500 kg) with center of mass G1
- Jib BC: 0.5 Mg (500 kg) with center of mass G2
- Counterweight C: 6.5 Mg (6500 kg) with center of mass G3

#### Diagram Description

**Figure Analysis:**
The diagram illustrates the tower crane with the following measurements:
- The length from the crane base to the end of jib BD (G1) is 12.5 meters.
- The length from point A (base of the crane) to G2 (center of jib BC) is 9 meters horizontally and a vertical height of 9.5 meters.
- The length from the base to counterweight C (G3) is 7.5 meters horizontally and a vertical height up to G2 is 9.5 meters.
- The crane's vertical column height is 4 meters.

By following the above-mentioned figures and stated problem, students should perform the moment calculation using the formula for moments, ensuring to convert mass in kilograms to force in newtons, and then proceed to calculate the resulting moments about the points A and B. Additionally, remember to take into account the distances given in the diagram when summing up the moments.

#### Required Answer

The final answer must be expressed in the following format:

\[ M_A, M_B = \text{value in kN·m} \]

---

By solving this problem, students will gain a deeper understanding of static equilibrium, moments, and mechanical systems involved in crane operations.

The position of the head and neck and the forces acting on the head are shown in the figure. The center of gravity of the head of mass m=9 kg is located at point C. The joint reaction force of F J = 150 N, which makes an angle of α = 30° with the vertical from the point B, is acting on the skull by the neck extensor muscles. The center of the atlantooccipital joint is located at point B. For this flexion position of the head, the neck muscle force FM, which makes an angle of γ with the horizontal from the point A , is effective .
