**Problem 3/54**

The horizontal steel shaft has a mass of 480 kg and is suspended by a vertical cable from point A and by a second cable BC, which lies in a vertical transverse plane and loops underneath the shaft. Calculate the tensions \( T_1 \) and \( T_2 \) in the cables.

**Explanation of Diagram:**

- The diagram shows a horizontal shaft that is 4 meters in length and has a mass of 480 kg. 
- Point A is located 1 meter from the right end of the shaft, and there is a vertical cable from point A to a fixed support, resulting in tension \( T_1 \).
- Point B is located 1.5 meters horizontally to the left of point A and 1.5 meters vertically above the shaft.
- Point C is located 3 meters to the left of point A and vertically above the shaft such that the distance between B and C in the vertical plane is 1.5 meters.
- The second cable \( BC \) spans from point B to point C, with point B attached to the shaft. This cable contributes to the tension \( T_2 \).

In summary, the steel shaft is supported by two tensions:
1. \( T_1 \), acting vertically upward from A.
2. \( T_2 \), acting at an angle due to the cable connecting points B and C.

The problem involves the static equilibrium of the shaft where the sum of the forces and moments must equal zero.
