Question
**Team Problem 7-1: Lateral-Torsional Buckling**

A W27x94 beam made of Gr. A992 steel is being used to support the factored live loads shown. You may neglect the self-weight of the beam. Is the beam adequate to support the given loads?

**Diagram Explanation:**

- The beam is labeled as W27x94, which indicates its size and weight per unit length.
- The beam is supported at each end. On the left, there is a simple support, and on the right, there is a roller support.
- The total length of the beam is divided into three equal sections of 12 feet each, totaling 36 feet.
- Two loads are applied to the beam:
  - A 75 kip load at 12 feet from the left end.
  - A 30 kip load at 24 feet from the left end.
- Arrows indicating the direction of the loads show they are acting downward on the beam.

The question asks whether the beam can adequately support these loads, considering potential lateral-torsional buckling effects.
