How to Determine Reactions at Fixed End E in a Frame System?

What is the tension in the cable supporting a part of the roof of a small building?

Tension in cable = 260 kN

What are the reactions at the fixed end E of the frame?

Choose the correct option:
A. Vertical reaction only
B. Horizontal reaction only
C. Both vertical and horizontal reactions

Answer:

The reactions at fixed end E consist both of vertical and horizontal components that keep the frame system in equilibrium.

When dealing with a frame system supporting a part of a roof, it is essential to understand how to determine the reactions at the fixed end E. In this scenario, the tension in the cable plays a crucial role in maintaining equilibrium in the system.

By knowing the value of the tension in the cable, which is 260 kN, we can analyze the forces acting on the frame to find the reactions at fixed end E. These reactions include both vertical and horizontal components that work together to keep the frame stable.

The vertical reaction at fixed end E is responsible for balancing out the weight of the roof, which is supported by the tension in the cable. On the other hand, the horizontal reaction at fixed end E counteracts the horizontal component of the tension in the cable to ensure the frame remains in equilibrium horizontally.

Understanding how these reactions interact and contribute to the stability of the frame system is crucial for structural analysis and design. By applying the principles of equilibrium and Newton's laws, we can accurately determine the reactions at fixed end E based on the given tension in the cable.
