The uploaded image contains two structural problems that involve calculating the reactions for beams and frames with various supports and loads. Here's an outline of both problems:

Problem 1 (Fig. Q.1a):

• Beam with fixed support at A and roller supports at D and E.
• Two internal hinges are located at points B and C.
• The beam is subject to the following loads:
  • A uniformly distributed load (UDL) of 80 kN/m between points A and C.
  • A concentrated load of 80 kN at point C.
  • A UDL of 60 kN/m between points C and E.
  • A moment of 50 kNm applied at point E.
• The lengths between points are as follows:
  • AB = 4 m
  • BC = 2 m
  • CD = 2 m
  • DE = 2 m

You are required to determine all the reaction forces at the supports (A, D, E).

Problem 2 (Fig. Q.1b):

• Frame with multiple members and hinges at points B and D.
• Supports:
  • Fixed support at point A.
  • Roller support at point E.
• Loading conditions:
  • A UDL of 50 kN/m along member AB.
  • A concentrated force of 100 kN at joint D.
  • A moment of 50 kNm at point D.
  • The frame has additional members with known dimensions and loads.

You need to determine the reactions at the supports for this frame.

Would you like to start with Problem 1 or Problem 2? I can break down the solution step-by-step for you. If you'd like further explanation on any concepts like hinge behavior, UDLs, or moment calculations, let me know!

Also, here are 5 questions for further exploration:

1. How does an internal hinge affect the calculation of reactions in a structure?
2. What are the steps involved in calculating the moment reactions at a fixed support?
3. How is the influence of a uniformly distributed load (UDL) different from a concentrated load on a beam?
4. Why are roller supports unable to resist moments, and how does that affect analysis?
5. What are the methods to approach statically indeterminate structures?

Tip: For beams with internal hinges, remember that the moment at the hinge is always zero, which divides the structure into simpler sections.
