This image captures an interior scene within a classroom or lecture hall in Rukn ad-Din Municipality, Syria. The upper portion of the frame is dominated by a large white dry-erase board displaying engineering or physics content in black marker. On the left side of the board, a structural diagram illustrates a beam subjected to a uniformly distributed load of "25 kN/m" and a horizontal point load of "20 kN". The beam segments are labeled with lengths "6m" and "3m", and flexural rigidities "EI" and "2EI", accompanied by the note "EI = const". The right side of the whiteboard features mathematical equations, primarily involving calculations for deflection "Δ", such as "Δ = (1/EI) * l * (aA+bB)/3" and subsequent numerical steps like "Δ = (1/EI) * 8 * (200x10^4)/3" leading to "Δ = 1/EI * (8 x 2000)/3". Arabic text, specifically "الباب الأول" (Chapter One), is written at the top right of the board. A person, likely an instructor, is visible on the far left, extending their right arm, dressed in a light-colored long-sleeved garment, holding a marker and actively writing on the whiteboard. Below the whiteboard, a dark-colored table or counter surface spans the width of the frame. A red and black whiteboard eraser rests on this surface to the right. To the left, a stack of white papers or notebooks is present. Below the whiteboard and above the table, dark wooden paneling is visible, interspersed with several white electrical outlets. A tangle of black electrical cables or wires lies on the table near these outlets. A label "A-4" is affixed to the front edge of the table. In the immediate foreground, the backs of three individuals' heads are visible, indicating they are seated students facing the whiteboard. The leftmost individual has dark, curly hair. The central student has short, dark hair, with a portion of a light-colored shirt collar visible. The third student on the right is partially obscured.
