Stake attention in this memory
An East Asian male instructor delivers a lecture in a classroom in Zhongtun, China. He stands to the right of a large white projection screen, wearing a dark green long-sleeved shirt and glasses. His right hand holds a black pointer, directed at a diagram on the screen depicting three vertical columns under downward force 'F' and upward normal force 'FN', with a query "谁先断?" (Who breaks first?). His left hand is slightly open in a gestural posture. The projection screen displays a slide titled "第一章 绪论" (Chapter One Introduction), including text that translates to "Internal force is related to failure (strength)" and the equation "FN = F". The foreground shows the backs of multiple students seated in rows, observing the lecture. One student in the immediate foreground wears a grey baseball cap and a dark garment with white patterned logos. Overhead fluorescent lights illuminate the classroom. Numerical markings "37" and "43" are visible on a dark panel beneath the projection screen.
