The room exhaled. Papers were collected. Thabo leaned over to Lerato. “What did you put for the tension-compression thing?”
Ms. Dlamini, walking between rows, glanced at Lerato’s paper and smiled ever so slightly.
Thabo’s pencil trembled. He could see the gears in his head—turning, meshing, reversing direction. But his hands produced something that looked like three lumpy circles with teeth that resembled a child’s drawing of a sawblade. He added arrows: driver clockwise, idler anticlockwise, last gear clockwise. He hoped Ms. Dlamini would have mercy.
“Time’s up. Pens down,” Ms. Dlamini announced. technology grade 9 term 2 question paper
“You may begin,” Ms. Dlamini said, her voice calm but firm.
was a mixture of short answers and diagrams. Question 2 showed a cross-section of a simple hydraulic press with two cylinders—a small master cylinder and a larger slave cylinder. The diagram was unlabeled, and the question read: “Identify parts A, B, and C and explain how force is multiplied in this system.”
“Mostly,” Thabo said, grinning.
TERM 2 EXAMINATION MARKS: 100 TIME: 3 HOURS
Thabo, sitting in the third row, stared at the cover sheet as if it were a cryptic puzzle. He had studied. Sort of. He had watched three YouTube videos on gears the night before and had even drawn a pulley system in the margins of his notebook. But now, with the clock ticking toward the invigilator’s command to “turn over your papers,” his mind felt like a clogged drainage pipe—slow and likely to overflow with the wrong things.
The paper sat on Ms. Dlamini’s desk, a pristine stack of thirty-four stapled booklets. The front page read, in bold Times New Roman: The room exhaled
With thirty minutes left, Thabo went back to the questions he’d skipped. He reread the bridge structural member one. Transfer loads. Yes. He filled it in. He checked his gear train diagram and added a label for the idler gear. He counted his marks: if he got half of Section A, half of B, most of C, a few in D, and full marks in E, he might just scrape 55%. A pass.
“A small rural clinic needs a device to lift a 50 kg water tank from ground level to a platform 1.5 meters high. The clinic has no electricity. The device must be simple, safe, and built from locally available materials.”
Thabo, meanwhile, was stuck on . There was a diagram of a roof truss—a complex web of triangles. Question 9 read: “Identify which members are in tension and which are in compression. Explain why triangles are used in trusses.” “What did you put for the tension-compression thing
Thabo knew this was the core of the term’s work. He remembered Ms. Dlamini’s demonstration with two syringes and a tube of water. Push the small syringe, the larger one moved with more force but less distance. He scribbled: “A is the master piston. B is the slave piston. C is the hydraulic fluid (oil or water). Force is multiplied because pressure is the same in both cylinders, but force = pressure × area. Bigger area = bigger force.”
The rustle of pages turning was like a sudden wind through a dry forest. Thabo flipped to . His eyes landed on Question 1.1:
