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.”
He knew the answer: triangles are rigid. A rectangle can collapse into a parallelogram, but a triangle cannot change shape without changing the length of its sides. He wrote that down. But identifying tension and compression? He guessed. Top members = compression (pushing together). Bottom members = tension (pulling apart). He added a small note: “I think.” technology grade 9 term 2 question paper

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.” Push the small syringe, the larger one moved
