Question 1:
Diagram 1 shows an experiment to study the transmission of pressure in liquid by hydraulic system. A weight is added on the big piston’s syringe. The suitable weights are added on the small piston’s syringe until both pistons are at the same level. The weight added represents the force acting on both pistons.
The result of the experiment is shown in Table 1.
(a) Based on the result in Table 1, draw a graph to show the force acting on the small piston against the force acting on the big piston on the graph paper provided. [2 marks]
(b) Based on the graph in 1(a), what is the force acting on the small piston if the force acting on the big piston is 8 N? [1 mark]
Answer:
(a)
(b) 3.2 N (± 0.1)
(c) Volume of water
(d) Hydraulic brake / Hydraulic jack
