, The hydraulic press
• Can be created by applying force to a piston with
a small volume and transmitting it through liquid
U2: Investigation skills to another piston with a larger volume.
• The smaller cylinder = input cylinder.
• The larger cylinder = output cylinder.

•
•
2 pistons of different sizes connected by a pipe.
When the smaller piston is moved back and forth by a
handle – it pumps liquid into the cylinder of the larger
piston.
Investigation: design considerations A weak force applied to a small piston raises a heavy
load on a larger piston.
• Design process = using knowledge, skills and resources to
meet needs and wants.
• Solutions must consider social and environmental factors.
• Write a design brief, make the item, evaluate the design
stages and final product, and communicate the design.
