For all S1: Revision Notes 3 (Design)
Hi all,
A recap on design........
A design brief is a short statement stating the purpose on how to solve a design problem.
It starts with ..........Design and make a product ...........
E.g. Design and make a product that shows directions.
A design specifications state the requirements for your design in terms of functions, appearance, size, choice of materials, safety, etc..
It usually starts with........... The product should .........
E.g. The product should be waterproof as it is meant to be placed in an outdoor open space.

For All Sec 1: Revision Notes 2 (Structure - Types of forces)
Hi All,
You need to know the different type of forces acting on the member of a structure.
In summary,
1. A compression / compressive force will cause a member of structure to be squashed. The member that is in compression is called a strut.
2. A tension / tensile force cause a member of structure to be stretched. The member that is in tension is called a tie.
3. A torsion / torsional force cause a member to be twisted.
4. A shear force cause a member to slide/tilt to a side.

Structure terms
1. Beam - A member of a structure that is supported on two ends to resist bending.
Eg: Bench
Eg: Diving Board, Wings of airplane, Ceiling fan
3. Strut - A member of structure that is subjected to compression.
4. Tie - A member of structure that is subjected to tension.
