A (a) is a set of things or parts or processes that work together to achieve an output or perform a
function.
A (a) is a device used to manage or regulate a
system.
(a) are block diagrams used to describe a system. Here each operation within the system is represented by a block. Each block has an input and
output.
list and define the two types of system that you know
list 5 examples of common application of system and control
(a) are the outcomes or the end results of the system.
(a) are the activities that transform the inputs into new forms. examples include; painting, cutting and laminating.
(a) are the things that are put into the system. examples include– the physical materials, energy and labour supplied.
(a) are usually simple linear processes that has no feedback to control the system.
(a) are processes that use feedback such as sensors to control the output of the system.
list 3 differencies between open-loop systems and closed-loop systems
What is the purpose of flowcharts?
To visualize the steps and flow of a process
To write code for algorithms
To communicate complex systems
To store and update data
Which symbol is used to indicate the start or endpoint of a flowchart?
Process Symbol
Terminator Symbol

(a) are simply things that are designed for specific purposes to provide support.
Most structures are systems that are made up of parts called (a)
List the three classification of structures
.
(a) are structures that rely wholly on their weight and the weight of the materials used to make them to resist pressure or external force
.
These are structures that are made using very thin layers of materials called sheets.
(a)
.
These are structures that are made by connecting individual parts (called members) together to form a rigid structure that is capable of supporting more load and resisting higher pressure without deflecting
too much..
(a)
These are vertical structural members used to support beams. They are designed to resist compression, bending and twisting.
(a)
These are horizontal structural members used to support load spanning across a gap. They are
designed to withstand/resist bending.
(a)
List the 3 types of forces that acts on a structure
These are forces that tends to push the structure/member in the direction of the force from a fixed position.
(a)
These are forces that tends to squash structures/members
(a)
These are forces that tends to stretch structures/members
(a)
these are members used to resist compression.
(a)
these are members used to resist tension
