State two reasons for using a pneumatic system in a food processing factory
Fig. 3 shows a pneumatic circuit used in a food processing factory to lift food containers from conveyor belt X to conveyor belt Y.
State the logic of the circuit shown in Fig. 3
Describe how the circuit in Fig. 3 operates. Your answer should refer to the function of each component.
A V belt is
used with a gear wheel
used with a pulley wheel
A Tenon saw is
used to cut curved lines
used to cut straight lines
A scriber is:
used to mark lines on metal
used to mark lines on wood
Acrylic is:

A student has used some mild steel tubing in a project and has decided to apply a dip coating to its surface.
State two reasons for dip coating the mild steel tubing
Outline how the mild steel tubing should be prepared prior to dip coating
Three electronic symbols are shown in Fig. 4.
The symbol labelled A in Fig. 4 is an SPST switch. State what the letter P in SPST stands for.
(a)
Name the component labeled B
(a)
Name the component labeled C
(a)
Symbol P in Fig. 5 represents a multi cell battery. State the number of 1.5 volt cells required for a 6 volt multi cell battery.
Complete the circuit in Fig. 5 by adding the Labels for the corresponding symbols for components A, B and C from Fig. 4 in the appropriate spaces.
When the circuit is completed it should enable component C to operate when the switch Sw is pressed for a short time. Assume that component A (the SPST switch) is in the closed position.
Explain the purpose of component B in your completed circuit in Fig. 5
Another partially completed circuit is shown in Fig. 6. When the circuit is complete it should consist of the battery, a bulb and two switches. The bulb should light up when either of the two switches is operated. Add the appropriate symbols and connections to Fig. 6 to enable this to happen.
Fig. 9 shows a greenhouse manufactured from aluminum alloy
Aluminium alloy is a non-ferrous metal. State one other property of aluminum alloy that makes it a suitable material for the greenhouse frame.
Define the term non-ferrous
An alternative design uses softwood to produce greenhouse frames. Name a suitable softwood with appropriate weather resistant properties for the construction of the frame.
Suggest two advantages of the metal-framed greenhouse compared to a wooden-framed greenhouse.
The manufacturer is going to make use of thermochromic pigments in their new greenhouses. Explain the action of thermochromic pigments and state why they would be suitable for use in a greenhouse.
