The image shows a person using a soldering iron. (a) Give two safety precautions that you should follow when using a soldering iron.
1. Wear safety goggles to protect your eyes. 2. Do not touch the tip of the soldering iron as it is very hot.
1. Use bare hands to hold the hot tip. 2. Keep the soldering iron close to your face.
1. Dip the soldering iron in water while it is plugged in. 2. Touch the hot tip to check if it is working.
1. Use the soldering iron on wet surfaces. 2. Leave the soldering iron unattended while switched on.
Give one disadvantage of using the soldering process when modelling circuits.
It can be difficult to correct mistakes once components are soldered in place.
It always increases the speed of the circuit.
It makes the circuit wireless automatically.
It prevents any kind of electrical faults from occurring.
One-off/jobbing production techniques are sometimes used when making engineered products. Identify two reasons why one-off/jobbing production techniques are used.
Because robots can complete repetitive operations
To produce a unique product
Because product demand is low
To make use of low skilled labour
To allow for continuous processing
One reason for using a MIG welding process to join metal is:
It provides a clean and efficient weld.
It requires no electricity.
It is only suitable for plastic materials.
It does not use shielding gas.
Select two advantages of using a robot in a nuclear waste processing environment.
Reduces human exposure to radiation and increases efficiency
Increases human exposure to radiation and decreases efficiency
Reduces the need for safety protocols and increases manual labor
Decreases automation and increases risk of human error
One disadvantage of using an assembly robot in a low volume motorsport production cell is:
High initial cost is not justified by low production volume.
Robots improve flexibility for small batch sizes.
Assembly robots reduce the need for skilled labor in all cases.
Robots are always faster than manual assembly in low volume production.
Give two properties of cubic boron nitride that make it a suitable material for machining superalloys.
1. High hardness 2. High thermal stability
1. Low electrical conductivity 2. High ductility
1. High electrical conductivity 2. Low melting point
1. Low hardness 2. High reactivity
Identify the carriage on the diagram of the centre lathe. Click on the part of the diagram that shows the carriage.
The carriage is the part located in the middle of the lathe, beneath the tool post and above the lead screw.
The carriage is the large wheel on the right end of the lathe, used to rotate the spindle.
The carriage is the base of the lathe, supporting all other components.
The carriage is the tailstock, located at the far right end of the lathe.
The diagram shows a centre lathe. Where would the workpiece be gripped? Click on one of the boxes.
Tailstock
Chuck
Lead screw
Tool post
One advantage of using hydro energy as a renewable energy source is that it produces clean electricity. Which of the following is a disadvantage of using hydro energy?
It can disrupt local ecosystems and fish habitats.
It produces a lot of air pollution.
It is not a reliable source of energy.
It requires fossil fuels to operate.
Identify the die on the diagram of the die casting process. Click on the part of the diagram that shows the die.
The die is the grey block at the end of the horizontal channel where the molten metal is injected.
The die is the orange channel where the molten metal flows.
The die is the blue container holding the molten metal.
The die is the red plunger pushing the molten metal.
Powder metallurgy is a four-stage modern manufacturing process used in engineering. What is the first stage of the powder metallurgy process? Click on one of the boxes.
Powder blending
Compacting
Powder manufacture
Sintering
One advantage and one disadvantage for a manufacturer of making its products recyclable are:
It helps the environment but may increase production costs.
It reduces costs and increases pollution.
It makes products less durable and harder to sell.
It decreases customer satisfaction and increases waste.
You are a manufacturing engineer working for an automotive windscreen manufacturer. You need to reply to this text message: 'I've heard you are offering a nanocoating on the windscreens you manufacture. What is the advantage of using surface nanotechnology on your windscreens?' Explain one advantage of using surface nanotechnology for this application.
One advantage is that surface nanotechnology can make windscreens more resistant to water, dirt, and scratches, improving visibility and durability.
Surface nanotechnology makes windscreens heavier and more opaque, reducing visibility.
Surface nanotechnology increases the electrical conductivity of windscreens, making them unsuitable for vehicles.
Surface nanotechnology causes windscreens to absorb more heat, leading to frequent cracking.
Which of the following is a benefit of using robots in hazardous manufacturing environments?
They reduce the risk of injury to human workers.
They always require manual operation.
They increase the need for human presence in dangerous areas.
They make processes slower and less efficient.
What is one reason why powder metallurgy is used to manufacture complex parts?
It allows for precise control over material composition and shape.
It always produces parts with low strength.
It is only suitable for making plastic components.
It requires no specialized equipment.
Which property makes cubic boron nitride suitable for cutting tools used on hard materials?
High electrical conductivity
Low melting point
High hardness
Low thermal stability
