Worked Solution & Example Answer:QUESTION 9: MAINTENANCE (SPECIFIC) 9.1 Name THREE important consequences of failing to conduct preventative maintenance in an engineering workshop - NSC Mechanical Technology Fitting and Machining - Question 9 - 2022 - Paper 1
Step 1
Name THREE important consequences of failing to conduct preventative maintenance in an engineering workshop.
Answer
- Increased Equipment Failure: Without regular maintenance, machines are more prone to breakdowns, leading to increased downtime and costly repairs.
- Safety Hazards: Neglecting preventative maintenance can create unsafe working conditions, which may result in accidents or injuries.
- Decreased Productivity: Inefficient machinery can hinder operations, reducing overall productivity and affecting delivery schedules.
Step 2
State THREE different types of mechanical drive systems.
Answer
- Gear Drive: Utilizes gears to transmit torque and rotational motion efficiently.
- Belt Drive: Employs belts and pulleys to transfer power from one component to another, often used in conveyor systems.
- Chain Drive: Utilizes a chain to transfer power between sprockets, typically used in bicycles and some industrial machinery.
Step 3
Step 4
State TWO properties of Bakelite.
Answer
- Heat Resistance: Bakelite can withstand high temperatures without deforming, making it useful for electrical insulations and kitchenware.
- Chemical Resistance: It is resistant to many chemicals and solvents, which adds to its durability in various applications.
Step 5
State TWO properties of Carbon fibre.
Answer
- High Strength-to-Weight Ratio: Carbon fibre is known for its excellent strength while being lightweight, ideal for aerospace and automotive applications.
- Stiffness: It has a high modulus of elasticity, making it very rigid and suitable for structural components.
Step 6
Step 7
Name THREE ways of conducting preventative maintenance on mechanical equipment.
Answer
- Regular Inspections: Conduct routine visual inspections and checks to identify potential issues early.
- Scheduled Service Intervals: Plan and execute periodic maintenance actions based on usage and manufacturer recommendations.
- Lubrication: Ensure that moving parts are properly lubricated to reduce friction and wear.
Step 8
Name the TWO main types of plastic composites.
Answer
- Reinforced Plastic Composites: These combine plastic with reinforcing materials, such as fiberglass or carbon fiber, to enhance strength and durability.
- Filled Plastic Composites: These incorporate fillers to improve properties like stiffness or reduce costs.
