Specialisation plays a crucial role in the management of a farm to ensure success in the agricultural sector - NSC Agricultural Technology - Question 5 - 2018 - Paper 1

1. Buildings: This includes barns, storage facilities, and shelters for animals or equipment.

2. Equipment: Machinery such as tractors, plows, and irrigation systems.

1. Protects the machine: The shear bolt serves as a safety mechanism, preventing damage to the baling machine components by breaking if excessive force is applied.

2. Prevents overload: It helps to control the amount of material being taken into the baler, ensuring it does not become overloaded.

A = Pressure plate B = Release bearing C = Clutch plate

No, a vehicle with a locked differential cannot effectively turn around a bend. When the differential is locked, both wheels on the axle rotate at the same speed, which prevents the wheels from turning independently. This would cause the inner wheel to slip and lead to potential loss of control or excessive tire wear.

1. Bearings reduce friction: They allow for smoother operation and increased efficiency in the machinery.

2. Extended lifespan: Properly used bearings can significantly prolong the lifespan of the moving components by minimizing wear.

1. Light weight: Thermoplastic materials are generally lighter, which can improve overall machine efficiency.

2. Corrosion resistance: These joints are less likely to corrode, enhancing durability in various environmental conditions.

The drawing should clearly display the ratchet plate, pressure spring, driven gear with ratchet plate, and the adjusting nut.

1. Stability: Rear fork lifts lower the center of gravity, reducing the risk of tipping over while handling heavy loads.

2. Visibility: Using a rear fork lift allows the operator to maintain a better view of the load and surroundings.

When the top link is removed, the plough may lift out of the soil, causing a disruption in the ploughing process and potentially leading to uneven soil disturbance.

1. Two lifting arms.

2. Top link.

1. Pickup system: Ensuring it is set correctly to gather all kernels.

2. Drum speed: Setting it correctly to minimize kernel damage.

3. Gear/pulley adjustments: Ensuring they are monitored for optimal performance.

1. Ensure all hammers are replaced at the same time for balance.

2. Regular maintenance: Check for any loose parts that may cause imbalance.

3. Run mechanical components at the correct speed to minimize vibrations.

1. Where the top link is fitted.

2. At the base of the lifting arms.

1. Not compressible: Allows for effective transmission of force.

2. Good lubrication qualities: Reduces wear and tear on components.

3. Contains anti-foam detergent: Keeps the system clean and operational.

The total area to be painted is 9 m². With a coverage capability of 3 m² per litre, for TWO coats:

1. Total paint required = \

   \ ext{Area Covered per Litre} = 3 ext{ m}^2
   \ ext{Total area for 2 coats} = 9 ext{ m}^2 imes 2 = 18 ext{ m}^2
   \ ext{Litres required} = rac{18 ext{ m}^2}{3 ext{ m}^2/ ext{litre}} = 6 ext{litres}

   
   Therefore, the amount of paint required is 6 litres.
