Question 14

Materials should be stored on __________ or _____________ to be more easily accessed by a forklift.

Answer 14

Blocks, Pallets

Answer: This is a guideline for material storage.
Explanation: Storing materials on blocks or pallets facilitates easier and safer handling, especially when using forklifts.

Question 15

List two reasons that materials exposed to rain should be stored at a slight angle.

Answer 15

Answer:
a) To allow rain to run off
b) To prevent damage or degradation of materials

Explanation: Storing materials at an angle ensures that water drains off, preventing water accumulation that can cause damage or degradation.

Question 16

List three decisions that are influenced by the weight of a load in any lifting operation.

Answer 16

Answer:
a) Which equipment to use
b) The best rigging materials
c) The best way to secure the load for lifting
Explanation: The weight of the load determines the type of equipment and materials needed for safe lifting, as well as the most secure method to handle the load.

Question 17

When lifting an object, the sling arrangement should position the hook directly above the __________________________.

Answer 17

Answer: centre of gravity

Explanation: Positioning the hook above the load’s center of gravity ensures balance and stability, reducing the risk of the load tipping or falling.

Question 18

If there are no lifting lugs on an object, you can find the centre of gravity and determine sling lengths using the ____________________________ method.

Answer 18

Answer: trial-and-error

Explanation: The trial-and-error method involves cautiously lifting the object partway to observe how it balances, allowing adjustments to be made for proper balance.

Question 19

Calculate the weight in kilograms (kg) of three pieces of steel plate that are 42 mm x 1.4 m x 4 m (h x w x l) in size.

Answer 19

Answer:

Convert measurements to meters: h = 42 mm ÷ 1000 = 0.042 m.

Calculate the volume: Volume = (0.042 m x 1.4 m x 4 m) x 3 = 0.2352 m³ x 3 = 0.7056 m³.

Calculate the mass: Mass = 0.7056 m³ x 7,850 kg/m³ = 5,539 kg.

Explanation: This calculation involves converting measurements, calculating the volume of the plates, and then determining the mass based on the density of steel.
