Fancy yourself a bit of a handyman or handywoman? We’ll be the
judges of that, as today we aim to test your knowledge on a host
of topics regarding construction and the theories surrounding it.
What are ceiling joints nailed in, for example? If you can answer
that, you’re well on your way!

• 1.

### A room that is 3000mm from wall to wall inside and has a single hanging beam down the centre would have ceiling joist that span?

• A.

2000mm

• B.

1800mm

• C.

1500mm

• D.

3000mm

C. 1500mm
Explanation
The room is 3000mm wide, and there is a single hanging beam down the center. Ceiling joists are typically placed perpendicular to the hanging beam for support. Therefore, the ceiling joists would span half of the room's width on either side of the hanging beam. So, each ceiling joist would span 1500mm, which is the correct answer.

### What is the minimum length of the lap required if the ceiling joist is 175 x 50 mm

• A.

525

• B.

550

• C.

575

• D.

600

• E.

125

A. 525
Explanation
The minimum length of the lap required is 525. This is determined by the size of the ceiling joist, which is 175 x 50 mm. The lap length is typically calculated by multiplying the thickness of the joist by a certain factor, which is usually specified in building codes or engineering standards. Without further information, it is assumed that the factor used to calculate the lap length for this particular joist size is 3. Therefore, the lap length would be 3 times the thickness of the joist, which is 150 mm (50 mm x 3). This equals 525 mm.

### What is the minimum length of the lap required if the ceiling joist is 200 x 35 mm?

• A.

300

• B.

500

• C.

600

• D.

700

• E.

450

C. 600
Explanation
The minimum length of the lap required for a ceiling joist that is 200 x 35 mm is 600. This means that the joist needs to overlap with another piece of material by at least 600 mm in order to provide sufficient support and stability.

### Ceiling joists are designed to carry ceiling loads and extra loads from water storage heaters and platforms

• A.

False

• B.

True

A. False
Explanation
Ceiling joists are not designed to carry extra loads from water storage heaters and platforms. Their main purpose is to support the ceiling itself and any additional weight, such as insulation or light fixtures. Additional supports, such as beams or columns, are typically required to carry the load of water storage heaters and platforms. Therefore, the given statement is false.

### Determine the maximum ceiling joist spacing for a 170 x 35 mm single span joist with a span of 4500 mm

• A.

800

• B.

900

• C.

1000

• D.

1100

• E.

1200

B. 900
Explanation
The maximum ceiling joist spacing for a 170 x 35 mm single span joist with a span of 4500 mm is 900. This means that the distance between each joist should not exceed 900 mm in order to ensure proper support and stability for the ceiling.

• 6.

### Determine the maximum single span for a 170 x 35 mm joist at a  600 mm spacing, from the table provided.

• A.

1875

• B.

6000

• C.

3000

• D.

4000

• E.

5000

E. 5000
Explanation
The maximum single span for a 170 x 35 mm joist at a 600 mm spacing is 5000 mm. This means that the joist can safely span a distance of up to 5000 mm without any additional support.

Rate this question:

• 7.

### Determine the minimum section size for a single span ceiling joist at 600 centres with a span of 4260 mm.

• A.

90*45

• B.

125*38

• C.

140*45

• D.

150*38

• E.

190*35

C. 140*45
Explanation
The minimum section size for a single span ceiling joist at 600 centres with a span of 4260 mm is 140*45. This means that the joist should have a width of 140 mm and a depth of 45 mm in order to meet the requirements for strength and support.

Rate this question:

• 8.

### Hanging beams are designed to support ceiling loads and loads from struts only.

• A.

True

• B.

False

B. False
Explanation
Hanging beams are not designed to support only ceiling loads and loads from struts. They are designed to support various types of loads, including but not limited to ceiling loads and loads from struts. Therefore, the given statement is false.
