Which of the below brick bonds would be the weakest?
-
Flemish bond
-
Common bond
-
Stack bond
-
Running bond
Correct Answer
A. Stack bondExplanation
A stack bond is the weakest brick bond because it involves laying bricks directly on top of each other without any overlapping or interlocking. This lack of interlocking makes the bond more susceptible to lateral forces and can cause the bricks to easily separate or shift. In contrast, other brick bonds like Flemish bond, Common bond, and Running bond involve overlapping and interlocking of bricks, providing greater strength and stability to the structure.Rate this question:

On an open web joist 43 feet long, what would be the approximate camber needed?
-
1/4 inch
-
1/2 inch
-
5/8 inch
-
3/4 inch
Correct Answer
A. 3/4 inchExplanation
The approximate camber needed on an open web joist 43 feet long would be 3/4 inch. Camber refers to the slight upward curve or arch that is intentionally built into a joist to counteract the deflection caused by the weight it will bear. In this case, the length of the joist is relatively long, which requires a larger camber to ensure proper support and prevent sagging or bending over time. Therefore, the approximate camber needed is 3/4 inch.Rate this question:
