Massachusetts Construction Supervisor License (CSL) Practice Test

In a single family dwelling with an 8:12 roof pitch and a cricket height of 12 inches, what is the width of the cricket?

1. 24 inches

2. 30 inches

3. 36 inches

4. 42 inches

The correct answer is: 36 inches

To determine the width of the cricket in a single-family dwelling with an 8:12 roof pitch and a cricket height of 12 inches, one needs to consider the geometry involved in the roof structure. A cricket is a small, raised section on the roof designed to divert water away from a chimney or other protrusion. The width of the cricket can be calculated using the roof pitch and the vertical height of the cricket. In this case, the 8:12 pitch means that for every 12 horizontal units, the roof rises 8 vertical units. This ratio can also help us understand how to translate the vertical height of the cricket into horizontal distance. Given that the cricket height is 12 inches, we can apply the slope defined by the roof pitch. The relationship can be established as follows: 1. The vertical rise of 12 inches can be converted into horizontal distance using the 8:12 rise/run ratio. 2. To find the width, we can set up a proportion based on the pitch of the roof: - For every 8 units of vertical rise, there is a corresponding 12 units of horizontal run. - Therefore, to find the horizontal distance (width) for a 12-inch rise,
