Construction Master 5: Slope and Measurements

The video tutorial demonstrates how to use the Construction Master 5 calculator to solve right angle problems, specifically focusing on calculating the slope or drop of surfaces like driveways and lots. It explains how to input measurements, use the rise key for vertical changes, and understand the resulting slope in terms of pitch, percent grade, and degrees. The tutorial also provides examples of different scenarios and concludes with information on where to find additional resources.

What is the primary function of the Construction Master 5's right angle solution keys?

• To find the volume of a container

• To measure the length of a wall

• To determine the drop or slope of a surface

• To calculate the area of a room

In the driveway example, what is the length of the run?

• 48 feet 2 inches

• 50 feet

• 47 feet 7 inches

• 45 feet 5 inches

What is the initial pitch used in the driveway example?

• Quarter-inch per foot

• Half-inch per foot

• Three-eighths inch per foot

• One-eighth inch per foot

After adjusting the pitch to one-eighth inch per foot, what is the new drop?

• 5 and 15/16 inches

• 7 and 3/4 inches

• 11 and 7/8 inches

• 6 and 1/2 inches

What is the percent grade when the pitch is one-eighth inch per foot?

• 0.5 percent

• 1.04 percent

• 2 percent

• 1.5 percent

In the lot example, what is the total run measured?

• 150 feet

• 137 feet 9 inches

• 130 feet 2 inches

• 140 feet 5 inches

What is the vertical change in the lot example?

• 3 feet 2 inches

• 2 feet 10 inches

• 3 feet

• 2 feet 5 inches

What is the calculated slope for the lot example?

• Half-inch per foot

• Quarter-inch per foot

• One-eighth inch per foot

• Three-eighths inch per foot

What is another way to express a quarter-inch per foot slope?

• 1.18 degrees

• 2.5 degrees

• 3 degrees

• 0.5 degrees

What is the percent grade equivalent to a 1.18-degree slope?

• 1 percent

• 1.5 percent

• 2.5 percent

• 2 percent
