Many homes and commercial buildings have rain gutters. The gutters were originally designed to divert water away from the foundation of the building and thus prevent water damage. Most gutters are fabricated on the construction site. This allows the gutters to be as long as needed (no seams) to fit the building. Assume you have 12 inch wide flat sheet metal to bend upwards to form right angles

Goal: Is Car and Driver correct? Learn the difference in the stopping distance of a car when driving while texting vs. not texting.Drivers today have many distractions that can keep them from applying braking as soon as possible. One of the biggest distractions while driving is texting. Many times drivers believe that a quick, short text is doable while driving. In this lab, you will collect

Many homes have small gables along the front of the home. The photo at right shows an example of the type of gable above the front door that we are constructing for this year's house. The width of the gable immediately above the front door is 10 feet.The main roof has a 3/12 pitch. The small gable will have a 3/12 pitch. It may be helpful to build a model of this portion of the roof out of balsa

A Fun Look at Economics and the ParabolaGoal: Students will simulate a factory that has the ability to add workers but can not add capital resources. Students will create a product called Nutterflutters in the class. The production process of the product will be analyzed mathematically. Background information for the teacher: All CTE areas include an element of business and how to be successful

The fascia board is a vertical board along the edge of the roof. It is designed as a way of enclosing the end of the rafters of a home. The white board in the photo is a fascia board. Because it is used as a trim/decorative board, the cuts and joints must be precise. The angle (located in the red circle) can be a tough angle to calculate. Many carpenters do not calculate this angle, but instead

In recent years the size and shape of drink cans have been varied. The traditional looking pop can is no longer the only option in purchasing your 12 oz (355 ml) soda. Half size pops, Monster drinks, coffee drinks, etc have filled the grocery shelves. Your task is to design a cylindrical can (355 ml) that minimizes can production costs. The production costs can be minimized by using the smallest

The high school plans to allow the Biology class to build a mini-zoo for small animals such as mice, hamsters, snakes, tarantulas, guinea pigs, etc. Due to budget limitations, costs will be a big concern and design economies must be considered. The cages will be built using 4 ft by 8 ft plywood sheets and 4 ft by 8 ft Plexiglas sheets as the materials. Eight cages will be built. Each cage needs

Stairs are a challenge to design. The outdoor deck shown is 11 feet 4 inches above the concrete base ( 4 feet by 4 feet by 4 inches deep). The treads are 11 inches wide. The building code states the stairs are to be at most 30 degrees with the ground and the riser height should be between 6 inches and 8 inches. The rise must be the same for all steps. Note that building codes vary by region.

Concrete Slump TestTesting Concrete for StrengthWater Amount_________ (Given by the teacher)The concrete slump test is, in essence, a method of quality control. For a particular mix being used on a construction site, the slump should be consistent. A change in slump height would demonstrate an undesired change in the ratio of the concrete ingredients. If this were to happen, the proportions of the

Mathematics appears in unusual places. When grocery stores are designed, an architect must calculate the space needed for storage of the shopping carts. The cart above is 39” long, 22” wide and has a nesting distance of 13.5”. Nesting distance is how much extra length a cart takes when the carts are stacked together. One cart takes up a 39” length and 2 carts take up 52.5” length. Write
