Reference excerpt

The Thomas Ranck Round Barn is a round barn in Waterloo Township near the Fayette-Wayne County, Indiana county line. It is one of many round barns built in Indiana during the late 19th and early 20th centuries. Of the round barns built in eastern Indiana during this period the Ranck Round Barn stands out as one of the most elaborately designed structures. The Thomas Ranck Round Barn was listed on the U.S. National Register of Historic Places in January 1983. Built in 1904, the Ranck Round Barn is a large and wood frame barn. It is part of a complex of buildings on the southeast portion of the McDivitt property in Brownsville, Indiana. Erected on a bank with a concrete foundation, the barn is 70 feet (21 m) in diameter, and is 70 feet (21 m) tall. The open structure consists of three circular tiers stacked on top of one another. The top section forms a cupola. Isaac McNammee constructed the Ranck Barn in 1904 for Thomas and Nancy Ranck. McNammee built several round barns in the area, and patented his design for a self-supporting conical roof in 1905. The Ranck farm was purchased in 1937 by a local veterinarian and his wife, Ralph and Tena Carmack. In 1945, Emmett and Mary McDivitt purchased the property.

Exterior This perfectly round structure has no central support system of timbers. With the exception of some timbers on the lower level, no structural member is more than 2.5 inches (6.4 cm) thick. The main floor is raised above the surrounding ground, and the lower level, is at grade. The exterior is covered with vertical wood siding, painted white. The lower level is made of studs about 2'6" on center. Joists span in various directions to make a platform for the second level. At this level the main drum has studs with rhythmically spaced angle bracing reaching to the upper first roof plate. These braces are paired and spaced and have intermediate stiffening diagonals. Each upper drum rests on a laminated sill/plate, which apparently acts as a tension ring. An earthen ramp slopes up to the main entrance for the upper level on the west side. The doorway is in a projecting bay with a low gambrel roof. It has two sliding wooden doors consisting of three horizontal panels, with diagonally bracing in the top and bottom panels. At grade access is provided on the north side. Another pair of wooden doors once hung from the shed roof overhang, which has been removed. The barn roof is a series of truncated cones. The cupola has a conical cap. The roof is covered in gray asphalt shingles. The overhanging eaves have exposed rafters and fascia. Small windows provide light and ventilation on the main and lower floor. At the loft level, there are small, square, fixed windows around the building. In the cupola, square, louvered vents]] have replaced the windows, which were the same shape as those at the loft level.

Interior The lower level has a concrete floor with access from the north. Stock pens are arranged around the perimeter. A central circular walkway allows access to all of the stalls. An interior stairway leads to the main level. The main level has an earth floor. Divided by wood partitions, the floor serves as a storage area for equipment and supplies. On this level is a one-story wooden corncrib. Two grain bins, 10 by 15 feet (3.0 by 4.6 m) are located in the center. The interior is open to the roof of the cupola. A hayloft extends overs about 1/3 of the main floor. It is supported by paired brackets and diagonal beams placed between the brackets in each pair.

Significance The Ranck, or McDiyitt, Round Barn is significant as one of the best-preserved of Indiana's round barns. This local landmark is essentially unaltered, and has been well maintained over the years. The barn has no system of central support for its three-tier roof, and few structural members more than. 2 ½ inches thick. Its remarkable construction makes it an outstanding example of stick carpentry engineering.

Design The Ranck Round Barn is 70 feet in diameter at its base and stands 70 feet tall. The barn features two rows of clerestories set between round lantern conical roofs which decrease in size with height. The building's west entrance has a pavilion with a gambrel roof.

Worked examples

Example 1 — a first encounter with Thomas Ranck Round Barn

Start with the simplest possible case. Write down what Thomas Ranck Round Barn claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Thomas Ranck Round Barn before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Thomas Ranck Round Barn ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Thomas Ranck Round Barn

In research: Thomas Ranck Round Barn appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Thomas Ranck Round Barn in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Thomas Ranck Round Barn is common in secondary-school and first-year university syllabi. It links to neighbouring topics Barns on the National Register of Historic Places in Indiana, Buildings and structures completed in 1904, Buildings and structures in Fayette County, Indiana, so understanding it makes those chapters shorter.
In everyday life: Look for Thomas Ranck Round Barn outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
