Question

The concrete post (Ec = 3.6 × 106 psi and αc = 5.5 × 10-6/°F) is reinforced with six steel bars, each of 78-in.78-in. diameter (Es = 29 × 106 psi and αs = 6.5 × 10-6/°F).

Determine the normal stresses induced in the steel and in the concrete by a temperature rise of 75°F. 

 

 

The image shows a rectangular prism with the following dimensions: the base measures 10 inches by 10 inches, and the height of the prism is 6 feet. The top face of the prism is annotated with several small circles, which could represent openings or features, but their specific details are not indicated. The base's measurements are labeled as "10 in." on each side, and the height is labeled as "6 ft." This diagram can be used in mathematics or engineering contexts to demonstrate volume and surface area calculations, or in physics to model a solid structure.
