Calculate the weight of a reinforced concrete beam that has a cross section b=15″and h=28″. Span length is 25ft

In a simply supported beam, where does the maximum bending moment occur?

What is the ultimate limit state for reinforced concrete beams?

Determine the amount of steel area required for a beam with b=10″, h=18″, f’c=4,000 psi, fy=60,000 psi and Mu=145 k-ft. Choose a size and amount of bars and check for beam width.

Cell A has half as much DNA as cells B, C, and D in a mitotically active tissue. Cell A is most likely in ________.  

A radish is a root vegetable that produces flowers that may be red, purple, or white. A cross between a red-flowered plant and a white-flowered plant yields all-purple offspring. The part of the radish we eat may be oval or long, with long being the dominant trait. If true-breeding red-flowered, long radishes are crossed with true-breeding white oval radishes, the F1 will be expected to exhibit which of the following phenotypes?  

In the cells of some organisms, mitosis occurs without cytokinesis. This will result in ________.  

If the DNA content of a diploid cell in the G1 phase of the cell cycle is x, then the DNA content of the same cell at metaphase of meiosis I will be ________.  

Which of the following scenarios describes an example of epistasis?  

The mitotic spindle plays a critical role in which of the following processes?
