Chapter 14, Problem 14.28CP

For the following computer problems, any appropriate software may be used. Input prompts should fully explain what is required of the user (the program should be user-friendly). The resulting output should be well labeled and self-explanatory.

14.28 Write a program that will generate a table of maximum allowable span lengths for a group of $\text{2}$ -in-thick planks (ranging from $\text{4}$ in. to $\text{12}$ in. deep in $\text{12}$ -in, increments) as a function of applied uniformly distributed load. The planks are to bend about their strong axes. Both moment and shear should be considered. The load should range from $\text{5}0$ lb/ft to $\text{12}0$ lb/ft in steps of $\text{1}0$ lb/ft. User input is to be allowable bending stress and allowable horizontal shear stress. Assume the wood to have a unit weight of $\text{35}$ pcf. Use full nominal dimensions.
