Problem: Design a doubly reinforced rectangular simply supported beam to support an unfactored moment due to dead load of 325 k-ft and an unfactored live load moment of 400 k-ft. The concrete compressive strength is 4000 psi and the yield strength of steel is 60,000 psi.
Question 1: Design the compression and tension steel assuming the beam cannot be more than 36"tall and 18"wide, use d = H -3".
Question 2: Design the compression and tension steel assuming the beam cannot be more than 31"talland 14"wide, use d = H -3".
Use these results to determine the maximum normal stress in the material.
When in use, a fishing rod can be approximated to act as a cantilevered beam. Assume that the force (P) is applied to the end of the beam by a fish while the fisherman rigidly holds the other end of the beam.
Drainage facility: - Drainage facility is the normal or fake evacuation of surface and sub-surface water from a territory. Numerous rural soils need waste to enhance creation or to oversee water supplies

Determine the bending moment in a rectangular beam 2 in. wide and 4 in. deep, if the maximum bending stress is 20,000 psi.
Assume the microorganisms are 55 percent efficient at converting food to biomass, the organisms have a first-order death rate constant of 0.05/day, and the microbes reach half of their maximum growth rate when the BOD5 concentration is 10 mg/L
Determine whether a jump may occur at an initial depth of 0.5 m or not. If a hydraulic jump occurs, determine the sequent depth (conjugate depth) to this initial depth
