2. Design a circular clarifier for a flow rate of 34,560 m³/d. Use a design overflow rate of 30 m³/d-m². Assume the clarifier has a center feed and a side water depth of 4.3 m. Use a feedwell detention time of 20 min. Provide the following information to support your design: • Diameter of the clarifier • Diameter and depth of the feedwell . Check the flow velocity across the sludge zone • Calculate the weir loading rate

Name: Course: Mechanics of Deformable Bodies Investigation and Design of Axially Loaded Structural Members Date: Term: A. Objective 1. To be able to determine internal axial load on structural members 2. To be able to design structural members with axial internal reactions B. General Instruction 1. Write your solution legibly in separate sheets of clean bond paper. 2. Box your final answer in your solution. C. Situation A truss structure is an assembly of straight structural members that form triangular panels. The assembly of triangular panels makes the truss establish a rigid configuration. In a truss structure, connections are theoretically assumed to act as smooth pin; therefore, it does not resist any moment or bending. Due to this magnificent behavior, truss members only resist axial forces in the design phase that could either be compressive or tensile. Presented in the figure is a truss that is a component of a roof framing system to be constructed at the University Lucena City…

1- A two-lane highway (two 3.6 m lanes) has a posted speed limit of 100 km/h and, on one section, has both horizontal and vertical curves, as shown in the figure below. A recent daytime crash (driver traveling westbound and striking a stationary roadway object) resulted in a fatality and a lawsuit alleging that the 100 km/h posted speed limit is an unsafe speed for the curves in question and was a major cause of the crash. Evaluate and comment on the roadway design (after Mannering and Washburn).

Given a side slope of 2:1, a road width of 10 m and cross-sectional area of 36.4 sq m, for the following cross-sectional notes: 9.8..........0...........x2 y1..........y..........1.2 Determine the value of y.

From station A with center height for 1.4m in fill, the ground makes a uniform slope of 5% to station B whose center height is 2.8 m in cut. Assuming both sections to be level sections having a width of roadway of 14 m and a side slope of 2:1 for both cut and fill, compute the cross-sectional area of fill 48 m from station A. Distance from station A to station B is 60 m.
