Textbook Question
Chapter 10, Problem 10.1P
In adjusting measured traverse angles‘ why aren’t adjustments made in proportion to the angle sizes?
Expert Solution & Answer
To determine
The reason why the adjustments are not made in proportion to the angle sizes in adjusting measured traverse angles.
Answer to Problem 10.1P
Error is independent of angle size and depends on the method used for measurement.
Explanation of Solution
In elementary methods of traverse adjustment, the first step is to balance the angles to the proper geometric total. For a closed traverse angle balancing is easy since the total error is known. Angles of the closed traverse can be adjusted to the total geometry by any of the following methods:
- Applying an average correction to each angle of the traverse.
- Making larger corrections where the observations and measurements are not done properly.
In a closed traverse, if a single angle is not measured accurately then, error occurring due to one observation reflects in other observations. It is independent on the size of the angle and depends on the method used while measuring the angles. Therefore, adjustments are not made in proportion to the angle sizes in measured traverse angles.

A major transmission pathway of the novel coronavirus disease 2019 (COVID- 19) is through droplets and aerosols produced by violent respiratory events such as sneezes and coughs (Fig. 1). For the purpose of providing public health guidelines, we would like to estimate the amount of time it takes for these droplets to settle from air to the ground. The relevant parameters are the settling time (ts), the initial height of the droplets (H), gravitational acceleration (g), density of the droplets (pa), radius of the droplets (R), as well as dynamic viscosity of the ambient air (Pair). Use dimensional analysis and the Buckingham theorem to answer the following questions: 1. Find the independent dimensionless parameters using the table method. Then, express the settling time as a function of the other relevant parameters. Your solution should match the physical intuition that the settling time scales linearly with the initial height. 2. How would the settling change if the…arrow_forward
- Question 4 An engineer is assigned to design a 25-stories office building which has a building height of 75 m. Reinforced concrete shear wall system as shown in Figure Q1(a) is adopted to resist the lateral loads. The shear wall is of thickness t = 350 mm and length L = 8.5 m. Use the following data: Young's modulus of concrete E = 28 kN/mm² and the lateral load intensity w = 1.20 kN/m². Assuming the frontal width of the building façade is 15 m is facing the wind force which in turn transmitting the wind force to the shear wall system, estimate the total value of sway A at the roof level.

- Question IV (30%): A 22 m thick normally consolidated clay layer has a load of 150 kPa applied to it over a large areal extent. The clay layer is located below a 3.5 m thick granular fill (p= 1.8 Mg/m³). A dense sandy gravel is found below the clay. The groundwater table is located at the top of the clay layer, and the submerged density of the clay soil is 0.95 Mg/m³. Consolidation tests performed on 2.20 cm thick doubly drained samples indicate the time for 50% consolidation completed as t50 = 10.5 min for a load increment close to that of the loaded clay layer. Compute the effective stress in the clay layer at a depth of 16 m below the ground surface 3.5 years after the application of the load.arrow_forward13-3.
