Question
Chapter 16, Problem 1P
To determine
The two sources of water of which highway engineer is concerned about.
Expert Solution & Answer
Answer to Problem 1P
Two sources of water of which highway engineer is concerned about is given below,
- Surface drainage
- Subsurface drainage
Explanation of Solution
Two sources of water of which highway engineer is concerned about is given below,
- Surface drainage
- Subsurface drainage
Surface drainage:
Generally, the main source of surface water is precipitation which is occurring from the rain and snow. From this, some of the water may get absorbed into the soil and some of it may remain on the surface. This water should be removed at the time of pavement construction. This will be the concern of a highway engineer.
Subsurface drainage:
The second source, ground water, flows into streams of underground. It may become important in cuts of highway or at places, where a high-water table exists near the structure of pavement. This source of water is known as subsurface drainage.

Bars AD and CE (E=105 GPa, a = 20.9×10-6 °C) support a rigid bar
ABC carrying a linearly increasing distributed load as shown. The
temperature of Bar CE was then raised by 40°C while the temperature of Bar
AD remained unchanged. If Bar AD has a cross-sectional area of 200 mm²
while CE has 150 mm², determine the following: the normal force in bar AD, the
normal force in bar CE, and the vertical displacement at Point A.

- The single degree of freedom system shown in Figure 3 is at its undeformed position. The SDOF system consists of a rigid beam that is massless. The rigid beam has a pinned (i.e., zero moment) connection to the wall (left end) and it supports a mass m on its right end. The rigid beam is supported by two springs. Both springs have the same stiffness k. The first spring is located at distance L/4 from the left support, where L is the length of the rigid beam. The second spring is located at distance L from the left support.arrow_forwardFor the system shown in Figure 2, u(t) and y(t) denote the absolute displacements of Building A and Building B, respectively.
