Question
Chapter 18, Problem 1RQ
To determine
The difference between coniferous tree and a deciduous tree.
Expert Solution & Answer
Answer to Problem 1RQ
The difference between them is that coniferous trees are softwood whereas, deciduous trees are hardwood.
Explanation of Solution
Wood is a natural organic material and is a unique among construction materials as it is renewable. Woods are mainly categorized into softwoods and hardwoods. Coniferous trees are softwood which bears cones with a few exceptions having a needle like leaves. Deciduous trees are hardwood having bread leaves and they shed their leaves during winter.

A borrow-pit (i.e., a place where soils are excavated, to then be placed elsewhere for construction projects) has been identified with e = 0.74, emax = 0.9, emin = 0.5. To avoid excessive road deformations, the soil will be compacted to a relative density of DR = 90% when placed in the embankment. Your boss estimates that extracting 100,000 m^3 of material from the borrow-pit should be enough for this project. Is your boss correct, or is more material than that needed? To decide, answer these questions: a) What volume of soil, as placed, is required to build the embankment? [Tip: draw the embankment] b) What is the void ratio of the material when placed in the embankment? c) What is the relative density of the material in the borrow-pit? d) When soil is extracted from the borrow-pit and then compacted it the embankment, how do…arrow_forwardThere are 20 cars traveling at constant speeds on a 1 mile long ring track and the cars can pass each other freely. On the track 25% of the cars are traveling at 20 mph, 50% of the cars are traveling 10 mph, and the remaining 25% of the cars are traveling at an unknown speed. It was known that the space mean speed of all the cars on the track is 20 mph. (a) What is the speed that the remaining 25% of cars are traveling at? (b) If an observer standing on the side of the track counted the number and measured the speed of all cars that passed her for one hour, what is the time-mean speed of all the cars the observer counted? (c) What is the flow rate measured by the observer? (d) What is the car density on the track? Does density times space mean speed equal flow rate?arrow_forward
