The scale of the USGS 7 1/2- minute quadrangle map

Answer to Problem 18.1P
1:24,000
Explanation of Solution
Given Information:
USGS 7 1/2 - minute quadrangle map
USGS map divides the area into quadrangle map shown by area in the terms of latitudes and longitudes within 2 lines. 7.5 minute shows the area bounded by 7.5-degree latitude and 7.5-degree longitude. Scale of 1:24,000 provides enough details through the quadrangle map.
Most of the natural features and geographical information is shown in the scale of 1:24,000 and these maps are generally used by engineers, architects, city planners, etc. Other maps with larger scale are also available such as 1:50,000 and 1:1,00,000 and these maps are preferred for management activities and land use pattern identification.

- The single degree of freedom (SDOF) system that you studied under free vibration in Assignment #3 - Laboratory Component has been subjected to a strong ground motion. The acceleration at the base (excitation) and the acceleration at the roof (response) of the SDOF system was recorded with sampling rate 50 Hz (50 samples per second, or dt= 0.02 seconds). The file ElCentro.txt includes the two columns of acceleration data. The first column lists the acceleration at the base of the SDOF system. The second column lists the acceleration at the roof of the SDOF system. (a) Plot the time histories of the recorded accelerations at the base and at the roof of the SDOF system. (b) Compute the acceleration, velocity and displacement time histories of the roof of the SDOF system subjected to the recorded base acceleration using the Central Difference method. Plot the accel- eration, velocity and displacement time histories. Plot the restoring force, the damping force, and the inertia force time…arrow_forwardPlease explain step by step and show formulaarrow_forwardPlease explain step by step and show formulaarrow_forward
