The fundamental pitch of a CC tuba is 32 Hz, and for a BB â­ tuba, 29 Hz. The CC tuba is used as an orchestral instrument in the U.S., but BB â­ tubas are the contrabass tuba of choice in German, Austrian, and Russian orchestras.
Settlement: When a load is applied on the ground, it increases the vertical effective stress. This stress increases the vertical strain in the soil. This increase in vertical strain causes the ground to move downward. This downward movement of the ground is called settlement. Many civil engineering projects include placing of loads on the ground, which produces increase in vertical effective stress. This increase in vertical stress is important because it produces vertical strain in the soil. Subsidence:
Settlement geography is a branch of geography that investigates the earth's surface 's part settled by humans.t should be understood that buildings are one tangible expression of man-land relationships and that specification of this focus assumes study may be at any scale from quite general to most specific; there is no restriction to large-scale study of individual building plans or architectural details.
