Literature review on behavior of large pile group Pile foundation can be categorized in two types‚ shallow foundation and deep foundation. Both of the foundation plays the same role which is to transfer the loading from the structure above to the ground. Shallow foundation a part of the whole structure. Its plays an important role in transferring the load from the structure to the ground. There are several material used for the pile such as timber‚ steel and concrete. The piles are drive‚ drilled

Translational motion Translational motion is the aspect in which a body moves from a specific point to the next. This can be in terms of objects‚ molecules or atoms. This kind of motion normally takes place in a straight line for instance bullet which is fired by a gun. The object in motion does not change by turning on its axis for it travels in a straight line. Any slight change or rotation can cause the object to change direction in general making it not move toward the specified direction.

Abstract Static equilibrium of forces was investigated through the use of different weights attached to cords which were connected to a central ring‚ while pulleys supported them. This assembly facilitated the force band system to demonstrate that equilibrium will be attaining regardless of disturbances. However‚ due to errors in the experiment‚ the sum of the x and y component did equate to zero as predicted. The graphical solution of the experiment yield a polygon that is completed indicating

(e.g.) Fluid in a reservoir (or) in a settling chamber. 5. Distinguish between static and stagnation pressures. In stagnation pressure state‚ the velocity of the flowing fluid is zero whereas in the static pressure state‚ the fluid velocity is not equal to zero. 6. Differentiate between the static and stagnation temperatures. The actual temperature of the fluid in a particular state is known as “static temperature” whereas the temperature of the fluid when the fluid velocity is zero

Assume the boxes each have masses of 2.0 kg‚ the coefficient of static friction is µs between table and box‚ and the acceleration due to gravity is 10 m/s2 . 001 10.0 points A block accelerates 3 m/s2 down a plane inclined at angle 27.0◦. The acceleration of gravity is 9.81 m/s2 . 1. The force of the static friction would have a vertical component in this situation‚ and that is impossible since it must be parallel to the table surface
