Largest Bridge on the earth

-

Danyang-Kunshan Grand Bridge (2010)

This 102.4 mile (164.8 km) bridge holds the title of world's longest, and it took four years to construct. Unlike most bridges, it is built in a viaduct design, spanning many valleys and connecting the cities of Shanghai and Nanjing in the Jiangsu province of China. The railway that the bridge connects spans 818 mi (1317 km), which is an engineering feat of its own.

Brick

Brick Composition of Good Brick Earth Following are the constituents of brick earth: 1. Alumina It is the chief constituent of every kind of clay. A good brick earth should contain about 20 to 30 per cent of alumina. This constituent imparts plasticity to earth so that it can be moulded. 2. Silica A good brick earth should contain about 50 to 60 per cent of silica. Presence of this constituent prevents cracking, shrinking and warping of raw bricks. It thus imparts uniform shape to the bricks. Excess of silica destroys the cohesion between particles and bricks become brittle. 3. Lime It should be present in a finely powdered state and not in lump. Lime prevents shrinkage of raw bricks. Sand alone is infusible. But it slightly fuses at kiln temperature in presence of lime. Excess of lime causes the brick to melt and hence, its shape is lost. Lumps of lime are converted into quick lime after burning and this quicklime slakes and expands in presence of moisture. 4....

DIFFERENCE BETWEEN MAIN BARS AND DISTRIBUTION BARS

MAIN BARS AND DISTRIBUTION BARS In any reinforcement detailing there are two sizes of bars used in the slab. That is main reinforcement bars and distribution bars. In this article, we will discuss the difference between main bars and distribution bars. To understand properly we need to know the bending moment on a slab. Let’s take an example. When a lo ad is applied to a slab the bottom of the slab will experience positive moment (Sagging) and the supports will experience negative moments (Hogging). The bottom part, as well as the top part of the slab, will experience high tension at the same time.     The deflection will be very high in shorter span and low in longer span. A high amount of tension will be acting in the support which is near than the other one. FUNCTION OF MAIN REINFORCEMENT BARS: Main reinforcement bar is provided at the shorter span direction in order to transfer the bending moment developed at the bottom of the slab. The purpos...

Properties of fluid

Fluid Properties Basic Concept The branch of the mechanics that deals with bodies at rest is called  statics  while the branch that deals with bodies in motion is called  dynamics . Fluid statics → Study the behaviour of fluid at rest or at motion study fluid at Rest. Fluid kinematics → Study of Fluid at motion without considering pressure. Fluid dynamic → Study of fluid at motion with considering pressure. A substance in liquid / gas phase is referred as ‘fluid’. Distinction between a solid & a fluid is made on the basis of substance’s ability to resist an applied shear (tangential) stress that tends to change its shape. A solid can resist an applied shear by deforming its shape whereas a fluid deforms continuously under the influence of shear stress, no matter how small is its shape. In solids, stress is proportional to strain, but in fluids, stress is proportional to ‘strain rate.’ Illustration of solid and fluid deformation Referring to Fig., t...
