Solution:
Zone of high pressure with anticlockwise wind.

Tropical cyclone, also called typhoon or hurricane, an intense circular storm that originates over warm tropical oceans and is characterized by low atmospheric pressure, high winds, and heavy rain. Drawing energy from the sea surface and maintaining its strength as long as it remains over warm water, a tropical cyclone generates winds that exceed 119 km (74 miles) per hour.

QUESTION: 105

Irrigation canals are generally aligned on-

Solution:
Watershed canal or ridge canal:

The dividing ridge line between the catchment areas of two streams (drains) is called the watershed or ridge canal.

Thus, there is the main watershed (ridge line) between two major streams, which divides the drainage area of the two streams, as shown in figure below. Similarly, between a main stream and any of its tributary, there are subsidiary watersheds (ridge lines), dividing the drainage between the two streams on either side.

The canal which is aligned along any natural watershed (ridge line) is called a watershed canal, or a ridge canal. Aligning a canal (main canal or branch canal or distributary) on the ridge ensures gravity irrigation on both sides of the canal.

Since the drainage flows away from the ridge, no drainage can cross a canal aligned on the ridge. Thus, a canal aligned on the watershed saves the cost of construction of cross-drainage works.

Hence, the correct option is (A)

QUESTION: 106

The design shear strength in concrete depends on

Solution:
When the amount of tension steel increase, the depth of neutral axis increases and thus, the depth of uncracked concrete increase. This increases the capacity of shear. When the amount of tension steel increases, the cracks formed are smaller, which improves the aggregate interlock. Also because of larger steel area the dowel action is improved. This further improvs the capacity of section is shear.

Hence, the correct option is (C)

QUESTION: 107
