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

QUESTION: 119

Which type of deformation does a stressed body undergo after the limit of proportionality has been crossed?

Solution:

For stresses beyond the elastic limit, a material exhibits plastic behavior. This means the material deforms irreversibly and does not return to its original shape and size, even when the load is removed. When stress is gradually increased beyond the elastic limit, the material undergoes plastic deformation.

Hence, the correct option is (A)

QUESTION: 120
