Question

Statement (I): Hoe is not very advantageous in digging trenches and basements.

Statement (II): In a hoe, the digging action results from the drag of the bucket.
1. Both Statement (I) and Statement (II) are individually true and Statement (II) is the correct explanation of Statement (I)
2. Both Statement (I) and Statement (II) are individually true but Statement (II) is not the correct explanation of Statement (I)
3. Statement (I) is true but Statement (II) is false
4. Statement (I) is false but Statement (II) is true

Answer 1

Correct Answer - Option 4 : Statement (I) is false but Statement (II) is true

Concept:

Hoe:

It is an excavating equipment of the power shovel group. Since the digging mechanism resembles to an ordinary garden hoe, it is named as Hoe. But it is referred by several names such as hoe, backhoe, back shovel and pull shovel.

In a hoe, the digging action results from the drag of the bucket.

The special feature of hoe is in its rigidity. That’s why it is superior to the dragline or power shovel. As the hoe is able to exert greater tooth pressure, it is commonly used in quarries which have tough digging conditions.

In general, a hoe may be used to

1. Excavate below the natural surface of the ground on which the machine rests.

2. Dig trenches, footings or basements and general grading work which requires precise control of depths.

3. Operate on close range work and dump into trucks.

4. Penetrate easily into toughest materials to be dug.

So statement 1 is wrong here.
