Question

Statement (I): The forward edge of wheels or outriggers acts as a fulcrum in determining the lifting capacity of a mobile crane.

Statement (II): There are in-built security and safety against sudden dropping of load, as well as against abrupt swinging, in the working of a mobile crane.
1. Both Statement (I) an 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 2 : Both Statement (I) and Statement (II) are individually true but Statement (II) is not the correct explanation of Statement (I)

Statement I: True

The fulcrum (location where the distance from the force multiplied by the force equals the distance of another force multiplied by another force) is located where the shaft is on the crane. It determines the lifting capacity of the crane. This is the reason due to which it does not fall to one side is because there is a counterweight on the crane on the other side of the fulcrum where,

Distance from the fulcrum × Magnitude of the weight of counterweight = Weight of the object the crane is carrying × Distance from the fulcrum

Mobile crane may be permitted, when specified, to move on their wheels or tracks when carrying loads or may require the use of stabilizers or outriggers to permit the lifting of their design loads.

For mobile crane, the forward edge of wheels or outriggers acts as a fulcrum in determining the lifting capacity of a mobile crane.

Statement II: True

There are in-built security and safety against sudden dropping of load, as well as against abrupt swinging, in the working of a mobile crane.

But statement (II) is not correct explanation of statement (I)
