The area of cross section of the rope used to lift a load by a crane is 2.5 x 10 -4 m 2 . The maximum lifting capacity of the crane is 10 metric tons. To increase the lifting capacity of the crane to 25 metric tons, the required area of cross section of the rope should be: (take g=10ms -2 )
Text Solution
Verified by ExpertsThe correct answer is:
A
Since breaking stress (Maximum lifting capacity) is the property of material so it will remain
same.
breaking stress
