Question

The maximum load that a wire can sustain is W. If the wire is cut to half its value, the maximum load it can sustain is

Answer 1

Answer:

it will be same

Explanation:

becouse breaking stress doesn't depends on length of wire

Answer 2

 If the wire is cut to half value, the maximum load is can sustain will be same.

1. As the Breaking strength formula = Maximum stress applied * Area of                               cross section on which load is applied.

2. Here Breaking strength is same as maximum load.

3.  Since here Maximum stress applied will be decided by external factors and the area of cross section will be 3.14*radius*2 ( if the cross section is circular).

4. As we can see there is no dependency on the length of the wire. Therefore any alteration in the wire length will not affect the sustaining capacity of the wire.

5. So here on cutting the wire into half of its length the maximum load it can sustain will remain same.
