Question

The length of a suspended wire increases by 10^4 of its original length. when a stress of 10 ^7 Nm^-2 is applied on it. calculate the young'son modulus of the material of the wire

Answer 1

✳️✳️✳️ANSWER✳️✳️✳️

A wire 2 m long and 1 mm in diameter, when stretched by weight of 8 kg has its length increased by 0.24 mm. Find the stress ... Solution: Given: Initial length of wire = L = 3 m, radius ofwire = 0.5 mm = 0.5 × 10-3 m, = 5 × 10-4 m,Force applied =49 N, Young's modulus for steel = Y = 2.1 × 1011 N/m².

Answer 2

Answer:

Explanation:

HEYA HERE IS YOUR ANSWER.

∆l=10−4l

∆l=10−4=strain

Stress=107 N/m2Young's modulus, Y=stress

strainY=10710−4

=1011 N/m2
