Ratio of Strain Energy of Bar B to Bar A
Given Information
- Bar A and Bar B are made up of the same material and are of the same length
- Bar A has diameter d while Bar B has diameter 2d
- Both are subjected to the same axial load
Explanation
The strain energy stored in a body is given by the formula:
U = (1/2) x σ x ε x V
where U is the strain energy stored in the body, σ is the stress induced, ε is the strain produced, and V is the volume of the body.
From the given information, we know that:
- Bar A and Bar B are of the same length, so their volumes are the same
- Both are subjected to the same axial load
Therefore, the stress induced in both the bars will be the same.
The strain produced in Bar A is given by:
εA = σ / E
where E is the modulus of elasticity of the material of the bars.
The strain produced in Bar B is given by:
εB = εA / 2
since the diameter of Bar B is twice that of Bar A.
Therefore, the strain energy stored in Bar A is:
UA = (1/2) x σ x εA x V
The strain energy stored in Bar B is:
UB = (1/2) x σ x εB x V
Substituting the value of εB in the above equation, we get:
UB = (1/2) x σ x εA/2 x V
Cancelling out the common terms in the above equations, we get:
UB/UA = (1/2) x εA/2 = 1/4
Conclusion
The ratio of strain energy of Bar B to Bar A is 1:4.
