Stress developed due to application of a load suddenly is ______ times that due to same load Being applied gradually.
2.0
Since the load increases linearly from 0 to P, the work done is the average load multiplied by the total deformation (\delta L_{gradual}). The work done by this sudden load is simply the load P multiplied by the deformation \delta L_{sudden} because the load P is acting at its full value over the entire deformation. Therefore, the correct answer is 2.0.
