Question

ANSWER. *TRUE* (T) or. *FALSE* (F) to the following questions:

A. The elastic limit is the load at which an elastic material breaks.

B. Within the elastic Limit, the strain in a wire doubles if the stress is doubled.

C. The slope of the force vs. extension plot for an elastic string is equal to the young's modulus of the string.

D. If two wires of identical dimensions are subjected to the same stress, the one with the higher young's modulus will show a larger strain.

F. If the tension in an elastic rod is doubled while the overall length of the rod is held constant, the energy stored in the rod is double.​

Answer 1

Answer:

A.True

B.False

C.False

D.True

Answer 2

Answer:

A.  True

B, False

C, False

D, True

Explanation:

A) elastic limit, maximum stress or force per unit area within a solid material that can arise before the onset of permanent deformation. When stresses up to the elastic limit are removed, the material resumes its original size and shape. Stresses beyond the elastic limit cause a material to yield or flow.
