Write down which one of the following statements is false:
(A) for a wire of a certain substance and certain cross-sectional
area,
the spring constant is inversely proportional to natural
length
(B) Young's modulus is the gradient of stress as a function of
strain
(C) uids do not have a bulk modulus
(D) spring constant is the gradient of load as a function of
deformation
(E) some substances do not obey Hooke's Law at all
Homework Answers
The false statement among the above statements is :-
(A) for a wire of a certain substance and certain
cross-sectional area,
the spring constant is inversely proportional to natural length
Reason => Because for a specific substance the spring constant does not depends on itsi natural length.

1. During a stress-strain test, the unit deformation at a stress of 5,000 psi was observed to be 0.000167 in./in. and at a stress of 20,000 psi it was 0.000667 in./in. If the proportional limit is 30,000 psi, what is the modulus of elasticity? What is the stress corresponding to a strain of 0.0002 in./in.? Would these results be valid if the proportional limit were 18,000 psi? Explain. 2. A steel wire 30 feet long, hanging vertically, supports...
