Consider a rod of length, with a cross-sectional area of The rod supports a , platform that hangs attached to the rod's lower end. What is the elongation of the rod under the stress ignoring the weight of the rod? Consider Young's modulus to be and
- A
- B
- C
- D
Answer & Solution
Correct Answer
(D)
Step-by-step Solution
Detailed explanation
Recall the proper formula of Young's moduls in terms of stress and strain, Y=stressstrain, here stress is defined as force per unit cross-section area and strain is the ratio of increment of lenght and original lenght,…
