In the given figure a stepped column carries loads. What will be the maximum normal stress in the column at B in the larger diameter column if the ratio of P/A here is unity?
A. 1/1.5
B. 1
C. 2/1.5
D. 2
Answer:C
In the given figure a stepped column carries loads. What will be the maximum normal stress in the column at B in the larger diameter column if the ratio of P/A here is unity?
A. 1/1.5 B. 1 C. 2/1.5 D. 2
Explanation: Normal stress at B = Total load acting at B / Area of a cross-section at B = (P + P) / 1.5 A = 2P/ 1.5A = 2/1.5.
