Question
The bar is subjected to a moment of M = 100 N # m. Determine the maximum bending stress in the bar and sketch, approximately, how the stress varies over the critical section.
Expert Solution
Step 1
Given
Moment = 100 Nm
D = 80 mm = 0.08 m
d = 20 mm = 0.02 m
t = 10 mm = 0.01 m
r = 10 mm = 0.01 m
To find
Maximum bending stress
Diagrammatically representation of stress in critical area
Step 2
Stress concentration
