Answer:
Option b) False
Step-by-step explanation:
The given statement for a prismatic bar having constant area of cross section
is not correct and hence False as the length of the bar is not infinite.
The length of the prismatic bar must be very large in comparison to the thickness and width of the bar but has finite length and is not infinite.
Therefore, the correct statement is:
"In plane stress, a prismatic bar with constant area of cross section has finite length."
