Answer:
Option b) False
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."
Answer:
Check the explanation
Explanation:
To calculate or compute the magnitude of the velocity at whichever point in time, you’ll need to multiply the constant acceleration pace times the amount of time difference and then adding the result to the initial velocity
While To calculate or compute the horizontal component, the magnitude of the vector will just be multiplied by the cosine angle referenced to the horizontal

Answer:
Damping ratio 
Explanation:
Given that
m=4.2 kg,K=85.9 N/m,C=1.3 N.s/m
We need to find damping ratio
We know that critical damping co-efficient


N.s/m
Damping ratio(
) is the ratio of damping co-efficient to the critical damping co-efficient
So 


So damping ratio
