Answer:
False, True , True.
Step-by-step explanation:
Buckling is defined as large lateral deflection of member of under compression with slight increase in load beyond a critical load.
1) Buckling occurs in axially loaded member in tension. is false as buckling occurs in tension.
2) Buckling is caused by lateral deflection of the member and not the axial deflection. hence true.
3) Buckling is an instability phenomenon that can lead to failure. Hence True.
