A bolt is made to pass through a tube and both of them are tightly fitted with the help of washers and nuts. If the nut is tightened, then

[A].	bolt and tube are under tension	[B].	bolt and tube are under compression
[C].	bolt is under compression and tube is under tension	[D].	bolt is under tension and tube is under compression

Answer: Option D

as the nut is exerting compressive force to the washer ,then ultimately it will compress the tube and if something is compressed it will exert stress(resisting force) here resisting force against compression is tensile stress. so tensile stress will act against bolt so it will feel tension.
