In the case of nuts and bolts used on a tube with washers, the load on the bolt is equal to the Load on the tube.

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 the bolt so it will feel tension.

Generally, the bolt is made with cast iron, in cast iron, the tensile stress is more as compared to compressive stress so the bolt is tension and is tube compression.

@All.
First put the bolt into the tube. Just imagine half of the bolt threads exposed the outer end of the tube. Then a nut is placed at that tighten the bolt. Dut to forcefully tightening the nut tube gets compressed. And bolt is already fixed to the tube right. Then pulled oppositely to the action of nut.

Please explain someone.

Nut pulls bolts opposite side while tightening hence tensile and washer faces pushes tube thus compression.

If anyone understands this, kindly explain. How is the bolt in tension?
