A steel bolt $\left( \text { area } = 130 \mathrm {~mm} ^ { 2 } , E _ { s } = 210 \mathrm { GPa } \right)$ is enclosed by a copper tube (length = 0.5 m, area = $\left. 400 \mathrm {~mm} ^ { 2 } , E _ { c } = 110 \mathrm { GPa } \right)$ and the end nut is turned until it is just snug. The pitch of the bolt threads is 1.25 mm. The bolt is now tightened by a quarter turn of the nut. The resulting stress in the bolt is approximately:

The Answer of A steel bolt  $\left( \text { area } = 130 \mathrm {~mm} ^ { 2 } , E _ { s } = 210 \mathrm { GPa } \right)$ is enclosed by a copper tube (length = 0.5 m, area = $\left. 400 \mathrm {~mm} ^ { 2 } , E _ { c } = 110 \mathrm { GPa } \right)$ and the end nut is turned until it is just snug. The pitch of the bolt threads is 1.25 mm. The bolt is now tightened by a quarter turn of the nut. The resulting stress in the bolt is approximately:

A Steel Bolt ( area =130 mm2,Es=210GPa)\left( \text { area } = 130 \mathrm {~mm} ^ { 2 } , E _ { s } = 210 \mathrm { GPa } \right)( area =130 mm2,Es​=210GPa)
