Required information

Problem $07\mathrm{.}015-$ Determine the normal and shearing stresses after rotation of the element for the given state of stress.

Given: $P=16\mathrm{.}5$ksi

Problem $07\mathrm{.}015.$a $-$ Determine the stress components after clockwise rotation of the element for the given state of stress.

Determine the normal and the shearing stresses after the element shown has been rotated through $25$ clockwise. $($Round the final answers to two decimal places.$)$

Normal stresses:

${}_{x^{\text{'}}}=,$ ksi $(+$ tensile; $-$ compressive$)$

${}_{y^{\text{'}}}=,$ksi $(+$ tensile; $-$ compressive$)$

Shearing stress:

${}_{x^{\text{'}}{y}^{\text{'}}}=,$ ksi $(+$ CCW on positive $x-$face$)$
