We have
A = 50 × 75 = 3.75(10−3 ) m 2 , θ = 50o , and σ x = P A .
Equations (1.11), with θ = 50o :
σ x ' = 700(10 3 ) = σ x cos 2 50o = 0.413σ x = 110.18P
or P = 6.35 kN

Refer to Fig. 1.6c. Equations (1.11) by substituting the double angle-trigonometric relations,
or Eqs. (1.18) with σ y = 0 and τ xy = 0 , become
σ x ' = 12 σ x + 12 σ x cos 2θ and τ x ' y ' = 12 σ x sin 2θ
or
20 = P
2A (1 + cos 2θ ) and 10 = P
2A sin 2θ
The foregoing lead to
2 sin 2θ − cos 2θ = 1 (a)
By introducing trigonometric identities, Eq. (a) becomes
4 sin θ cos θ − 2 cos 2 θ = 0 or tan θ = 1 2 . Hence
θ = 26.56o
Thus,
=20 P
2(1300) (1 + 0.6)
gives
P = 32.5 kN
It can be shown that use of Mohr’s circle yields readily the same result.
