For the composite rod of Prob. 2,107, if P is gradually
Chapter 2, Problem 2.108(choose chapter or problem)
For the composite rod of Prob. 2.107, if P is gradually increased from zero until the deflection of point C reaches a maximum value of \(\delta_{m}=0.3 \mathrm{~mm}\) and then decreased back to zero, determine, (a) the maximum value of P, (b) the maximum stress in each portion of the rod, (c) the permanent deflection of C after the load is removed.
