1.A polystyrene rod consisting of two cylindrical portions AB and BC is restrained at both ends and supports two 6 kip loads as shown. Knowing that E = 0.45 * 10^6 psi, determine the reaction C.
2.An axial force of 200 kN is applied to the assembly shown by means of rigid end plates. Determine the normal stress in the aluminum shell.
3.A nylon thread is to be subjected to a 10-N tension. Knowing that E=3.2 GPa, that the maximum allowable normal stress is 40 MPA, and that the length of the thread must not increase by more than 1%, determine the required diameter of the thread.
