(1) The compound rod ABC consists of two cylindrical portions AB and BC. Portion AB is made of a material having modulus of elasticity $E_1$ = 105 GPa while BC is made of aluminum ($E_a$ = 70 GPa). Load P = 100 kN and Q = 800 kN. Determine (a) the normal stress in each material, and (b) the deflection of (i) point A, and (ii) point B Begin your solution on this page. Given: load@P = 100 kN load@Q = 800 kN Modulus of elasticity $E_1$ = 105 GPa BC = $E_a$ = 70 GPa a) Determine the normal stress in each material.
A solid rod of mass M = 1.31 kg and length L = 81 cm is suspended by two strings, each with a length d = 25 cm (see Figure), one at each end of the rod. The string on side B is cut. What is the magnitude of the initial tangential acceleration of end B? d A L The string on side B is retied and now has only half the length of the string on side A. What now is the magnitude of the initial tangential acceleration of end B? d B d/2 B A L
