6 Clearly state all assumptions made towards solving the problem 1) Deformable links BD and CE are attached to a, rigid link ABC at B and C by pins with a,
negligible diameter. Link ED is made of brass (EBT : 15 X 103 “1,057; = 15 1652') and has a
cross—sectional area, of 0.4 in? Link CE is made of aluminum (EA; : 10 X 103 ksl, 0511i : 8 ksi)
and has a cross—sectional area, of 0.5 mg. Determine (a) The largest load P that can be applied at A, if the the deformable links are to be designed
for a factor of safety of 3.0 l 28% £1,673 (b) The corresponding deﬂection of A
(25 pts) I) L ~~>+~< 9.0 in. —»l 5.0 int 2) The steel shaft ABCD (G3,: = 27 01%) is held ﬁxed at A and D, Determine (a) The reaction torques at A and D (b) The maximum shear stress in portion BC

a) The plate, shown in ﬁgure, is subjected to a biaxial state of normal stress 0’35 : 200 M’Pa
and or; 2 60 M Pa. Determine the %age Change in the length of diagonal BD (10 pts) b) The thin hollow brass shaft, shown in ﬁgure, has an allowable shear stress of Tau 2: 12 ksi. :
