Problem 1. [10-38 in the text]. Determine the bulk modulus for each of the following materials:
(a) rubber, Er = 0.4 ksi;! r = 0.48. (b) glass, Eg = 8(10
3)ksi,!g = 0.24.
Problem 2. [10-39 in the text]. The principal strains at a point on the aluminum fuselage of a jet aircraft are !1 = 780(10
!6 )!2 = 400(10
!6 ).
Determine the associated principal stresses at the point in the same plane. Eal =10(10
