The closed thin-walled tank has an inner radius of r and wall thickness t and contains a gas of pressure of p. The state of stress at point "a" on the surface of the tank is represented by stress components with an unknown stress element rotation angle of 0. Note that, the two normal stress components for x'y' system (note: not xy system!) are known: ox, = 120 MPa and Oy = 180 MPa, but the shear stress component (T,) is unknown. Determine: (1) the principal stresses at point a ; (2) Tx'yı ; (3) rotation angle of 0 . y 180 MPa 120 MPа х 0 = ? a Tyy = ? tank cross section stress state at point a

A simple pin-connected truss is loaded and supported as shown. The truss is constructed from three aluminum members, each having a cross-sectional area of A = 1480 mm2. Assume a = 1.3 m, b = 6.0 m, and c = 3.6 m. If P = 55 kN and Q = 75 kN, determine the normal stress in each member. P Q Answers: OAB = i овс= i JAC = i a B b с MPa (C) MPa (T) MPa (T)

2. If the allowable shear stress for each of the steel pins at A and B is tpe 6.5 ksi and the allowable normal stress for bar CB is Operm 10 ksi, determine the diameter of the pins at A and B and that of the square bar CB. Pin A is in double shear while Pin B is in single shear. Ignore points D and E. (^ } 2.5 ft -3 ft -5 ft 150 lb/ft Fx =
