Two solid cylindrical rods (1) and (2) are joined together at flange B and loaded as shown. If F₁ = 15 kips, F₂ = 34 kips, and the normal stress in each rod must be limited to 17 ksi, determine the minimum diameter d₂ required for rod (2). A (1) (2) d₁ F₂ B d₂

A rigid bar AB of length L = 1600 mm is hinged to a support at A and supported by two vertical wires attached at points C and D such that AC = 500mm and AD = 1200mm Both the wires have same cross sectional area of 16 mm² and made of the same material having Young's modulus of 200 GPa. The wire at C has a length of 400 mm and that at D has 800 mm. Determine the tensile stresses in the wires and downward displacement at point B of the bar when a load of 1 kN is suspended at B.

Rigid bar ABC is supported by a pin at bracket A and by tie rod (1). Tie rod (1) has a diameter of 8 mm, and it is supported by double- shear pin connections at B and D. The pin at bracket A is a single-shear connection. The pin at B is 5 mm in diameter. Assume a = 570 mm, b = 285 mm, h = 360 mm, and 0= 65°. If the normal stress in tie rod (1) cannot exceed 190 MPa and the shear stress in pin B cannot exceed 120 MPa, determine the maximum load Pmax that can be supported by the structure.
