Figure Q1 shows a structure under a concentrated force of P. Pins A, B, E, and F are single-shear with a 21-mm diameter. The connections at D is double shear connection with a 21-mm diameter. All pins are made of Aluminum 2014-T6. Based on yield stress, minimum factor of safety is 1.5 for all parts of below structure. Determine maximum concentrated force P, that can apply on the structure. (The cross sectional area of members EA and FB are 330 mm² and 250 mm² respectively). 350 mm 600 mm E F 900 mm Copper Brass C83400 Copper Bronze C86100 Figure Q1 A 720 mm P

Problem 17 A joint shown has the basic layout shown in the diagram below. (All dimensions on the diagram are in inches.) A single pin of diameter 0.5 inches (A = 0.2 in2) holds together the yoke and bar as shown. The material has an ultimate strength in tension of 80 ksi, and an ultimate strength in shear of 45 ksi. The load P has a value of 10000 lb. By examining the shear stress in the pin, the normal stress in the yoke, and the normal stress in the bar, find the overall factor of safety for the joint. P=10,000 lb YOKE -0.5 PIN BAR P=10,000 lb 1.5- 20 1.5 0.5 0.5

• Bars (1) have a cross-sectional area of A₁ = 0.65 in.2 and a length, L₁= 7 ft. • Bars (1) are made of cast iron with an elastic modulus of E₁ = 24,000 ksi, a coefficient of thermal expansion, a₁ = 12.3 x 10-6/°F and yield strength of oy = 120 ksi. • Bar (2) has a cross-sectional area of A₂ = 1.45 in.² and a length, L₂ = 5.5 ft. • Bar (2) is made of stainless steel with a coefficient of thermal expansion, a₂ = 10.6 × 10-6/°F. • The stress-strain diagram provided below presents the results of the stainless steel's (i.e., Bar (2)) bar tension test. • There is a gap of A = 0.1 in. in the connection at B and a = 3 ft. • All bars are unstressed before a load P = 12 kips is applied and the temperature increases by AT = 40°F.
