The three rods are made of A-36 steel and form a pin-connected truss as shown. The assembly is stress- free at 50 °F. Determine the force in each bar when the temperature of the assembly is increased to 110 °F. The cross-sectional area of each bar is 2.5 in². A 4 ft 3 ft 3ft US

Two solid cylindrical rods (1) and (2) are joined together at flange B and loaded as shown. If F₁ = 13 kips, F₂ = 34 kips, and the normal stress in each rod must be limited to 22 ksi, determine the minimum diameter d₁ required for rod (1). A (2) d₁ F₂ B C O 1.087 in. O 0.823 in. O 0.541 in. O 0.867 in. O 1.003 in. d₂

At a temperature of 20 °C there is a gap ∆ = 0.2 mm between the lower end of the brass bar and the slab rigid suspended from the two steel bars.  Neglecting the mass of the slab, determine the stress in each bar when the temperature of the assembly rises to 100°C  Answer: σsteel = 15.462MPa (t), σbronze= 20.615MPa(c),

Review Part A The 50-mm-diameter cylinder is made from Am 1004-T61 magnesium and is placed in the clamp when the temperature is T = 20°C. (Figure 1) If the 304-stainless-steel carriage bolts of the clamp each have a diameter of 12 mm, and they hold the cylinder snug with negligible force against the rigid jaws, determine the force in the cylinder when the temperature rises to T2 = 130°C.
