A cylindrical bronze sleeve (2) is held in compression against a rigid machine wall by a high-strength st olt (1), as shown in the figure. The steel [E = 200 GPa; a = 11.7 x 106/°C] bolt has a diameter of 29 m The bronze [E = 100 GPa; a = 22.0 x 10-6/°C] sleeve has an outside diameter of 74 mm, a wall thickn f 8 mm, and a length of L = 390 mm. The end of the sleeve is capped by a rigid washer with a thickn ft 5 mm. At an initial temperature of T₁ = 14°C, the nut is hand-tightened on the bolt until the b washers, and sleeve are just snug, meaning that all slack has been removed from the assembly, but no str as yet been induced. If the assembly is heated to Ta 59°C calculate the normal stress (positive if ton =

A rigid bar, AB, is pinned at point B. Two other bars, AC and AD, are connected to point A to provide support for AB. We are investigating the behavior of this system under a specific load. Key Details: Bar properties: Material: Steel with Young's modulus (Esteel) of 200 GPa and coefficient of thermal expansion (a) of 11.7 x 10^-6 /°C. Cross-sectional area: AC: 1960 mm² AD: 1250 mm² Length: AC: √2 meters (square root of 2 meters) AD: 1 meter Inclination angles: AC: θ₁ (theta 1) = 30° from horizontal AD: θ₂ (theta 2) = 20° from horizontal Load on bar AB: Idealized linearly increasing load with a maximum value of 30 kN/m at point B. Problem Objectives: Determine the internal forces (axial forces) acting within bars AC and AD due to the applied load on AB. Calculate the displacement of point A in both horizontal (dA,x) and vertical (dA,y) directions.If the bar is cooled by 10°C, what would be the:  Determine the internal forces (axial forces) acting within bars AC and AD…
