No. 3. The assembly shown in Figure No. 3 consists of a hollow steel [E = 200 GPa] tube (1) with an outside diameter of 60 mm and a wall thickness of 5 mm, a solid 40 mm diameter aluminum [E = 70 GPa] (2) (3) rod (2), and a solid 30 mm diameter D aluminum rod (3). The member lengths are L1 = 2 000 mm, L2 = 1 200 mm, and L3

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…

At a temperature of 37.4 °C a 0.49-mm gap exists between the ends of the rods shown. At a later time when the temperature has reached 128.7°C, determine the change in length of the steel rod if L = 328.25 mm and M = 215 mm. Round off the final answer to four decimal places.

What do I do when there the angle is not given.
