2A rigid bar is supported by two copper rods and the gap (A) between the aluminum rod and the bar is 1.50 mm. If the temperature for all materials is increased by 40 degrees Celsius, what is the thermal stress of the aluminum rod? Disregard theweight of the rigid bar.For each copper bar,A = 500 mm^2, E = 120 GPa, and a = 16.8 μm/(m. C).For the aluminum bar,A = 400 mm^2, E = 70 GPa, and a = 23.1 μm/(m.

A gold-alloy microbeam attached to a silicon wafer behaves like a cantilever beam subjected to a uniform load (see figure). The beam has a length L = 24.5 um and rectangular cross section of a width b = 4.0 pm and thickness t = 0.88 um. The total load on the beam is 14.9 µN. If the deflection at the end of the beam is 1.53 um, what is the modulus of elasticity E, of the gold alloy (in GPa)? (Use the formulas of this example. The beam has constant flexural rigidity EI.)

A steel rod, which is free to move, has a length of 200 mm and diameter of20 mm at a temperature of 15°C. If the rod is heated uniformly to 115°C,determine the length and the diameter of this rod to the nearest micron atthe new temperature if the linear coefficient of thermal expansion of steel is12.5 * 10-6 m/m/°C. Is there a stress on the rod at 115°C?

The assembly shown in the figure consists of an aluminum tube AB and a steel rod BC. The rod is attached to the tube through the rigid collar at B and passes through the tube. The cross-sectional area of the rod is 75 mm2 and the cross-sectional area of the tube is 400 + UV in mm2, where UV is 99. A tensile load of 80 kN is applied to the rod. Take Est = 200 GPa for the steel rod, Eal = 70 GPa for the aluminum tube. Determine: (a) the displacement of end C with respect to end B (i.e., the elongation of the steel rod), (b) the displacement of end B with respect to the fixed end A (i.e., the shrink of the aluminum tube), (c) the displacement of the end C of the rod (i.e., (a) + (b)).
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…
