Four steel rods each with a cross-sectional area of 1in 2 are embedded in a 5-in diameter light aggregate concrete cylinder. The steel has a yield strength of 36000 psi and a modulus of elasticity of 30x10n6 psi. Assume a very strong interface between the steel and the concrete causes them to experience identical deflections. A rigid plate is placed over both ends of the cylinder and a compressive axial force of 100,000 lb is applied. The stress (psi) induced...

The assembly is composed of a solid steel alloy rod (Est200 GPa; Vst- 0.32) inside a hollow copper alloy tube (Ecu 101 GPa; vst 0.35). Both the rod and the tube are fixed to a rigid support at A. The length of the assembly is 0.5 m. As shown in figure (b), the diameter of the rod is d1 60 mm, and the outer diameter of the tube is d2-90 mm. The inner diameter of the tube is 70 mm...

a) A hollow circular shaft designed to have an inner diameter of 0.7Do; where Do is an outer diameter.i) Determine the inner and outer diameters of the shaft if the maximum allowable shearing stress is Y0 N/mm2 and torque is X00 kNm. Then, calculate the polar moment of inertia.ii) By using inner diameter calculated in (i), calculate the maximum shearing stress and a new torque, if the shaft is changed to solid circular shaft. The shaft is 1.5 m long with the twisted through...

shown in Figure 2. Two circular disks A and B are welded to the ends of both bars. The disks lie in planes disks A and B subjecting the bars to torsion. If the allowable maximum shear stress is 35 MPa and the allowable rate of twist is 3°/m for both bars, determine the smallest outer diameter (D, and Di) of both bars. The shear modulus of elasticity is 39 GPa to the axes of the bars. Forces 15 kN...

Due to the operational conditions and temperature gradient, a 95 mm diameter, 1.75 m long steel rod within a machine assembly is subjected to a combination of tensile loading of 190 N and thermal loading which imposes a longitudinal force of 244 N. The total loading results in an even distribution of forces on the body of the rod causing it to change its dimensions by increasing 0.45 mm in length at both ends and decreasing by 0.0135 mm at...
