- A composite section 2 m in length, consisting of a steel tube with outer diameter 24 mm and thickness 3 mm, encloses a solid copper bar 18 mm diameter. An axial compressive load of 250 KN is applied on the assembly. Young’s modulus for steel and copper are taken as 2 x 105 N/mm2and 1 x 105N/mm2respectively. Calculate the stresses developed in steel and copper. Also calculate the load taken by both the materials.Calculate the bursting pressure for a cold drawn seamless steel tubing of 60 mm inside diameter with 2 mm wall thickness. The ultimate strength of the steel is 380 MN/m2.(a) 25 MN/m2(b) 20 MN/m2(c) 30 MN/m2(d) NoneA disk of SBR elastomer 3.0 cm in diameter 0.5 cmthick is used as a cushioning surface between two steel rods ofthe same diameter, as shown below (not to scale). a. If the rods are brought together with an axial force of 100 N such that the SBR is compressed elastically between them, what is the thickness of the SBR under load? b. Under the same conditions as part (a), what is the greatest possible diameter of the SBR under load? c. If the SBR is bonded to the rods, how far can one rod be rotated with respect to the other before the SBR/rod interface fractures? Assume that the rods are essentially rigid and the distance between them remains constant. Please answer in degrees of rotation.
- Compute the relative change in resistance, ΔR/R, if a piezoresistive device experiences stress of 20 MPa in one direction. Use a value of 3.84 GPa for Young's modulus of the piezoresistive material. Express your answer in three decimal places.A team of design engineers are designing an amusement park structure as in Figure 2below. The horizontal beam supporting the gondolas at both ends are supported by 2vertical bars, bar EB and bar CF with a cross sectional area of 11,100mm2 and 9,280mm2each. Gondola 1 (left) weighs 380 kN and Gondola 2 (right) weighs 360kN respectively. Due to theweight of both the gondolas, the design team needs to investigate the verticaldisplacements of both ends of the horizontal beam at A and D. You are required to helpthem analyze and calculate the vertical displacement at both ends due to the weight ofthe gondolas.[Please Write Clean and Provide Complete Explanation] One end of a 2 m long steel rod (d = 3 cm) is rigidly attached to a wall so that the rod is perpendicular to the wall. The other end of the rod is welded to a second rod, which is 1 m long (d = 1.0 cm). The second rod is parallel to the wall and the floor. A vertical force of 50 N is applied to the end of the second rod. For both rods, the modulus of elasticity is 210 × 109 Pa and the shear modulus is 79 × 10 9 Pa. There is an infinitesimally small cubic element at the top surface of the 3 cm diameter rod immediately adjacent to the wall, that is, at (0, 1.5, 0). What is most nearly the maximum normal stress due to the bending moment?
- In Problem 1.32, if the rod is snugly fitted against two immovable nonconducting walls at a temperature of 15°C and then heated uniformly to115°C, what is its length at 115°C? If the modulus of elasticity of steel is207 GPa, what is the stress induced in the bar? Is this stress tension orcompression?A composite bar is fabricated by brazing aluminum alloy [E= 10,000 ksi] bars (1) to a center brass [E= 17,000 ksi] bar (2). Assume w= 1.25 in., a= 0.25 in., L= 40 in. If the total axial force carried by the two aluminum bars must equal the axial force carried by the brass bar, calculate the thickness b required for brass bar (2).Consider the steel pressure vessel shown in Figure 1, intended to withstand an internalpressure of 40 MPa. The vessel has an outer diameter of 300 mm, an overall length of 500mm and a wall thickness of 30 mm. There is a 30 mm fillet radius where the interior wallsurface joins the end caps, as shown in the section view in Figure 1. The vessel is made ofASTM A27 steel. Use ANSYS Workbench to simulate this component and comment on itssuitability for production given the loading conditions detailed above.
- Find the equivalent stresses at Points 1 and 2 of the element with given geometry and loading conditions according to the Maximum shear stress hypothesis and the Maximum strain energy hypothesis. Shaft diameter: 20 mm, Shaft Length 120 mm, F1 = 750N, F2 = 3000N, Mb = 2400 N.mm. Steel if St37 and Safety coefficient is 2 If taken, will this stick work safely under these operating conditions? (Yield of given steel Strength 225 Mpa, Tensile strength 370 Mpa)Two steel bars (Es = 200 GPa and αs = 11.7 × 10-6/°C) are used to reinforce a brass bar (Eb = 105 GPa and αb = 20.9 × 10-6/°C). When the steel bars were fabricated, the distance between the centers of the holes that were to fit on the pins was made 0.5 mm smaller than the 2 m needed. The steel bars were then placed in an oven to increase their length so that they would just fit on the pins. Following fabrication, the temperature in the steel bars dropped back to room temperature. Determine the maximum load P that may be applied to the brass bar if the allowable stress in the steel bars is 29 MPa and the allowable stress in the brass bar is 25 MPa.You are given a square rod of 6061-T6 aluminum (cross-section = 4mm X 4mm, length = 2.3m). The material has a Young’s modulus of 72 GPa. If a tensile load of 3 kN is applied parallel to the 2.3m dimension, what is the change in length of the rod?
