8. Design Problem: A material is needed to support a hanging sculpture with an overall tensile load of 800 N. It is important that the material not undergo any permanent deformation under this load and must have minimum volume/diameter. Using a circular rod, design structural components using your data for each of the three materials. Which material would you choose for the application and why? If the requirement was minimum weight, rather than minimum volume, which material would you use? Show sample calculations.

The figure shown below (Fig. 2) is a schematic representation of a scissor jack in two different positions. The maximum load that this mechanism must withstand is 800 kg. 4 are proposed different materials to make the jack arms and spindle. The mechanical properties and some Physical characteristics of each material are shown in Table 1. a) Based on the properties of each material and the cross section of the arms and the screw, Propose what would be the most suitable material for its manufacture. The length of each arm is 150 mm. The stress on the arms and the spindle must not exceed the yield strength of the material selected for neither of the two analysis positions. b) Using the mechanical properties of the material you selected, calculate the change in dimension that the arms and the spindle of the jack were tested for the two analysis positions. The length of the spindle is 280 mm.
If a strengths-of-materials analysis determines the maximum torque that can be applied to a shaft is 1200 ft-lb, what is the power the shaft can deliver at 500 rpm? If the team says the shaft needs to deliver 150 hp, is the current shaft sufficient? If not, what maximum torque is required of the design team assuming the 500 rpm is a design constraint (i.e., to be held constant)? Q Search DELL 4 ESP

Imagine you are a Mechanical Materials Engineer working at Mazoon Electricals Company. You are assigned to select suitable material for the body of a three-pin electrical plug. Select a suitable material based on the design specification and selection criteria.
Turbine blades used in Jet engines can be made from materials such as nickel-based superalloys. Principle as such, ceramic materials such as zirconia or other alloys based on steel can even be used. In some cases, with a thermal barrier coating of blades to minimize exposure of Blade material to high temperatures it may also need to be coated. When selecting a material for the turbine blade and successfully in a turbine engine what design parameters do you consider for the coating that will work? Different parts of the engine are different please note that it is exposed to temperatures and not all blades are exposed to relatively high operating temperatures. What can such problems occur?

Suppose you're selecting materials for a frictional braking system which will be used to bring a moving body to a stop. It is imperative that you choose a braking surface material which will not thermally degrade as mechanical kinetic energy is converted to thermal energy during the braking process. You have a list of candidate materials for your braking system which includes maximum permissible average power dissipation. In order to relate average power dissipation rate to your system's mechanical properties (and select an appropriate material), what information will you need? mass of the body your braking system is decelerating maximum speed of your body at the time the braking system is applied duration of the braking process O all of the above
