Thermal Properties of Materials

In mechanical engineering, the thermal property is represented as the physical quantity that is relevant to the application of heat. The thermal properties are evaluated by variations in any specific material due to low heat or high heat. The quantities that influence the thermal property of the materials are mass, density, temperature, and many others.

Required information A solid square rod is cantilevered at one end. The rod is 0.6 m long and supports a completely reversing transverse load at the other end of ±1.7 kN. The material is AISI 1080 hot-rolled steel. If the rod must support this load for 5 x 104 cycles with a design factor of 1.5, what dimension should the square cross section have? Neglect any stress concentrations at the support end. What will the strength of the metal be at 5 x 104 cycles? The strength of the metal at 5 x 104 will be MPa.
Design of Machine Elements Assume you have a 30 mm in diameter AISI 1040 steel shaft welded on a rigid surface. Forces appliedto this shaft is given below. What would be length of the shaft considering the conditions as givenbelow;− 40 Nm torque is applied throughout the shaft (torque)− 100 kg load is applied at the end point of the shaft (bending)− 250 kg load is applied to push the shaft in the compression direction (normal force)− Factor of safety should be 2

Design a helical compression spring for a maximum load of 1000 N for a deflection of 25 mm using the value of spring index as 5. The operating load is considered as average load service. Choose a suitable material from table (23.1) for your design. If the same helical compression spring that was designed in Q1, is subjected to a load which vary from 200 N to 600 N. Based on the new condition, will the spring endure the new load? Consider that the allowable shear stress in table (23.1) is the yield stress and the endurance shear stress is 0.8 to 0.9 of the yield in shear. mechanical desgin pls solve fast
