Question

Commercial hose connectors used for watering and irrigation are sold in variety of sizes and shapes. The cost of such connector depends on the cost of material from which it is made and some other design limitations. Using the following information:

Tensile load imposed on the connector is 20,000 N. Deformation of the connector is purely elastic. Outer diameter (OD) of the connector is 20 mm. Length of the connector is 30 mm. Inner diameter (ID) of the connector is 10 mm. Safety factor, N = 2. The maximum connector elongation is 1.5 x 10^-2   mm                                            

   Answer the following question: What is the value of minimum Modulus of Elasticity? Round off your answer to four significant figures. Do not include the units.
