b. The strong room where AIT exam question papers are kept is made up of rectangular metal bars. One bar has a width of 10 mm and would be able to withstand a maximum compressive stress of 20 MPa. i. Prove that, the minimum breadth of this bar can withstand a burdened with a force of 3 KN. ii. If the bar in question is 2 m long and decreases in length by 0.25 mm when a force is applied, then show that a percentage strain can be obtained. iii. What would be its Modulus of Elasticity, E?

Assignment 1 A 175-lb woman stands on a vinyl floor wearing stiletto high-heel shoes. If the heel has the dimensions shown, determine the average normal stress she exerts on the floor and compare it with the average normal stress developed when a man having the same weight is wearing flat-heeled shoes. Assume the load is applied slowly, so that dynamic effects can be ignored. Also, assume the entire weight is supported only by the heel of one shoe. 1.2 in. 0.5 in. MR.

QUESTION 4 4.2 4.1 The ratio between the outside diameter and inside diameter of a pipe is 2,5 and the length is 400 mm, when the pipe is not subjected to any load. When a tensile load of 200 kN is applied to the pipe, its length increases by 0,195 mm. The Young's modulus of elasticity for a pipe is 188 GPa. Calculate the inside diameter and outside diameter of a pipe. The following results were obtained by means of a tensile test on a carbon steel specimen, having an original cross-sectional area of 20 mm² and the gauge length is 50 mm. Elastic limit load: Elongation at the elastic limit: =0,06125 mm =4 900 N Maximum load: =7 650 N Load at fracture: =5 050 N Elongation at failure: =15,2 mm Cross-section area at failure: 7,95 mm² Calculate the following: 4.2.1 The stress at the elastic limit. 4.2.2 The maximum stress. 4.2.3 The percentage elongation. 4.2.4 The percentage reduction in area.
