Consider a study to determine the compressive strength of concrete blocks used for paving Two methods of manufacturing concrete blocks are under investigation-method 1 (which is more expensive) and method 2. Research indicates that the greater the compressive strength of concrete, the greater the durability of a concrete block. Therefore the question is which if either, of the two methods produces greater compressive strength. In addition, the manufacturer considers that an average difference between the methods of less than 500...

326 СНАРТER 6 BENDING EXAMPLE 6.18 The reinforced concrete beam has the cross-sectional area shown in Fig. 6-39a. If it is subjected to a bending moment of M = 60 kip ft determine the normal stress in each of the steel reinforcing rods and the maximum normal stress in the concrete. Take Est = 29(10) ksi and Econc = 3.6(103) ksi SOLUTION Since the beam is made of concrete, in the following analysis we will neglect its strength in supporting...

Assignment Details Aluminium alloys are very widely used in the industry as structural metals, second only to steel. Pure aluminium is very soft, light in weight and low melting point which makes it quite popular for various applications. However, adding alloying elements to aluminium enhances various physical properties making it even stronger and versatile for numerous engineering applications. Answer the following questions 1. Identify the following information for pure aluminium: Atomic number Atomic mass Atomic radius Crystal structure Density Periodic...

A material may fail in many ways; in a ductile or brittle mode; by creep or fatigue; by corrosion or stress corrosion; by hydrogen or liquid metal embrittlement; by slow tensile overload or by impact. An examination of the failure may tell you a lot about the material and the failure mode. In this course, you...

"Annexure B" ASSIGNMENT 2 DESIGN BRIEF Due to increasing pedestrian traffic of students travelling from halls of residence to the engineering block at one of its devised a plan, which includes a new means of crossing a busy road safely and without causing traffic delay. A solution to protect student safety for crossing the busy road is to design and build a pedestrian bridge. This will eliminate traffic congestion and delays as well as eliminate conflict between pedestrians and motorists....
