(2013-2014‚ Semester 1) Laboratory Session 2 BRAZILE TEST XING BODONG 3035022904 Subclass Group C November 10‚ 2013 The University of Hong Kong Abstract The Brazil test is intended to measure the uniaxial tensile strength of prepared rock specimens indirectly. It is an indirect tensile testing of rock. The Brazil test provides an alternative to direct tensile testing‚ producing tensile failure in the end faces of cylindrical rock samples by subjecting these specimens

Physical fitness can improve not only body health but also mental health. Physical exercises improves muscle and strength but also strengthen bones and reduce body fat. Regular physical activity has always increased physical fitness. It is said that what affects our physical selves affects our psychological and emotional selves as well. Physical activity enhances both

The stress-strain diagram important for design engineers in that it establishes the physical properties of the material under test including the yield strength‚ the ultimate strength‚ the elongation at fracture‚ the elastic limit etc. Ductile materials‚ which includes structural steel‚ as well as many alloys of other metals‚ are characterized by their ability to yield at normal temperatures.[3] Materials that are

laminated materials fibre composites particle composites. A laminate contains thin pieces of material fused together. Common examples are plywood and car windscreens. Wood is durable when exposed to a ductile force equivalent to its grain‚ but if the strength is across the particle it splits simply. A windscreen is made in a parallel way; two sheets of reinforced glass are bonded to a piece of clear plastic in a sandwich. If the glass smashes‚ the plastic grasps the wrecked pieces together.

Answer. (b). Tube and pipe cross sections can be produced by either direct or indirect extrusion. 9- Which of the following stress or strength parameters is used in the computation of the force in an extrusion operation (one best answer): (a) average flow stress‚ (b) compression strength‚ (c) final flow stress‚ (d) tensile strength‚ (e) yield strength? Answer. (a). 10- In which of the following extrusion operation is friction a factor in determining the extrusion force (one best answer):

was tested three times using an Instron load frame and the BlueHill data acquisition software. The data from each test was used to determine valuable material properties such as ultimate tensile strength‚ modulus of elasticity‚ and yield strength. Other calculated properties included true fracture strength‚ percent reduction of area‚ and percent elongation. These material properties were used for comparing the materials to each other‚ and to define the material as brittle or ductile. The true stress

The Truth About A Quick First Step What is a First Step The first step is basically the first step you take of the dribble‚ when driving towards the basket‚ in order to beat your opponent to the hoop. It does take the right strength‚ coordination‚ and the right boost of energy‚ which is required from the leg you typically use to make your first step‚ but to become a better player‚ you should condition both legs to be able to take the first step when driving to the hoop. You will find that with the

Muscular Strength Muscular strength is the ability of a muscle or group of muscles to exert a force against a resistance in a single contraction. Strength is fundamental for all sports 3. Muscular Endurance Muscular endurance is the ability of a muscle to exert a force repeatedly over an extended period of time. 4. Flexibility
