Polytechnic University Department of Civil & Structural Engineering BEng(Hons) in Civil Engineering Structural Mechanics II Laboratory Instruction Sheet: Unsymmetrical Bending Objective: To observe the two principal axes in a beam with unsymmetric cross sections; and make comparison between the theoretical and actual behavior in bending of two unsymmetrical section cantilevers: 1. An equal angle with one axis of symmetry. 2. A Z section completely unsymmetrical. Apparatus: Vertical cantilever system

1. Characteristic Loads-Characteristics‚ Importance‚ Applications Actions By E.C. An action (F) is a force (load) applied to the structure (direct action ) or an imposed deformation ( indirect action ) ex. Temperature effects. Actions are classified: a) by variation in time permanent actions G ( self-weight of structure). b) by their spatial variations: fixed actions ( self weight ) variable actions Q wind loads/snow. free actions which results in different actions accidental actions

the shear strength of the glued joint controls the design‚ what axial force P is to be applied to the member to get separated to 2 parts? Assume the shear strength of the glued joint to be 10MPa. Fig: 1 (b) An exploded view of a bolted connection is as shown in Fig 2(b). The width of the plate is 60mm; their thicknesses are t1 =10mm. The snugly fitting bolt is 20mm in diameter. Calculate the maximum normal stress in the plates at the critical section due to an applied tensile force P=70 kN

II (Winter 2013) Experiment 2: Bending of an aluminum I-beam Introduction “Beams are long straight members that are subjected to loads perpendicular to their longitudinal axis and are classified according to the way they are supported”[1]. When a beam is subjected to an external load there are unseen internal forces within the beam that one must be aware of when implementing it into any design or structure. These internal forces create stress and strain

SureCut Shears‚ Inc. is a manufacturer of household scissors and industrial shears. Because of a policy of level production and a seasonal sales pattern‚ the company has to borrow funds under a line of credit to cover its seasonal buildup in inventory and receivables. During 1995-96‚ sales began to fall from projected levels due to a retailing downturn. However‚ the company may have been slow to react resulting in an accumulation of excess inventory and related inability to repay its bank loan prior

Blue Ocean Strategy: FROM THEORY TO PRACTICE W. Chan Kim Renée Mauborgne F or twenty-five years‚ competition has been at the heart of corporate strategy. Today‚ one can hardly speak of strategy without involving the language of competition: competitive strategy‚ competitive benchmarking‚ building competitive advantages‚ and beating the competition. Such focus on the competition traces back to corporate strategy’s roots in military strategy. The very language of corporate strategy is

Report Beam Bending and Superposition Author Tutor Prof. Menary Semester 1 Date 28/11/2011 Summary An investigation into beam bending and superposition. Being able to analyse how beams bend is an essential tool for all engineers. By using mathematics and material properties‚ engineers are able to compute structural deformation thus verifying a structures fitness for use. In this experiment a simply supported beam of aluminium is loaded with point forces in three different

What factors affect the bending of bridges? Abstract: This experiment was designed and conducted to find out how different factors affect the amount of bending of the beam. The two variables that were tested were the amounts of weight and the position of the weight on the plank. Aim: To find out how weight and different placements of the weight affect the bending of the beam. Hypothesis: It is predicted that the wood will bend more if there is more weight on it. When the weight is positioned
