2. The uniform bar has a mass per unit length of 60 kg/m. Determine the reactions at the supports. Ans. Ay = 3060 N‚ By = 2060 N. 3. The uniform angle bar with equal legs has a mass of 20 kg and is supported in the vertical plane as shown. Calculate the force FA supported by the pin at A. Ans. FA = 277 N. 4. Determine the reactions at A and E if P=500 N. What is the maximum value that P may have for static equilibrium? Neglect the weight of the structure compared

VIBRATION - I Aim: To find the natural frequency of transverse vibration of the cantilever beam. Apparatus required: Displacement measuring system (strain gauge) and Weights Description: Strain gauge is bound on the beam in the form of a bridge. One end of the beam is fixed and the other end is hanging free for keeping the weights to find the natural frequency while applying the load on the beam. This displacement causes strain gauge bridge to give the output in milli-volts. Reading of the

Stiffness Report from laboratory work performed on 12 May 2011 as a part of the unit of study CIVL2201 Structural Mechanics Abstract This report has been written to describe an experiment performed on a channel section examining the stiffness of the beam through two differing types of deformation – curvature and deflection. The aim of the experiment was to determine the value of the flexural rigidity (EI) in two different ways; using the curvature‚ k‚ and the mid-span deflection. The testing method

drilled through ceramic substrate to release the THz wave‚ the THz amplitude of entire interdigital antenna array with 8 antenna units can be more than 10 times larger than that of resonant dipole antenna. To get this result‚ the pump beam is focused into a linear beam by a cylindrical lens to trigger the antenna array‚ and the linear THz wave is focused by a polyethylene lens before it reaches ZnTe crystal.

functions that bridges have are: Aqueduct: They are used for water conveyance. Viaducts: They are built to have automobile transit. Footbridges: Built for the use of pedestrians only. The way bridges resist their efforts: Beam: They consist of horizontal elements that are supported at their ends on supports or pillars. The force transmitted through the pillar is vertically downwards and‚ therefore‚ they are subjected to
