textbook values of the steel sample. A sample of 7075 Aluminum was used in a cantilever beam test. Intermediate and end loads were place on the sample and the strain was measured at various distances from the loads. Using the dataset from the individual loads‚ the superposition strain was calculated and agreed within 7% of the experimental strain with both loads. From the measured deflection of the cantilever beam and the dataset‚ Young’s Modulus for the aluminum sample was determined to be 9.1x106

simple basic components and members of a building viz.‚ Slabs‚ Beams‚ Columns and Footings. In order to design them‚ it is important to first obtain the plan of the particular building that is‚ positioning of the particular rooms (Drawing room‚ bed room‚ kitchen toilet etc.) such that they serve their respective purpose and also suiting to the requirement and comfort of the inhabitants. Thereby depending on the suitability; plan layout of beams and the position of columns are fixed. Thereafter‚ the loads

associated with the experimental data. These uncertainties arise due to a random or systematic error. The uncertainties associated with a simple cantilever beam experiment‚ in which the deflection of the beam due to the applied load is recorded with both a dial gauge and a potentiometer. With the most suitable measurements of beam deflection the average value of young’s modulus and the uncertainties associated with that is calculated. The results were in accordance with the theoretical predictions

(SF) at any section of a beam represents the tendency for the portion of the beam on one side of the section to slide or shear laterally relative to the other portion. The diagram above shows a beam carrying loads W1‚ W2 and W3. It is simply supported at two points where the reactions are R1 and R2. Assume that the beam is divided into two parts bya section X-X. The resultant of the loads and reaction acting on the left of A-A is vertically upwards and since the whole beam is in equilibrium‚ the

Title: Deflection. Abstract: In this experiment‚ we were needed to find the deflection of Ring‚ Semicircle and quadrant made from the curved beam. The experiment is carry out by applied these beam with a load that weight 5N for circle and 2N for Semicircle and Quadrat. For the ring shape‚ the load is added 5N contiuosly until the load 40N and the dial reading is note down every time the load is added. Similar step is repeated using Semicircle and Quadrant that is we add 2N load continuously until

Aluminium using Cantilever loading Abstract The Young’s modulus of Aluminium was calculated using the measurements of the cantilever deflections. A beam of aluminium was clamped on one end and the other end was loaded with different weights‚ ranging from 1 to 15N. The deflection was then measured using a dial gauge. The slope of a load (abscissa) vs. deflection (ordinate) graph was then substituted into‚ E=4L3bd3(Slope). The Young’s modulus was calculated to be 67.3 GPa. The results were then
