PROBLEM EXERCISE - ASSIGNMENT The cross-sectional area of an aluminum bar is 160 mm? It carries an axial loads at the positions as shown in the figure. Compute the total deformation of the bar if E = 70 MPa. Assume the bar is suitably braced to prevent buckling. Draw the diagram and show your solution. Add the 2nd to the last digit of your i.d. number in the loads only. Ex: 202013178... 12+7=19, 16+7=23, 33+7=40, 30+7=37 19KN 16KN 33KN 30KN 1.0m 1.80m 0.70m

Quantity takeoff

Quantity takeoffs (QTO) are precise estimates of the materials and labor costs required to finish a construction project. During the pre-construction phase, an estimator prepares them, breaking down the project into smaller, more manageable parts that are easier to evaluate. These measurements are used to prepare a construction scope bid. Estimators examine the drawings, specifications, and models to figure out different quantities and their costs. Since, the components, their quantity, and price are all included in the model, quantity take-off can be done automatically using Building Information Modelling (BIM). The time taken for completing a construction project can be reduced by the use of quantity takeoff. These takeoffs are also called material takeoffs and construction takeoffs.
