Using the method of superposition, draw a neat labelled Bending Moment Diagram and Shear Force Diagram for the beam member shown in Figure 1, and determine the following:
(i) Bending stresses under maximum positive and negative bending moment;
(ii) Maximum nominal average shear stress;
(iii) Total deflection at the hinge B (theoretical result 0.035mm) and hinge D (theoretical result 3.3 5mm). Using approximate method only based on Figure 2.4 of your study book. Please clearly indicate your assumptions and comment on the difference between your results and theoretical results. Next year when you study CIV3 505 (structural analysis), you will learn more rigorous methods to determine the deflection, such as, Moment -Area Theorems and Conjugate-beam Method.
The beam segments are connected by pins at B and D. Assume that the beam is made of steel (250UB31.4) with E=200x10^3 MPa and is loaded in its strong axis direction.
The following data represents, in square meters, the cross-sectional areas along a short portion of highway. Calculate the net volume of earthworks needed or available over the portion of the highway. Draw the Mass-Haul-Diagram for this project.
A gun is aimed at point A located 15 degrees N or W. Knowing the gun forms and angle of 25 degrees with the horizontal and the max recoil force is 400 N, determine a) the x, y,z components of that force b)
A factory emits 70 g/s of NO2 from an effective stack height of 40 m. The wind speed is 5.5 m/s and it's a cloudy night. There is an atmospheric inversion at an elevation of 100 m.
Under these conditions flow is expected to be turbulent, but for a clean air, very smooth enterance (with guided vanes) to the tube and no tube vibration, it may be possible to maintain laminar flow.
Because of the insulation between them, the sun heats up the wall panel 120 degrees F but the column to 80 degrees F. Determine the consequent compressive stress in the curtain wall.
Write a MATLAB program that loads the sensor_new.dat file. The sensor readings were actually taken every second over a period from 0 to 19 seconds. Create a time vector going from 0 to 19 in 1 second increments.
Give one possible characteristic or property of sanstone and of the quartzite that made you decide not to select it for your concrete project?
Briefly explain the difference between piezometer and tensiometer with respect to the working principle, special design consideration and limitation of the instrument.
A 60 -m- long steel wire must not strech more than 48mm when the tension in the wire is 6 kn. Knowing that e-200GPa, determine (a)the smallestdiameter which may selected for the wire,(b)the corresponding value of the normal stress.
Two pounds of an ideal gas are contained within a piston-cylinder arrangement. The initial volume and pressure are 1 ft3 and 75 psia respectively. The final volume is 3 ft3.
Knowing the submerged depth of each of the 5 pressure taps and the density of water, determine the calculated pressure at each of the 5 pressure taps.
For an unknown alloy the stress at which plastic deformation begins is 400MPa and the modulus of elasticity is 120GPa. If the original specimen length is 76 mm
