Unit Conversion

Standard units are also called SI units. SI units are used for measuring a physical quantity satisfying certain conditions. There are two types of units: fundamental units and derived units. Fundamental units are physical quantities that are independent, that is, they do not depend on other quantities like mass, length, or time. There are plenty of quantities in our lives which need to be measured and compared. Measuring is the comparison of a particular physical quantity with its reference value. A unit is a measure of a fixed physical quantity. A physical quantity is the product of a unit and the numerical value we need to compare with.

Your team has been asked to design a steel beam bridge with 8m length as a simple supported beam (e.g. Figure 1, which is located in the Wollongong). The beam weight is 5kN considered as a distributed load over the beam length. In addition, in the worst case, two bushwalkers with 850N weight each will be on the bridge, they can pass the bridge together or individually. You only need to take the self-weight and pedestrian load into account in your calculations. Hint: you can consider two loads on the beam for each person or one load including the weight of both people. Determine the scenario that will create the maximum shear force and bending moment on the simply supported beam.

A proposed bridge across a stream is to be supported at the two ends and a central pier. To avoid damage, the settlement of the three supports must be similar and within certain allowances. Through computer modeling the estimated mean settlements and their standard deviations have been estimated to be: Support Mean Settlement (cm) Standard Deviation (cm) Left End 4.5 1.0 Center Pier 4.8 1.5 Right End 3.5 1.75 The maximum allowable settlement for each of the supports is 6.0 cm. For each support individually, determine the probability that the settlement will exceed this maximum allowable value. Show your work. Assuming that the three supports settle independently, what is the probability that all three settle more than the allowable amount? Show your work. Again, assuming that the supports settle independently, what is the probability that at least one of the supports settles more than the allowable amount? Show your work.
