trigonometric relationshipsBackground We talked in class about the use of trigonometric relationships to define the angle between lines. In this lab we will usethose basic concepts to develop a tool that will allow you to estimate the heights of large objects. The basic concept is shown inthe figure. If we can establish the two lines, then the ratios of the sides will always be same. So, if what we’re trying to do isfind the height B, if we know the ratio b/a and the length A, then B = A * (b/a). For example, if b is 1/10 a (so b/a = 1/10) and A= 50 ft, then B = 50 ft * (1/10) = 5 ft. This is most easily thought of in terms of ratios, where the ratio b/a means that we have 0.1

Table 1.Another interesting finding was that the students who were predicted to do well in the 10 am and2 pm classes (i.e. receive a final grade of A or B) but did not receive intervention techniques, didnot perform as well as originally anticipated as a group. In the 10 am class the predicted average Page 3.81.2of at-risk students was 1.581, while their actual average at the end of the course was 2.186.Intervention resulted in a positive difference of 0.605. However, the non-intervention group wasanticipated to have a final average of 3.429, but only achieved an average of 3.086. Similarresults occurred in the 2 pm class are shown in Table 2

Invariably there are two main problems that are encountered: a)With the dwindling financial resources, the submitted proposal has to “compete” with severalothers from the department, college, and sometimes from the whole university forconsideration in terms of urgency of the need for replacement, and (this is the bottom-line) thecost. The “canned experiments and packages” are usually very expensive. Therefore, the moreexpensive equipment is the lower the priority a request receives. b) The equipment may notallow sufficient flexibility for a more detailed

. Those planning to participate for multiple yearshad to judiciously select the number of credit hours they wanted to commit to. Student gradeswere determined based on the number of hours they worked and the credit hours they signed upfor. Assuming a student should spend two hour out of class for every hour in class, one creditrequired a commitment of 30 hours to earn an A grade. Other grades were based on a linear ratioof time worked (B = 27 hours, C = 24 hours, etc.). Not all students received an A.The university students were placed in a unique position as mentors to the high school studentsand mentorees for the engineers. As mentors they were invaluable in making the high schoolstudents feel like contributors to the overall project. This lead

This sectionwould normally be longer than the background and should be integrated with the backgroundinformation. Several forms for presenting the problem can be used. Examples of form are: a)multiple parts meaning a cross-discipline approach, b) technical narrative to support questions,and/or c) open-ended statements.The questions are to stimulate the student’s critical thinking processes.

Inaxisymmetric elements the hoop strain Hr is not constant; it is a function of 1/r that varies withradial position in the element. For this reason, B contains 1/r terms, as does the BT D B rproduct.Prior to proceeding further with the
