Describe how the force components (Fx‚ Fy) change as the angle increases from 0° to 90° and use your graph to explain your answer. Give a detailed explanation of the forces at q = 0°‚ 45°‚ and 90°. Show a sample calculation at one angle for both components. Answer: The angle will determine how much force is exerted in horizontal direction and vertical direction. According the graph

The problem is believed to have been first introduced by Greek astronomer Ptolemy back in 150 AD1 and then eventually noticed by 17th century Arabic mathematician Abu Ali al Hassan ibn Alhaitham (whose name was later Latinized into Alhazen)2 .

ABSTRACT Design and construction of artificial infrastructure on the lines of biomimicking principles requires the development of highly advanced structural systems which has the qualities of aesthetic expression‚ structural efficiency and most importantly geometric versatility. Diagrids‚ the latest mutation of tubular structures‚ have an optimum combination of the above qualities. In this paper‚ the peculiarities of the Diagrid‚ its structural behavior under loading and the design and construction

We arrive at this by adding the two halves to the two full bends. To find the angle for each segment divide the angle of the bend 90° by three. This gives us 30°. So each full segment has a 30° angle and a ½ segment has a 15° angle. For construction we make an angle of 15° first or equating at C and draw the line from left to right. Next segment will be 15° + 30°. We then get the second segment by constructing an angle of 45°. The segment after that will be 45° + 30° = 75° leaving us with a 15° segment

Section 3.6 deals with the rotation of axes in two and three dimensions‚ including Eulerian angles and the rotation matrix of direction cosines. Finally‚ in section 3.7‚ a number of commonly encountered trigonometric formulas are gathered for reference. 3.2 Plane Triangles. This section is to serve as a brief reminder of how to solve a plane triangle
