Chapter 7 - Essay Example while being ensured no negative consequences are to occur. Climate for excellence can be real or a superficial facade to hide the lack of innovation. Support for innovation means backing innovative ideas with practical help. Innovation is fostered and/or hindered by the organizational management and the attitude thereof. However, it is good to remember that vision, consistency and articulate argument makes even minority groups (work groups in huge organizations are minority groups) effect change. Minorities need to be (or at least appear to be) autonomous and not working in opposition to the group’s interest. It is good to remember that resistance would be faced, and should be expected. Characteristics of innovative teams, which are actually in the minority include: clear vision, everyone should have the same vision and goal; communication, it needs to be adequate and consistent as assumptions need to be cleared out too; flexibility, willing to listen to others outside the tea m as well, especially when the team’s own ideas are being presented to them; persistence, adaptability does not mean abandoning ideas; participation, include as many people in the team as possible.

Photoelastic Methods Assignment Example | Topics and Well Written Essays - 1250 words

Photoelastic Methods - Assignment Example There has been recent methods namely Converging Light Method, Scattered Light Method and freezing Method, which are used in direct application of three dimensional models. In the engineering field, this method of photoelasttic analysis of stress is important as it is used to calculate stresses under different circumstances. A series polariscope involves an optical instrument that is used in performing the measurements of quantitative strain through photostress reflection photoelasticity method. The device is lightweight and compact and easy to operate. It is always designed for the tripod mounting or hand hold. It is always equipped to accommodate different special purpose accessories that adapt it to perform different tasks of measuring the strain with the photoelastic coatings. This experiment was conducted with a view to apply the photoelastic methods of measuring stress to get the values of the normal stress values of a beam and making a comparison of the measured stress values computed from the theory of elementary material strength. The study sought to compare theoretical values with measured values of the beam deflection. This study also sought to demonstrate the use and application of Maxwell’s law of reciprocal deflections In this experiment, the focus was on beam analysis. It involved applying the photoelastic techniques, and testing the cantilever beam. The aim was to use the Cantilever beam to help understand the fringe by relating to the magnitude of strain. As often the case, the cantilever beam is always coated at one end using a photostress plastic and clamped to the table’s or bench’s edge. Besides, the sought to measure the deflection using the dial gage and the stress found by photoelasticity. The beam dimensions were taken and mounted to the needed fixed support with the help of a C clamp. A single dialing indicator was put at the beam’s center and the other next to the free end
