In conclusion, Newton’s laws of motion have influenced the design of wings as they are required to produce lift, so the wings must be suitable for them to apply. The flaps and slats allow to maintain lift at slow speeds by increasing the wing area and curvature ,using force equals mass times acceleration ,and the first law allows the plane to maintain a constant speed in air. Other factors that influence the design of wings is the purpose of the craft focusing on manoeuvrability or comfort and efficiency determining the material and size of the wings. The changes in the design and materials used is also due to the availability of better resources such as alloys today which are more resistive and less dense since the wings must be able to withstand the arching and weaving during flights. For example, the first successful flight was achieved by the Wright brothers whom had an aircraft with wings made up of wood, currently most aircraft have wings made from aluminium and or titanium alloys since they are very resistive and low density materials. For a plane to travel at a desired speed without requiring much engine force of thrust the mass must be very small since acceleration equals force divided by mass, hence why light weight materials are preferred.
In conclusion, gender equality is a human right, but these days our world faces with a continuous gap in approach to opportunities and higher cognitive process power for women and men. It is important to notice that the main issue of the gender disparity is that generally, women have the fewer ability for economic participation than men, less selection of basic and high education, high health and safety risks, and less political representation.
Also, one of the main issues which makes social downside is the education, is the major point of focus. Though the world is creating progress in achieving gender parity in education, the girls still on a high percentage of not attending school children than boys. So, overall, we can say that around one-quarter of girls within the progressing world do not attend school. Typically, families with limited potentialities who cannot provide expenses such as, school fees, uniforms, and supplies for all their kids will prioritize for their sons. That means families can rely on girls for housework, carrying water, childcare, by leaving them restricted time for education. All in all, an educated woman have more possibilities to postpone marriage, raise a smaller family, have healthier and also educated children. Furthermore, she has more opportunities to earn more financial gain and to attend in political processes.
Finally, let’s sum up recommendations of social action.
Girls and women will feel safe when they are free from sexual and gender-based violence.
The world have to improve health systems that supports girls and women rights to health throughout their lives, contribute safe, healthy and operating societies, and economic growth and development.
Girls and women has to be heard, engaged and guide on an equal footing with men in all sectors.
