Effect of Sun angle on climate sunlight shines on the earth at a lower angle (Sun closer to the horizon), the energy of the sunlight is spread over a larger area, and is therefore weaker than if the Sun is higher overhead and the energy is concentrated on a smaller area. Figure 2 depicts a sunbeam one mile (1.6 km) wide falling on the ground from directly overhead, and another hitting the ground at a 30° angle. Trigonometry tells us that the sine of a 30° angle is 1/2, whereas the sine of a 90° angle is 1. Therefore, the sunbeam hitting the ground at a
Type 10 concluded that there was not enough internal space for a C4I system upgrade on existing tanks. Therefore, the development of a new main battle tank capable of various future battle missions was necessary. The use of modular components significantly improved the side armor compared to the Type 90. The Commander's Panoramic Sight was moved to the right and is located at a higher position than the Type 90, giving the commander a wide range of view. The vehicle's armor consists of modular sections, providing the ability to mount varying degrees of protection depending on the mission profile and weight requirements.
