What’s the second rule in driving?
The 2-second rule is a technique used to estimate a safe following distance between your vehicle and the traffic ahead.

If they reach two seconds before reaching the reference marker they need to drop back. The picture below shows how intimidating it can be when someone is driving too close.
What are the three basic elements of a gear?
Module (m) , Pressure Angle (α) , and the Number of Teeth, introduced here, are the three basic elements in the composition of a gear. Dimensions of gears are calculated based on these elements. Tooth Depth and Thickness. Tooth depth is determined from the size of the module (m).
What is a gear module?
The ‘module’ system is widely used all over the world to conveniently designate sizes of gear teeth. Here, we will explain the definition of the module. TEL : +81 48 254 1744
What are the sizes of gear teeth using the module system?
The sizes of gear teeth using the module system are indicated with the symbol m followed by numerals such as m1, m2, and m4 where the teeth sizes get larger as the numerical value increases. Figure 1 – The comparison of teeth sizes between Module 1.5 (left) and module 4 (right)
What is the crossing angle of the test gears?
The test gears are beveloid gears with parallel axes. Thus, the crossing angle is Σ = 0°. Furthermore, due to the setup of the test rig, the center distance amounts to a = 91,5 mm. In total, eight different gear variants are examined. For all gear variants, the normal module is m n = 2 mm and the profile angle is α n = 20°.
