Can someone explain again what the "angled damage modifier" does. According to the news I just thought it will instantly drop the damage to zero, if you hit a tank in an angle between 60 to 90 degrees. But a few pages ago someone said the angle will also modify your damage, so you might survive shots, which penetrate and would have instakill you under a lower angle, but now does lower damge because of the angle.
See this diagram.
Let T be the thickness of armour and T
1 the effective thickness. Let A be the angle at which the shell hits the armour. A
1 or 90-A is the angle we're interested in, as it helps us to calculate T
1. Using basic trigonometry, sin A
1 = T / T
1 <=> T
1 = T / sin A
1. For example, a shell hitting a 60mm armour at 75 degree angle, we get T
1 = 60 / sin (90-75) = 232mm.
Actually, if the damage modifier is relative to the effective thickness, sin (90-angle) is all we need to know since that is the ratio; in this case, sin 15 = 0,259, meaning that 25,9% of damage is applied to the target.
