8541 Tactical

Since our S2 briefed us that this selected target is 5'8 (68) we can plug these figures into our formula. 68 inches tall times 27.77 (our constant) divided by the number of mils the target measured in the scope (4). Crank that through your calculator and you see that our target is 472 yards away. Now let's make this a little more difficult.

How to Calculate the Force of Friction

Down at the molecular level, when you press two surfaces together, minor imperfections in each surface can interlock, and there may be attractive forces between the molecules of one material and the other. These factors make it harder to move them past each other. You don't work at this level when you calculate the force of friction, though.
