Strength defines how much you will hit. Attack defines how accurate you will hit.
That is, a higher attack will make sure you land more hits (instead of missing, i.e. hitting 0). A higher strength will make you hit higher values.
You can use this combat calculator to calculate your max hit. Also, this thread displays the combat formulas at code level.
Here is a copy of the formulas from the thread:
public static double combatFormula(int attack, int strength, int defence, int hitpoints, int prayer, int ranged, int magic, int summoning)
{
double combatLevel = (defence + hitpoints + Math.floor(prayer / 2) + Math.floor(summoning / 2)) * 0.25;
double warrior = (attack + strength) * 0.325;
double ranger = ranged * 0.4875;
double mage = magic * 0.4875;
return combatLevel + Math.max(warrior, Math.max(ranger, mage));
}
public static int meleeMaxHit(int strengthBase, int strengthCurrent, int strengthBonus, StrengthPrayers prayer, FightingStyles fightStyle, SpecialAttacks special, Effects effect, ItemSets itemSet, int hpBase, int hpCurrent, Websites website) throws Exception
{
// Check for invalid input

Standard Logout
After 5 minutes of non-combat inactivity, the game with automatically log you out.
Extensive Logout
After 6 hours, regardless of activity, the game will automatically log you out.
Combat Logout
After 20 minutes of inactivity while in combat, rather than logging you out, your character will stop automatically attacking the enemy. As a result, the enemy may lose aggression and eventually stop attacking you as well. Once the enemy loses aggression and stops attacking you, the standard idle timer will log you out.
If the enemies do not lose aggression, then you will remain logged despite exceeding the 20 minute mark. The Youtube video explains that he was able to stay logged in for over an hour while being inactive in the Nightmare zone because the enemies did not lose aggression and continued to attack.
