If h is vertical height, b=horizontal distance from wall to bottom of ladder and l=lenght of ladder,we can say lsquared = hsquared + b squared. Now differentiate w.r.t. time t. 2l*dl/dt= 2h* dh/dt + 2b*db/dt =0 However this solution doesn't give exactly the same answer when one solves the problem geometrically or using simple pythagorus. For example ,if l=20m and b=12 m and h=16m and db/dt is 2m/s, I calculate dh/dt as !.5 m/s using calculus but 1.717 m/s using geometry or straight Pythagorus. Where is the fallasy inthe method using calculus? Ray Bevan
Rule one is to never believe anything unless you know it to be true. Rules two is to divide any issue into as many parts as possible for examination. Rule three is to find the easiest solution and work up to the most difficult. Rule four is to list every possible detail of a problem.
A roof ladder or an extension ladder can be used for accessing the roof of one's home. One should take precautions when using a roof ladder to ensure safety. One should position the ladder so the bottom of the ladder is away from the wall one foot for every four feet in height it will be raised. The top of the ladder should be extended no more than four feet above the roof line. One should keep their body in the center of the rungs as they climb the ladder.
Ladder SafetyMake sure that your ladder is sturdy.Make sure the ladder is on level ground and secure.The ladder should be opened completely and locked in place.When using a ladder outdoors, make sure the location is away from power lines.When using extension ladders, use the 4-to-1 rule. For each four feet of distance between the ground and upper point of contact (such as the wall or roof) move the base of the ladder out one foot.When climbing the ladder, always face the ladder.Shoes should have slip resistant soles, such as rubber soles.Gauge your safety on a ladder by your belt buckle. Center your body on the ladder and if your buckle goes beyond the ladder's rail you can risk falling due to over reaching.Rungs should always be dry when using a ladder.On a step ladder, the second rung from the top is the highest safe level you should use. For an extension ladder, the fourth rung from the top is the highest safe level you should use (check with the manufacturers recommendations for your particular ladder).

By giving your employees the right OSHA, WHMIS or Hazwoper course, they will be educated with all of the safety rules and safety symbols they may encounter at their work.
The best tip I've come to is that for every four feet of height you have to climb, move the base one foot away from the wall. Better still is to have someone foot the ladder, or to fasten the ladder with a rope, preferably near the top of the ladder to avoid the ladder sliding sideways.
Five. One to hold the lightbulb and four to turn the ladder.
Aristotle put it as being: Monarchy (rule by one), which degraded to Tyranny (rule by one dictator). Aristocracy (rule by the best people), which degraded to Oligarchy (rule by the few). Democracy (people power), which degraded to Ochlocracy (mob rule). Not four there - six.
