HOW TO Transfer a position circle in chart work?
In transferring position you should measure your position or locate your position then bring it to the compass rose in order to get your position.
A painter is painting a mural on a wall. He has a 20-foot ladder. He needs to work on a part of the wall that is 16 feet above the ground. How far from the base of the building should he place the foo?
Using Pythagoras' theorem the the foot of the ladder should be 12 feet away from the base of the building.
What do you mean by build a ladder to reach the sky?
work hard to achieve high!
What is the formula for a 15 foot ladder is leaning against a 30foot wall the bottom end of the ladder is 9 feet from the wall how many feet above the ground does the ladder touch the wall?
If you take the trouble to draw a sketch of the situation that you've described, the method of solution, as well as the answer, will jump out at you. The ground, the wall, and the ladder, form a right triangle. The base is 9-ft, and the hypotenuse is 15-ft. If you've been assigned this problem as homework, then you've sat through enough geometry in class to know how to work with the right triangle. The length of the missing side is 12-ft, and it makes no difference how high the wall is, as long as it's high enough to support the upper end of the ladder.
How much power does a person weighing 500 N need to climb a 3 meter ladder in 5 seconds?
Work = 500 x 3 = 1,500 joulesPower = (work/time) = 1,500/5 = 300 watts = about 0.4 horsepower (rounded)
