In order to reach a roof that's located 24 feet above the ground the ladder used must extend to a height of at least?
Assuming it is a two section ladder then it must therefore have a minimum length of 28 feet.
What happens to voltage when wire length increase?
When the length of the wire increases voltage drop across the wire will occur.There are two factors that can result in voltage drop. One diameter of the wire, two length of the wire.Voltage drop increases with increase in length of wire, whereas voltage drop decreases with increase in diameter (cross section area) of the wire.G.RAOAnswerIf you are asking what happens to the voltage across a length of wire when its length increases, the answer is nothinghappens! The voltage applied to the wire is determined by the supply, not by the load (i.e. the wire).
How do you work out resistance with voltage and joules?
Resistance of a conductor is defined by the specific resistivity, area of cross section and the length of the conductor. R = rL/A, where R is resistance in OHMs, r is specific resistance, L length in mm, A is area of cross section in sq mm
What are mathematical relationship between resistance and specificconductivity constant?
Cell constant(C) = Resistance(R) X Specific Conductivity(K)
What is slenderness ratio structural engineering?
The slenderness ratio is the ratio between the height or length of a structural element (such as a column, or strut) and the width or thickness of the element. For example, if a rectangular column is 6m high, and 400mm by 600mm in cross-section, then its slenderness is 6000/600 = 10 in one direction and 6000/400 = 15 in the other direction. The higher the slenderness ratio, the more slender the structural element is. How slender a structural element is allowed to be depends upon the material it is made from. Steel can be more slender than concrete, for example. In structural engineering calculations, the slenderness is often denoted as the element's "effective" length divided by something called the radius of gyration. The radius of gyration is a measure of the average distance of the material from the centroid (centre of gravity) of the element's cross section. This can be calculated as r = (I/A)0.5, where I is the second moment of area, or second moment or inertia, of the cross section and A is the area of the cross section. The effective length of an element is determined by how it is fixed at its ends. The effective length is the length of the column that will form half a sine wave if it buckles. If it is "pinned", or has hinged ends, the effective length is the true length of the element. If it is a cantilever (fixed at one end but free at the other), the effective length is twice the true length. If it is fully fixed at both ends the effective length is 0.7 times the true length, but this is in reality very difficult to achieve, so often a real structural element is considered to be only nominally fixed and the effective length is taken to be 0.85 times the true length.

Assuming it is a two section ladder then it must therefore have a minimum length of 28 feet.
The base of a ladder is 7 feet away from the wall The top of the ladder is 19 feet from the floor Find the length of the ladder to the nearest thousandth?
Using Pythagoras' theorem the length of the ladder is 20.248 feet
What ladder type offers the greatest length in general purpose ladders?
Extension Ladder
A ladder is leaning against a building so that the distance from the ground to the top of the ladder is one foot less than the length of the ladder. Find the length of the ladder if the distance from the bottom of the ladder to the building is 5 feet?
A. 11 feet B. 13 C. 12 D. 14.
Are step ladder heights measured to top rung or the platform?
The length of a step ladder is its height. An eight foot step ladder is 8' long.
A ladder is resting against a wall The top of the ladder touches the wall at a height of 6 feet Find the length of the ladder if the length is 2 feet more than its distance from the wall?
10 feet, and it is at a very dangerous angle.
A log is 2500 cm in lengthhow many meters is itthe diameter cross section measures 250 cm?
The diameter of a log cannot be determined from its length.
A ladder is resting against a wall the top of the ladder touches the wall at a height of 18 feet find the length of the ladder if the length is 6 feet more than its distance from th wall?
24
A ladder of length 5m rests against a wall The foot of the ladder is 1.7m from the base of the wall How far up the wall does the ladder reach?
6.7
What is 4 to 1 ratio for ladder use?
That probably refers to the ratio between the length of the ladder, and the distance at which you place the bottom part of the ladder from the wall. If this distance is too short, you have the risk of the ladder falling backwards.
What is the formula for the length of a square?
The length of a square is not determined by a formula, it is determined by measuring the square.
