What is the formula of area of a rod in length and radius?
The formula for the area of a rod, which is a cylinder, is given by A = 2πrh + 2πr^2, where A is the total surface area, r is the radius of the rod, and h is the length of the rod. The first term 2πrh represents the lateral surface area of the cylinder, which is the curved surface area, and the second term 2πr^2 represents the area of the two circular bases of the cylinder. By summing these two terms, we obtain the total surface area of the rod.

What would the final length of an aluminum rod that measures 7.5 feet if the temperature rose from 25 degrees to 125 degrees?
To calculate the final length of the aluminum rod due to thermal expansion, we use the formula: ΔL = L₀ * α * ΔT, where ΔL is the change in length, L₀ is the original length, α is the coefficient of linear expansion for aluminum (approximately 22 x 10⁻⁶ /°C), and ΔT is the change in temperature. The temperature change (ΔT) from 25°C to 125°C is 100°C. Thus, the change in length is ΔL = 7.5 ft * (22 x 10⁻⁶ /°C) * 100°C, which results in an increase of approximately 0.0165 feet. Therefore, the final length of the rod would be approximately 7.5165 feet.
How long must the brace be on a closet rod holder if the vertical side is 7 cm and the horizontal side must be attached 30 cm from the wall?
Pythagoras! length = sqrt (7 squared + 30 squared) ie sqrt 949 ie 30.81 cm
Why is aluminum difficult to weld?
Aluminum is a bit more difficult to weld than steel , because of it's lower melting point. Also Aluminum takes more heat , because of it's property of absorbing and releasing the heat quicker. With the proper electrode , or rod , and amps to volt settings, along with a bit of practise , it can be quite simple . One usually has to have a faster travel speed with the filler rod or electrode.
What is the volume of a rod?
The volume of a rod can be calculated using the formula for the volume of a cylinder, which is V = πr^2h, where r is the radius of the rod and h is the height (or length) of the rod. If the rod has a constant cross-sectional area, the volume can also be calculated by multiplying the cross-sectional area by the length of the rod. The unit of measurement for the volume of a rod would be cubic units, such as cubic inches or cubic centimeters.
How much does a 8 feet long 3 inch diameter steel rod weigh?
The weight of a steel rod can be calculated using the formula: weight = volume × density. The volume of a cylinder is given by the formula ( V = \pi r^2 h ), where ( r ) is the radius and ( h ) is the height. For an 8-foot long rod with a 3-inch diameter, the radius is 1.5 inches (0.125 feet). Using the density of steel, which is approximately 490 pounds per cubic foot, the rod weighs about 24.5 pounds.

What is the weight of a steel rod whose dimensions are 25mm diameter and 3050mm long?
To calculate the weight of the steel rod, you first need to find the volume using the formula for the volume of a cylinder (V = πr^2h, where r is the radius and h is the height). Then, you can calculate the weight by multiplying the volume by the density of steel, typically around 7850 kg/m^3. Finally, convert the volume into meters before calculating the weight to ensure consistent units.
Does rod have a long or short o?
The word rod has a short O sound, as in rob and god. (The long O is in road.)
Formula to find weight of a steel rod whose dimension are 8mm diameter 1meter length?
You look up the density of steel, then calculate the volume of the rod, then multiply the density by the volume to find the mass of the rod. To find the weight of the rod, you multiply it's mass by gravataional acceleration.The rod has a cross sectional area of Pi x (0.008 / 2)2 m2Volume of the rod = 1 x 5.027x10-5Steel has a density of approx. 7850 kg/m3.Mass = Density x VolumeMass = 7850 x 5.027x10-5Mass = 0.395 kgWeight = 0.398 x 9.81Weight = 3.871 Newtons
How do you calculate the weight of aluminum rod in inches?
To calculate the weight of an aluminum rod in inches, you would need to know the density of aluminum (which is about 0.098 lbs/in^3) and the volume of the rod (which can be calculated using its length and diameter). You can then multiply the volume by the density to find the weight of the aluminum rod.
How do you measure rest volume in a oiltank?
It is best if u know the diameter or the circumference. then u can dip a rod into it and see the height of the oil on the rod after removing it. calculate the volume of cylinder as u know the parameters. offcourse do a bit work to find the formula its easy. it this is NT possible see the holding capacity of the tank. and dip the rod again see the level. its gives estimated but useful information and prevents ypur vehicle from getting out of fuel!!!
What is formula for calculate the weight of round brass rod?
First, you need to know the mass of brass: Brass, Specific Gravity 8.56 lb per Cubic Foot (from wikianswers) second: you need to know the length and radius of the rod. formula: divide the radius of the rod by two square the answer you get (multiply it by itself) multiply by pi You have now calculate the area of the rod's end. multiply the answer by the length of the rod and you get the volume of the rod finally, multiply the answer by the specific gravity for brass. The answer is the weight of the brass rod NOTE: make sure you use the same units for length and mass throughout the formula. In the above example you will have to know the radius and length in feet to yield the weight in lbs. If you want to know the answer in a different unit (ounces for example) you will have to convert the specific gravity to correct units.
