Find the second moment of area about the vertical axis for the cross-section of the follwing shape. i can't get the pic to paste so will describe it: it is a rectangle of horizontal length 8 and vertical height 6. if we let (0,0) be at the lhs bottom corne...
Use a micrometer to measure the original length (L0) of the material you’re working with, but do this before any force is applied or stretching occurs so that you can get the most accurate answer. 2. Use the Micrometer to Measure the Cross-Sectional Area and Other Diameters Measure the...
To test the strength of materials, an instrument pulls on the ends of a sample with greater and greater force and measures the resulting change in length, sometimes until the sample breaks. The sample's cross-sectional area must be defined and known, allowing the calculation of stress from th...
Figure 1: The light guide in this example is a mixing rod that you might find in a projector. The light guide is used to homogenize the light coming from a traditional light source and reflector. At the input side, light peaks sharply in the center; at the output side, light is spatia...
What is a cross-sectional area of a bridge, and does it affect the length of a bridge? Suppose that a steel bridge, 1000 m long, was built without any expansion joints. Suppose that only one end of the bridge was held fixed. What would the diffe...
Strength is directly related to the size (that is, the cross-sectional area) of the muscle. Muscle fibers are capable of developing a maximal force of 3 to 4 kg/cm2 (average = 3.5 kg/cm2) of muscle area. So, let's say that you have increased your muscle size from 100 to 150 ...
But the surface of Mars looks like a dry, inhospitable desert. Today, Mars has no lakes, no rivers, and no rainfall. So where will we get our water from? We spoke to three experts to find out. This article is part of Life On Mars – a 10-part series that explores the cu...
In other words, the length, cross-sectional area (the area you see looking into the pipe to see what's inside), and stuff inside the pipe all affect its resistance to water.Electrical resistors are very similar—affected by the same three factors. If you make a wire thinner or longer, ...
a) Find the power of the light put off by the sun. b) Find how much total power (in watts) the earth gets if the cross-sectional area of th How to convert kW to kVA with a formula A residential customer of an electric utility uses x kW-hr of ...
(it will sink in the process fluid) and it must extend from the lowest level required to at least the highest level to be measured. As the process fluid level rises, the column displaces a volume of fluid equal to the column’s cross-sectional area multiplied by the process fluid level...
