I went through this my self year ago. When I purchased a new mirror from Terry O. The new mirror had the same focal ratio rating but the focal length turned out to be a little shorter than the original mirror. I realized this when I found that I did not have enough infocus for any...
How to calculate the theoretical strain? and the Elastic Modulus? Stress-Strain diagram A stress-strain diagram is plotted during the tensile testing of a material to determine the relationship between the stress and the strain at different loads. Various properties of the material are calculated ...

% replicate [X] to be the same size as [Z] for plotting: Xcol{ijk,:} = repmat([Xcolumn,Xbotbeam],1,NumberStory); Zcol{ijk,:} = [Zcolumn,Zbotbeam]; %% Cooridinate Point Ordinary Segment (os) % calculate span length of ordinary segment ...
outline to form your truss. Measure from the center of the top edge of your bottom cord to the inside of the peak. Cut one 2-by-4 to this length. Mark the center of one end using chalk. Cut the corners from that end at 18.43 degrees, so that they meet on the mark to form a ...

Flat or Horizontal Projection of Roof Length = BL + GEO - this is also the true roof length = RLTrue Measure or estimate or calculate the roof rise - the height increase from the eaves to the ridge. Get roof width: Use the roof rise to calculate the true roof width as follows: ...
Calculate the internal shear force and bending moment for the simply supported beam shown below. Using a computer program, plot V(x) and M(x). a) A mass of 50\text{ kg} is suspended from a steel wire of diameter 1.0 \text{ mm} and length 11.2 \text{ m} . The elastic modulus...
I have a dataset containing 16,725 measurements across 1994 days. Each measurement begins when the header (column 1) reads 21, but the length varies each day. For my variable of interest (column 2), I'm looking to calculate the slope under certain conditions. For example, ...
With custom formula columns in the Markups List, I’ve built tools that calculate the linear feet of bars. When you draw a slab or panel area, Revu gives you the length and width; now you just have to add formulas to incorporate the bar spacing and edge distances. Equipment Staging Over...
