What happened to ADAMS/Engine
Last year MSC announced they are selling the ADAMS/Engine module to FEV so that they become world leader in Multibody Dynamics.. etc Press release from FEV Since then, I am unable to see anything in FEV's website where they sell, support or develop the ADAMS/Engine software. It is sad that we...- jalexiou

Sag Tension Equations when Temperature Changes
This paper will be given to you by the technical support staff of SAG10 software (www.sag10.com). Or ask directly from SAG10 tech support at: http://www.acasolutions.com/contacts/tech_support/software_support.asp It may be in a IEEE library also. PS. All of the white papers on sag and...- jalexiou

Increased tension due to pole raising
Roughly the span has become from 600 ft to 600.0833 ft. Consider this a change [Δ]S=0.0833. To calculate the change in horizontal tension, if the total cable length is unchanged use [Δ]H/[Δ]S [≈] 12[·]H[³]/(S[³]w[²]) where H is the horizontal...- jalexiou

cable loads
Actually if you consider the shape of a beam under its own weight w, the shape is still a catenary {Hint: Catenary constant is a=(E I/w)^(1/3)}. Now add axial tension T to it, and it is still a catenary. The catenary constant is now whatever "a" satisfies the equation...- jalexiou

FORMULA TO CALCULATE DIAMETER OF BUNCHED ELECTRICAL CORES
If all the strands are the same diameter it is very simple. D = d*(2*LAYERS-1) with d the strand diameter & LAYERS the number of strand layers. Typically the number of strands N equals N = 1+3*LAYERS^2-3*LAYERS. For example a N=37 strand cable with d=.1466" has LAYERS = 4 because...- jalexiou

conductor creep
Typically conductors experience only primary creep and thus obey the power law of, strain = C*time^m for a constant stress & temperature level. Here C, m are creep coefficients. In general, C depends on both temperature and the stress level with a similar equation C=K*T^n*(stress/uts)^k, where...- jalexiou

cable loads
Alcoa's SAGTEN is currently named SAG10(tm) and below is a link to an online paper with all the catenary equations of unlevel/level spans. These are just half the story in transmission lines. The most important part is the cable behavior (stress-strain curves and creep rate). A lot of people...- jalexiou
