La catenària

LA CATENARIA
Si pengem un cable dels seus extrems entre pals, aquest formarà una corba que respon a una fórmula. Originalment el problema s'hauria plantejat amb un cadena en comptes d'un cable.

es tracta d'una funció cosinus hiperbòlic

l'obtenció de la fórmula està desenvolupada en l'enllaç 

hi ha alguns RECALL al llarg del vídeo i arranjaments enginyosos que convé destacar.

1. la fórmula per al càlcul de la longitud de la funció. es pot tenir més detall aquí
2. la modelització de la catenària i els seu diagrama del cos lliure

Mstsc

Creates connections to terminal servers or other remote computers, edits an existing Remote Desktop Connection (.rdp) configuration file, and migrates legacy connection files that were created with Client Connection Manager to new .rdp connection files.

Syntax

mstsc.exe {ConnectionFile | /v:ServerName[:Port]} [/console] [/f] [/w:Width /h:Height]

mstsc.exe /edit"ConnectionFile"

mstsc.exe /migrate

Parameters

ConnectionFile

Specifies the name of an .rdp file for the connection.

/v:ServerName[:Port]

Specifies the remote computer and, optionally, the port number to which you want to connect.

/console

Connects to the console session of the specified Windows Server 2003 family operating system.
