Sorry Iīll write it again itīs difficult to write formulas here


I asume Mass= 50000kg
Thus W= 50000*10= 500000 N.
Being a= CLB Angle
-1: L= W*Cos(a)=
-2: Sin(a)= (T-D)/W

From 0: L=D*12

thus with 1: D*12=W*Cos(a)

D=(W*Cos(a))/12 = W/12Sin(a) **1/Sinx= Cosx

In 2:

Sin(a)=(T-(W*Cos(a))/12)/W

Sin(a)=(T-(W/12Sin(a)))/W

Sin(a)=((12TSin(a)-W)/12Sin(a))/W

Sin(a)=((12TSin(a)-W)/12WSin(a))

1=(12TSin(a)-W)/12W

12W= 12TSin(a)-W

13W= 12TSin(a)

13W/12T=Sin(a)

***a= Sin-1(13W/12T)***

When you find the CLB Angle "a" CLB GRAD= TAN(a)*100

ie 45 CLB angle= 100% CLB GRAD (for every ft you advance horizontaly you climb one ft verticaly)
