The hot-air balloon shown below is tethered with three mooring Cables. The force Tb in cable DB has a magnitude of 2230 N.
a.) Express Tb in Cartesian vector form.
b.) Determine the magnitude of the rectangular component of the force Tb along DA.
c.) Determine the angle alpha between the cables DA and DB.
Since the picture can't be uploaded, the balloon is at point D=(0,0,8)m and is connected by lines to points A=(10,5,0)m, B=(5,-5,0)m, and C=(-7,-2,0)m.
Tension Tb describes vector DB.
