Rigging Seminar - Mechanical Advantage

[20:04] RiggingStudent: hi davee
[20:04] RiggingStudent: can i ask you a question please
[20:04] eProf: yup uhhuh
[20:05] RiggingStudent: for the homework...when a line is at an angle, does it have any effect on the tension?
[20:05] eProf: in the mechanical advantage problems?
[20:05] RiggingStudent: yissir
[20:05] eProf: does the line effect the tension? or does the angle effect the tension?
[20:05] RiggingStudent: the angle
[20:06] eProf: in the "real world" angle does effect the tension in the line
[20:06] eProf: but for the sake of this exercise, you can assume that the angle doesn't matter
[20:07] RiggingStudent: gotcha
[20:07] RiggingStudent: perfecto
[20:07] RiggingStudent: thankyou!!
[20:07] eProf: np
[20:07] RiggingStudent: hmm..are we going to study this subject in further detail?
[20:07] RiggingStudent: like with angles....and etc
[20:07] eProf: only in so much as it applies to double purchase fly systems
[20:07] RiggingStudent: or is this as complex we're gonna go in terms of pulleys..
[20:08] RiggingStudent: cool..
[20:08] eProf: we might look very briefly at bridles later in the semester
[20:08] eProf: which would use angled loads
[20:08] eProf: but I am not sure yet
[20:09] RiggingStudent: ohh okok
[20:09] RiggingStudent: I used my old hs physics book which helped.
[20:10] eProf: thats a good impulse
