QUESTIONS AND ANSWERS A GRADED
What is a complex mechanical advantage system? - Answer-Additional pulley or system
added within original system not on haul side system
Count tension of complex MA system is? - Answer-Addition, ex. 2:1 system added
within 3:1 system gives net MA 5:1 (2:1 + 3:1 = 5:1)
Why because joining of pulley or system create complex system has summative effect
on calculation of MA system
What is theoretical mechanical advantage? - Answer-System designed specific needs
identifying features of system that must be built
What is actual mechanical advantage? - Answer-Amount of MA rescuers achieve in
field
What factors decrease theoretical rate? - Answer-Incorrectly sized equipment, rope
twists, drags, cause of friction
What does block and tackle consist of? - Answer-Two double sheave pulley in 4:1
In theoretical MA system identify attachment points for haul roped used in simple MA
system? - Answer-Rope attached to load is odd MA ratio
Rope attached to anchor point is even MA ratio
The belay system is used in? - Answer-Descending and lowering operations as a
redundant safety mechanism to support entire weight load if element fails
Why must component of belay system from rope to anchor point be extremely strong? -
Answer-Component will only be loaded in event of failure in another part of system. The
load is never static always dynamic
What is the anchor of belay system? - Answer-Positioned absorb shock load in worse
case system failures
What is the belay device? - Answer-Controlled belay rescue in motion providing
immediate arrest for uncontrolled motion
What are examples of belay devices? - Answer-Double prusik belays, multi purpose
device
