22
Q

Motion will occur in a lever when…

A

When the effort that is supplies exceeds the load

23
Q

If the trapezius inserts 6cm from fulcrum and the weight of the skull (8kg) is 8cm from fulcrum, how much effort does the trapezius have to provide to hold head in anatomical position

A
  • Effort x effort arm = load x load arm
  • Effort x 6cm = 8kg x 8cm
  • Effort = 64/6
  • Effort = 10.7kg
24
Q

If the distance of the load from the fulcrum gets bigger what happens

A

If the distance of the load from the fulcrum gets bigger, the effort that is needed to support the load would also increase
