Question

# 11 is the answer b or d ? please clarify

11) If a vertical ground reaction force (GRF) acts through the centre of pressure of the foot, which is in front of (ie, to the right of) the ankle, which statement is net true with respect to the resulting ankle torque? a) The ankle plantarfiexors will have to generate an internal negative moment to negate the effect of the GRF b) The GRF will produce a counterclockwise external moment c) The internal and external moments must be equal for the ankle to remain in its current position 따 The ankle plantarflexors will have to generate an internat positive moment to negate the effect of the GRF

Answer 1

11 )

Taking into account that the anti clockwise minutes are sure and the clockwise minutes are certain.

Since the focal point of weight point is in the front piece of the lower leg,

the power will create a anti-clockwise outer minute as

for the lower leg, and for the lower leg to remain static,

it ought to produce an equivalent and inverse minute.

The lower leg plantar flexors append to the back piece of the lower leg.

So to neutralize the minute created by the GRF,

the muscles ought to produce a clockwise minute about the lower leg.

Henceforth the plantar flexors ought to produce an interior negative minute to counter GRF.

so the wrong is Option " D "
