Question

The figure below shows a rock climber climbing up Devil's Tower in Wyoming (a) Identify all forces acting on the dimber. (Select all that apply.) O their weight D tension in their muscles normal force from the rock friction from the rock (b) Draw a free body diagram for the climber. s1 FN1 FN1 FN1 FN2 FN2 S2 s1 FN2 FN2 s1 FN1 FN1 FN2 FN2 S2 s1 (c) How does the climber support their weight? (Select all that apply.) normal force on their feet D frictional force on their hand D frictional force on their feet normal force on their hands

Explanation / Answer

part a:

the forces acting on the climber:

their weight, in vertically downwards

normal force from the rock in horizontal direction

friction from the rock is in vertically upwards

so first,third and fourth options are correct.

part b:

depending upon the force description from part a, the free body diagram will be s given in option a.

part c:

the weight is supported by the vertically upward forces.

which are frictional forces on their hands and theirs feet.

hence second and third options are correct.
