Question
A tree contractor has been hired by a homeowner to
remove a damaged tree from a previous storm. The top of
the tree broke off, leaving the trunk in the ground. The
arborist will remove the tree by attaching a rope near the
top and cutting the base close to the ground. The scenario
is shown in the figure.
The distances in the figure are z = 12.0 m, h
y = 4.83 m and x = 11.96 m. If the arborist pulls on the
rope with a force of magnitude F = 35.1 N, write the
expression for the torque 7 with respect to the base P of the
tree using ijk unit vector notation,
7 = txi + Tyj + T₂k
where Tx, Ty, and Tz are the values of the torque
components in the x-, y-, and z-directions, respectively.
