The drawing shows an A-shaped ladder. Both sides of the ladder are equal in length. This ladder is standing on a frictionless horizontal surface, and only the crossbar (which has a negligible mass) of the " A " keeps the ladder from collapsing. The ladder is uniform and has a mass of 15.2Kg. Det k mine the tension in the crossbar of the ladder.

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=14.7 m,, h=1.45 m,, y=5.66 m and x=8.00 m. If the arborist pulls on the rope with a force of magnitude F=36.8 N,F=36.8 N, write the expression for the torque ττ with respect to the base P of the tree using ijkijk unit vector notation, →τ=τxi+τyj+τzk where τx,τy,and τz are the values of the torque components in the x-,, y-, and z-directions, respectively.
