A man accidentally fell into an open hole in the ground. To lift him out of the hole, three (essentially) weightless ropes connected to three lifting mechanisms are sent down. The man then ties all ropes around his right hand. The tensions in the first and second ropes are respectively 25.0 N, 45.0° clockwise from the vertical and 25.0 N, 45.0° counterclockwise from the vertical. The tension magnitude in the third rope is unknown but its direction is vertically up. If all the vertical components of the tensions are just sufficient to lift the man weighing 490 N out of the hole in an upward direction, what is the magnitude of the tension in the third rope?

A barge is pulled by two tugboats. The barge is aligned horizontally while the rope of tugboat 1 is inclined with the horizontal 0-degrees upward, and rope of tugboat 2 is inclined with the horizontal 'a'-degrees downward. If the resultant of the forces exerted by the tugboats is a 6,261-lb force directed along the axis of the barge and 0=36 degrees, determine the magnitude of the tension (Ib) in rope 1 if a = 51° Answer in 2-decimal places only if applicable, and don't include units.

Two squirrels are sitting on the rope as shown. The squirrel at A has a weight of 1.3 lb. The squirrel at B found less food this season and has a weight of 0.8 lb. The angles and are equal to 49° and 58.8° respectively. Determine the tension force in each of the rope segments (T₁ in segment AC, T₂ in segment AB, and T3 in segment BD) as well as the angle a in degrees. A Note the figure may not be to scale.
