Knee Extension. Consider a person wearing a cast on their foot of weight W.-1ON with their knee in the following configuration at an angle of ß=60° with the horizontal. The foot is not touching the ground. Let the insertion of the patellar ligament be at a distance A=0.2 m from the knee joint O, the center of gravity of the leg at a distance B from O, and the foot at a distance of Cfrom O. All distances are measured along the length of the leg. Let the weight of the leg be WL =40 N. Let B=4A and C=8A. Let the force in the patellar tendon Fm have a pull angle of 0=15° with the proximal tibia. (a) Draw an appropriate free body diagram of the problem. [provide your answer in your uploaded work]

A war airship leaves the port in Liberio and flies 175 km at 48.0" East of North and then changes direction to fly 235 km at 54.0 South of East. However because of the damage it took, it made an immediate emergency landing on a desert. When the airport sends out a rescue crew, how far and in what direction should this crew fly to go directly to the airship? Solve for the magnitude of the resultant vector Solve for the angle and specify the direction of the resultant vector.
Determine the magnitude and direction of the resultant force. Express the resultant force using Cartesian vector notation. 500 N 60 300 mm 424 N 400 N 200 mm

A brother and sister are playing in the woods, when suddenly the brother realizes that they are separated. The last place he remembers seeing his sister is at a particularly large tree. The brother traveled d = 21.0 m at 8, 26.0 from the tree then turned and traveled de 11.0 m at 0₂= 140". Meanwhile, the i sister traveled ds = 17.5 m at an angle of 0-117 from the tree. The angles are given with respect to east with counterclockwise being defined as positive(Eigure 1) Figure d₁ 8₂ 1 of 4) > Part C-Distance to home After the boy has found his sister, they want to travel the shortest path home.
