e Physics 115 Chapter Of8 erCP11 8.3.P.024. hen a person stands on tiptoe (a strenuous position), the position of the foot is as shown in Figure a. The total gravitational force on the body, F is supported by the force n' exerted by the floor on the toes of one foot. A mechanical model of the situation is shown in Figure b, where T is the force exerted by the Achilles tendon on the foot and R is the force exerted by the tibia on the foot. Find the values of T, R, and θ when Fg-n-580 N. (For θ, enter the smaller of the two possible values between 0° and 90°.) Achilles tendon Tibia 15.00 18.0 cm 25.0 cm Need Help? Read It
