When 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, is supported by the force 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 when i -n-755 N. (For 0, enter the smaller of the two possible values between 0 and 90%.)

When 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 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 when F-n- 755 N. (For 6, enter the smaller of the two possible values between 0 and 90°.)
