The patella P located in the human knee joint is subjected to tendon forces T₁ and T₂ and a force F exerted on the patella by the femoral articular A. If the directions of these forces are estimated from an X-ray as shown, determine the magnitudes of T₁ and F when the tendon force T₂ = 6 lb.. The forces are concurrent at point O.
