=Oorma COS (30) +0-0.49 + Fucas (250) +0.98 = Cos 0 5. Solve for F4 and F1. And the masses, m and m4 that place the table into equilibrium. F1 F4 m1 1.43 0.565.146m Click or tap here to enter text. m4 0.058 6. Explain why can't you have a negative mass and what do you do about your answer? 7. Place the amount of mass solved for in the previous step and observe if the ring no longer touches the center pin. Remember the mass hangers have mass. If the ring still touches the center pin check your calculations again. F = mc
