▼ Because the block is not moving, the sum of the x components of the forces acting on the block must be zero. Find an expression for the sum of the x components of the forces acting on the block, using coordinate system b. Express your answer in terms of some or all of the variables F, Fi, F, and 8. ▸ View Available Hint(s) ΣΕ = 0 = Submit Part E VE ΑΣΦ BE ? To find the magnitude of the normal force, you must express F₁ in terms of F since Fr is an unknown. Using the equations you found in the two previous parts, find an expression for F involving F and 9 but not Fr. ▸ View Available Hint(s)
