物理の剛体力学での質問です。 この問題の7がわかりません。

水平な荒い床の上に、図のような形状で質量 mの箱に力を加えたとき,すべる条 件と倒れる条件を調べてみよう。箱に対して床からの高さがんの位置に右向きで大 きさFの外力を加えた。重力加速度の大きさをgとして、以下の を埋めよ。 a F h まず,すべっても倒れてもいない静止している状態を考えよう。このとき,箱が 床から受ける垂直抗力をの大きさをN, 静止摩擦力の大きさをfとすると,この箱 の力のつりあいの式は, 水平方向が 1 A…0 鉛直方向が 24 となる。 [A] すべるときの外力の大きさを求めよう。すべり出す直前を考えると,静止摩擦 力の大きさが最大になるので,静止摩擦係数 μとNを用いて,f= 3A…3 となる。0, 2,3よりf.Nを消去すると、F= 4 となる。 -F
