作用反作用について教えてください ⑴Aから受ける垂直抗力とありますがN1を使って図で表すと2枚目の写真のようになって作用点がBにあると思うんですがなぜAから受けると言うのですか?? ⑵3枚目の丸をつけた矢印は何を表してるのですか? 垂直抗力だったら上向きだと思うし重力だっ... Read More

基本例題 12 力のつりあいと作用・反作用 図のように、水平面上に重さ 18Nの物体A を置き, そ の上に重さ12Nの物体Bを重ねた。 また, 力の記号を以 下のように定める。 B 12 N AI 18 N ・AがBから押される力の大きさ・・・N1〔N〕 ・Aが水平面から受ける垂直抗力の大きさ・・・N2 〔N〕 (1) BがAから受ける垂直抗力の大きさを、問題文の記号を用いて答えよ。 (2) A, B が受ける力の矢印を、問題文の記号を用いてそれぞれ図示せよ。 (3) A, B それぞれについて,力のつりあいの式を書け。 (4) N1, N2 はそれぞれいくらか。 解答 (1) 作用・反作用の法則から、力の大きさの関係は, (BがAから受ける垂直抗力の大きさ) = (AがBから押される力の大きさ)=N[] [] (2) 右の図 (3) 鉛直上向きを正の向きとすると B:N1+(-12)=0 ▲N2 NT A:N2+(-N)+(-18)=0 B B A A A... N2-N-180 NM 12 N B... N-120 18N 注次のようにAの式を書くのは誤り。 ① Nz+(-12)+(-18)=0 (4) B の式から,N=12N ② Nz+(-Ni)+(-12)+(-18)=0 (-12)は「Bが受ける重力」 だから, A の式に 入れてはダメ。 「BがAにのっている影響」 ②ではすでに(-N)で表されている。 これをAの式に代入して, N2-12-180 よって, N2=30N N・・・ 12N, N2...30 N
