a) Bentuk fisik mistar biltmore<\/strong>
\nBentuk fisik mistar biltmore berupa mistar yang diberi tongkat penyangga setinggi dada (1,30 m) dan mempunyai skala (satuan ukur). Skala mistar biltmore pada awalnya berupa selang diameter, kini telah diubah ke dalam satuan ukur. Satuan ukur yang digunakan adalah cm dengan satuan ukur terkecil dalam mm.<\/p>\n

b) Dasar Kerja
\n<\/strong>Perhatikan Gambar 40 di bawah ini.
\n\"image\"<\/a>
\nGambar 40 Cara penggunaan mistar biltmore<\/p>\n

Cara penggunaan garpu pohon adalah :
\n(1) Impitkan mistar pada batang.
\n(2) Geser ke kiri-kanan hingga MBQ merupakan garis lurus.
\n(3) Skala yang terbaca pada S merupakan diameter batang.<\/p>\n

c) Kesalahan ukur keliling batang pohon
\n<\/strong>Kesalahan ukur keliling batang pohon pada saat menggunakan garpu pohon adalah (Gambar 41) :
\n
\"image\"<\/a>
\nGambar 41. Kesalahan ukur dengan mistar biltmore<\/p>\n

Kesalahan yang terjadi bila kedudukan mistar miring (tidak sejajar dengan bidang datar). Akibatnya menyebabkan kesalahan sebesar :
\nEd = B1<\/sub>S1<\/sub> \u2013 BS
\ndengan,
\nBS = kedudukan alat benar
\nB1<\/sub>S1<\/sub> = kedudukan alat salah
\na = sudut kemiringan alat<\/p>\n

Kesalahan sudut diperoleh dari :
\n
\"image\"<\/a>
\nsehingga,
\nBS = TB + TS
\nBS = (TB1 x cos \u03b1) + (TS1 x cos \u03b1)
\nBS = (TB1 + TS1) x cos \u03b1<\/p>\n

maka,
\nEd = B1S1 \u2013 BS
\nEd = B1S1 \u2013 (TB1 + TS1) x cos \u03b1
\nEd = B1S1 \u2013 B1S1 x cos \u03b1
\nEd = B1S1 x (1 – cos \u03b1)<\/p>\n","protected":false},"excerpt":{"rendered":"
