Description

Предлагаемыйприбор предназначаетс  дл  решени  тригонометрических задач и задач механики графическим путем.The proposed instrument is intended to solve trigonometric problems and mechanics problems graphically.

На чертеже фиг. 1. обозначает общий вид прибора, фиг. 2 - оборотную сторону сектора.In FIG. 1. denotes a general view of the device; FIG. 2 - the reverse side of the sector.

Обыкновенный штангенциркуль (фиг. 1) снабжен прорезью 10 вдоль его линейки 2 (фиг. 1), по которой на креп щем болтике 7 ходит разделенный на градусы пр моугольный сектор 4, снабженный нониусами 5 и 6 (фиг. 1). С оборотной стороны сектора 4 имеетс  шкала 4а с прорезью, котора  проходит через центр вращени  сектора и нулевое деление его градусной шкалы и по которой ходит направл юща  С (фиг. 1), служаща  в то же врем  осью вращени  нониуса 8а, подвижного на шкале 4а, и нониуса 8Ь, подвижного по шкале 3, котора  своим концом присоединена к каретке / (фиг. 1) с нониусом , передвигаемой по прорезу 10 линейки 2 штангенциркул .An ordinary vernier caliper (Fig. 1) is provided with a slit 10 along its ruler 2 (Fig. 1), along which a rectangular sector 4 divided by degrees 5 and 6 is fitted on the fastening bolt 7 (Fig. 1). On the reverse side of sector 4 there is a scale 4a with a slit that passes through the center of rotation of the sector and the zero division of its degree scale and along which the guide C (Fig. 1), which serves at the same time as the axis of rotation of the nonius 8a, moving on the scale 4a , and the nonius 8b, movable on a scale 3, which at its end is attached to the carriage / (Fig. 1) with a vernius moved along slot 10 of the rule 2 vernier caliper.

При пользовании прибором на практике, например, при переводе на градусы поворота маховика двигател  внутреннего сгорани  поWhen using the device in practice, for example, when translating the degrees of rotation of the flywheel of an internal combustion engine to

The length of the connecting rod is installed on the ruler 3 with the nonius 8 a and is fixed with a screw. Line 2 establishes the sum of the lengths of the connecting rod.

При правильной установке: нониус 1 должен указывать на О, при чем по установке нониуса по данным регулировки в mm хода поршн  данные регулировки в градусах по маховику мотора получаютс  по шкале 4 и нониусу 5.degree scale 4 along ruler 2 when using vernier 6, after which scale 4 is fixed with screw 7. When properly installed: vernier 1 should indicate O, and when adjusting vernier according to adjustment in mm piston stroke, adjustment data in engine flywheel are obtained on a scale of 4 and nonius 5.

При решении тригонометрических задач нужно пользоватьс , шкалами 3 4а, как катетами,When solving trigonometric tasks, it is necessary to use scales of 3 4a, like legs,
