Embodiment Construction

[0012] like figure 1 As shown, the angular velocity vector synthesis demonstrator includes: a chassis 1, two fixed brackets 5 installed on the chassis, the upper end of the fixed bracket is connected to a half-arc scale 6 by screws, and three movable arrows are distributed on the semi-arc scale 6; The chassis is fixed with a right-hand wheel 2, a left-hand wheel 3 and a roller skating 7 in a triangle, such as figure 2 As shown; the left and right handwheels are respectively composed of a round rod fixed on the chassis and a freely rotatable disc set on the round rod. The disc is fixed in the axial direction of the round rod; A sphere 4 is placed on the sphere, red spots are evenly distributed on the surface of the sphere 4, and the interior is filled with gas.

[0013] Wherein the size of the chassis 1 is preferably ?180×10mm.

[0014] Turn the left hand wheel 3 to make the sphere 4 rotate at a constant speed along a certain axis of rotation. The red dots on the ball draw a...

Abstract

The invention discloses an angular velocity vector synthesis demonstration instrument. Demonstration angular velocity physical quantity is a vector, and a synthesis angular velocity vector and a dimidiate angular velocity vector abide by a parallelogram law for vector synthesis. The angular velocity vector synthesis demonstration instrument comprises an underframe and two fixing supports mounted on the underframe, the upper ends of the fixing supports are connected with a semi-circular-arc scale through screws, three movable arrows are distributed on the semi-circular-arc scale, a right handwheel, a left handwheel and a wheel slider are triangularly fixed on the underframe and form a plane, a ball is placed on the plane, and red points are uniformly distributed on the surface of the ball.

Description

technical field [0001] The invention relates to the technical field of teaching tools, in particular to an angular velocity vector synthesis demonstrator. Background technique [0002] Angular velocity vector is a difficult point in physics. A rigid body participates in two different directions of rotation, and the angular velocity vector of one direction rotation is ω 1 , the angular velocity vector rotating in the other direction is ω 2 , then the angular velocity vector ω of the composite rotation of the rigid body is equal to the two angular velocity vectors ω 1 and ω 2 The vector sum of , which obeys the parallelogram law. There is a lack of a compact and intuitive demonstrator in the existing instruments, which brings difficulties to the teaching experiment. Contents of the invention [0003] The object of the present invention is, through the angular velocity vector synthesis demonstrator, demonstrates that the angular velocity physical quantity is a vector, and...
