This type of dynamometer can be classified as follows: 1. Epicyclic train dynamometer 2. Belt transmission dynamometer 3. Torsion dynamometer. EpicydiC train.

A counter weight is placed at the other end of the lever which balances the brake when unloaded. To use this website, you must agree to our Privacy Policyincluding cookie trakn. The annular gear is also keyed to the driving shaft and rotates in clockwise direction.

Due to this, the light does not reach to the eye piece as shown in Figure c. A weight w is placed at the smaller end of the lever in order to keep it in position. Nirmal Kushwaha”— Presentation transcript: The upper block has a long lever attached to it and carries a weight W at its outer end. Absorption dynamometers, and 2. It consists of one, two or more ropes wound around the flywheel or rim of a pulley fixed rigidly to the shaft of an engine.

We think you have liked this presentation. If the eye piece is now moved round by an amount equal to the lag of disc B, then the slot in the eye piece will be opposite to the slot in disc B as shown in Figure d and hence the eye piece receives flash of light. The amount of twist depends upon many factors such as torque acting dynamomeger the shaft T length of the shaft l diameter of the shaft D modulus of rigidity C of the material of the shaft.

V-belt drive V-belt is mostly used in factories and workshops where a great amount of power is to be transmitted from one dynamoometer to another when the two. A bright electric lamp L, behind the disc A, is fixed on the bearing of the shaft. Since the tension in the tight side of the belt T1 is greater than the tension in the slack side of the belt T2 ,so the total force acting on the pulley C i. Two stops S, S are provided to limit epicyclc motion of the lever. Engineering College Palanpur Name: The pinion or the intermediate gear meshes with both the spur and annular gears.

Epicyclic-train Dynamometer-torque and power transmitted ()

It is thus obvious that the frame causes movement about E in the anticlockwise direction. The upper end of the ropes is attached to a spring balance while the lower end of the ropes is kept in position by applying a dead weight as shown in Figure.

There is another pulley B called driven pulley mounted on another shaft to which the power peicyclic pulley A is transmitted. It consists of two discs A and B fixed on a shaft at a convenient distance apart Each disc has a small radial slot and these two slots are in the same line when no power is transmitted and there is no torque on the shaft.

A belt dynamometer is introduced to measure directly the difference between the tensions of the belt, while it is running. For a solid shaft of diameter D, the polar moment of inertia for a hollow shaft of external diameter D and internal diameter d, the polar moment of inertia, From the above torsion equation the power transmitted.

The pulleys A and B are connected by means of a continuous belt passing round the two loose teain C and D which are mounted on a T-shaped frame.

The most general motion is a combination of translation. The frame is pivoted at E and its movement is controlled by two stops S,S.

A little consideration will show that when the power is being transmitted, then the driving end of the shaft twists through a small angle relative to the driven end of the shaft.

Rotational Dynamics In pure translational motion, all points on an object travel on parallel paths.
