Hooke coupling experiment

Tabulate results in the table given. The objective and purpose of this experiment is to investigate the variation in displacement for a single joint at various angles and to show that when two joints are used together with the same intermediate angle, the variation in displacement is cancelled out.

types of universal joint

Therefore, the apparatus having two couplings with a small intermediate shaft, the fluctuations of the output shaft could be reduced especially in machinery provided that the intermediate angles is the same.

Start the scale on the input shaft at zero. Comment on the output shaft velocity versus input shaft angle plot that you have obtained.

Note the reading on the input and output scales. Each piece of apparatus is self-contained and compact.

Therefore, the apparatus having two couplings with a small intermediate shaft, the fluctuations of the output shaft could be reduced especially in machinery provided that the intermediate angles is the same. Input and output shaft rotations. Two independent Hooke's joints with common shaft. What is the significance of the tan input shaft angle versus tan output shaft angle plot? Bench mounted. Hooke's Coupling Apparatus Features Low cost, effective teaching. Repeat for that is one complete rotation for the shaft input. Plot the output shaft angle versus the input shaft angle for both readings, parallel and same side readings in the same graph. Tabulate results in the table given. Tabulate results in the data sheet 6.

Hooke's Coupling Apparatus Features Low cost, effective teaching. Theoretically, the angle between the shafts is proportional to the speed and torque, where the increase of the angle will offer a periodic speed and hence torque fluctuation. From the graph of the output shaft velocity against the input shaft angle, the plot shows that the larger the angle, the speed become periodic with bigger amplitude.

Direct measurement of relative shaft displacements.

universal joint efficiency

Comment on the output shaft angle versus input shaft angle plot that you have obtained2. How well do the velocity variations you found compare with those predicted in theory. By observing carefully, there is a fluctuations for different value of alpha, a, where the larger the value of alpha, a, the bigger the deflection is.

Repeat for that is one complete rotation for the shaft input.
