Find the greatest and smallest values of the velocity ratio of two shafts joined with a universal coupling when the axis are 30o. Produce a graph of velocity ratio against angle for f to proof the calculated results.

In a spur gear arrangement, the driver has 80 teeth of 39 mm pitch. Find the power, if it can transmit a tangential force of 60 N. Take speed of driver as 150 rev/min. Insert your answer for power in watt correct up to at least a third decimal place.

Find the greatest and smallest values of the velocity ratio of two shafts joined with a universal coupling when the axes are at 60o to each other. Produce a graph of velocity ratio against angle for f to proof the calculated results.

In a spur gear arrangement, the driver has 70 teeth of 26 mm pitch. Find the power, if it can transmit a tangential force of 100 N. Take speed of driver as 160 rev/min. Insert your answer for power in watt correct up to at least a third decimal place.

5. For the engine-transmission-propeller problem shown below, The engine generates a torque of 219lb-ft, and it is bolted to a frame at locations A and B. The transmission reverses the rotation direction. The transmission ratio is 1.5 (i.e. the propeller speed is -1/1.5 the engine speed, the minus sign indicates the change in direction). d. Sketch the free body diagram. Be sure to show the torques at the input and outputs to the different components. Note the change in the rotation direction between the engine and shaft. e. Solve for the reaction forces at the bolt supports of the engine, if the distance between them is 1 ft. Propeller Engine Reduction ratio 1.5 Engine is attached B
