Calculate the contact angle (in deg) for the smaller of two pulleys with diameters of 500mm and 200mm. the tension ratio is 3: 1 and distance between parallel shafts is 700mm

Explanation:

Given that

Distance between pulleys= 700 mm

We have to find contact angle

In general application pulleys are connects in open configuration,So the contact angle given as follows

For small pulley

primary groups shape your individual development
