2. There is a V-Belt drive that facilitates us to connect a motor to a compressor. Consider the data that we have with us: Motor - Pulley Compressor - Pulley Pitch diameter (mm) Speed (rpm) 300 900 1440 480 Coefficient of friction 0.2 0.2 | The pulleys are a meter apart from each other (this is the center to center distance). The belt can handle a maximum of 850N of tension. The density of composite material of belt is 0.97g/cc. Refer to the below figure for cross-section of belt: 22- b2 40 14 Based on the above data, if the number of belts required for this application are 'k', then the value of k is?
