f the centrifugal action in that partof the belt in contact with the pulley. This centrifugal actionalso diminishes the normal pressure of the belt on the pulleyrim, and therefore decreases the frictional resistance. For TRANSMISSION BY FLAT BELTS AND ROPES 229 speeds beyond 3500 feet per minute… … <7Fcos(9O-f+0) ^Tsin(90-f) T cos (90-—) Fig. 5. Consider the very small arc of the pulley subtending the angledS, and let dF denote the centrifugal force set up in the partof the belt in contact with this arc. We have the static equation 2 T cos (90° - -) = r^^ sin (90° - - + A2rsin-= CdFcos(-…
