Q) The diameters of a frustum of cone of a pivot bearing of a shaft are 30 cm and 60 cm and its semi-cone angle is 60 degrees. If the shaft carries a load of 50 kN and rotates at 300 r.p.m, assuming uniform intensity of pressure, determine the magnitude of pressure and the power lost in friction. Take the coefficient of friction as 0.02.

Transcribed Image Text:Q) The diameters of a frustum of cone of a pivot
bearing of a shaft are 30 cm and 60 cm and its
semi-cone angle is 60 degrees. If the shaft carries
a load of 50 kN and rotates at 300 r.p.m,
assuming uniform intensity of pressure,
determine the magnitude of pressure and the
power lost in friction. Take the coefficient of
friction as 0.02.
