Choose the wrong statement |
| A. | the frictional torque transmitted by a shaft fitted with a large number of collars is the same as transmitted by a shaft with one collar |
| B. | the frictional force for uniform pressure, in case of a flat pivot bearing, can be assumed to be acting at a distance of two-thirds of the radius of the shaft from the axis of shaft. |
| C. | when horse power lost in friction is to be determined, uniform pressure is assumed for safe design of bearing |
| D. | the frictional force for uniform pressure, in case of a flat collar pivot bearing, can be assumed to be acting at a distance of half of the sum of internal and external radii of the shaft |
| Answer» D. the frictional force for uniform pressure, in case of a flat collar pivot bearing, can be assumed to be acting at a distance of half of the sum of internal and external radii of the shaft | |
