Question

Advantages and disadvantages of Sliding friction

Answer 1

ADVANTAGES

They have good shock load capacity.

They operate more silently.

They occupy less radial space and are more compact.

They are ideally suited for medium and high speed operation.

DISADVANTAGES

The frictional power loss is more.

They required good attention to lubrication.

They are normally designed to carry radial load or axial load. But it cannot carry both at the same time.

Answer 2

$\huge {\rm{\green{Answer:-}}}$

Advantages of fluid friction:-

Flotation of ship,Hover crafts, hot air balloons etc which helps in transportation

Disadvantages of fluid friction:-

Fluid friction reduces the speed of objects moving through the fluids by opposing their motion.
