It isn't. An experienced shearer can shear a sheep in about 1 minute with electric shears. The same job by hand would take about 15 minutes. Shearers are paid by the number of sheep that they shear, so hand shearing isn't financially viable.
Yes with electric shears although there has been developed a robotic shearing unit
In the context of material deformation, shearing involves the sliding of material layers past each other, causing a change in shape without changing the volume. Friction, on the other hand, is the resistance to motion between two surfaces in contact, which can affect the amount of force needed for shearing to occur.
People invented washing machines so women would have more time to do other things than washing clothes but hand

Circular is one type. There are manual and hand crank knitting machines.

Hand wash it.

Electric-powered portable cutting knives, motor-driven cloth spreading machines, and gas-powered pressing machines displaced such devices as smaller hand-held irons.
