It is easier to turn the steering wheel of a large diameter than that of a small diameter. Give reason.
Explain the following :
(a) The spanner (or wrench) has a long handle.
(b) The steering wheel of a vehicle is of large diameter.
(c) The hand flour grinder is provided with a handle near the rim.
(d) It is easier to open the door by pushing it at its free end.
(e) A potter turns his wheel by applying a force through the stick near the rim of wheel.
A steering wheel of diameter 0.5 m is rotated anticlockwise by applying two forces each of magnitude 5 N. Calculate the moment of couple applied.
