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.

(e) A potter turns his wheel by applying a force through the stick near the rim of wheel.
(a) Spanner has a long handle to produce larger turning moment and a small force is applied at the end of handles.
(b) The hand of large diameter has a large perpendicular distance. The moment of force depends upon the perpendicular distance.
(c) In order to increase the moment of force, the handle is provided near its arm. A small force is applied at the handle.
(d) Moment of force is the product of force and perpendicular distance. It is easier to open the door applying force at the free end.
(e) A potter’s wheel has a wheel pivoted at the centre. The potter turns the wheel by means of a stick at the rim of the wheel. He increases the perpendicular distance.
