Explanation:

(a) Spanner has a long handle to produce larger turning moment and 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 perpendicular distance.

(c) In order to increase of moment of force, handle is provided near its arm. Small force is applied at the handle.

(d) Moment of force is product of force and perpendicular distance. It is

easier to open the door applying force at the free end.

(e) A Polter’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.
