Neco 2022 Agricultural Science Question 3 diagram

A simple lever is used in a farm seed‑planter to lift a seed hopper. The lever is a rigid wooden beam 120 cm long. A fulcrum is placed 40 cm from the left end of the beam. A load of 200 N is attached to the right end of the beam. The farmer applies the effort at the left end of the beam.

Question Parts

( a )

Determine the mechanical advantage (MA) of the lever.

( b )

If the farmer wants to lift the 200 N load, what is the minimum effort force that must be applied at the left end? (Assume an ideal lever with no friction.)

( c )

Discuss two advantages of using this lever‑based seed planter over manual hand sowing, focusing on labour efficiency and seed‑spacing uniformity.
