Neco Model Questions Vol1 2023 Agricultural Science Question 42 diagram

The diagram shows a tractor power‑take‑off system. The engine drives a pulley of diameter 0.5 m (driver) which is connected by a belt to a driven pulley of diameter 0.2 m. The driven pulley is mounted on the same shaft that turns the tractor wheel of radius 0.6 m. The engine runs at 1500 rpm. (a) Determine the rotational speed of the driven pulley in revolutions per minute. (b) Calculate the linear speed of the belt in metres per second.

Answer Options

Correct Answer A. Driven pulley speed = 3750 rpm; belt speed ≈ 39.3 m/s.
B. Driven pulley speed = 4500 rpm; belt speed ≈ 47.1 m\/s.
C. Driven pulley speed = 3500 rpm; belt speed ≈ 36.5 m\/s.
D. Driven pulley speed = 3000 rpm; belt speed ≈ 31.4 m\/s.
Correct Answer
A
Correct Option:
Driven pulley speed = 3750 rpm; belt speed ≈ 39.3 m/s.
