Neco 2020 Agricultural Science Question 21
Practice objective / multiple choice question 21 from the 2020 Neco Agricultural Science examination.
Refer to the diagram of a farm machinery setup where a tractor pulls a rope over a fixed pulley to lift a load. The load mass is \(500\\ \text{kg}\), the pulley radius is \(0.20\\ \text{m}\) and has a torque resistance of \(5\\ \text{Nm}\). The coefficient of friction between the rope and the pulley bearing is \(0.15\). Assuming the tractor pulls the rope at constant speed, calculate the minimum pulling force (in newtons) the tractor must exert to lift the load.
