Neco Model Questions Vol1 2018 Physics Question 6
Practice essay / theory question 6 from the 2018 Neco Model Questions Vol1 Physics examination. This question covers machines, simple machines, lever, torque, mechanical advantage, efficiency, friction .
The diagram shows a simple compound machine consisting of a uniform rigid beam AB of total length 2.0 m pivoted at point O. The fulcrum O is located 0.6 m from the left end A and therefore 1.4 m from the right end B. A load of weight W = 500 N hangs vertically from end A. The right end B is attached to a mass‑less rope that passes over a fixed frictionless pulley C fixed to the ceiling; the other end of the rope is pulled vertically upward by an effort force F applied at B. The pivot at O experiences a resisting (frictional) torque of 10 N·m opposing the rotation caused by the effort. The system is in static equilibrium.
