Challenge Problems
Push your limits with challenges.
Question 1
A fixed pulley system is used to lift a 100 kg load. If the pulley is frictionless, calculate the force needed to lift the load.
💡 Hint: Use the formula for weight (W = mg).
Question 2
A movable pulley is used to lift a load of 200 kg. If the mechanical advantage is 2, what is the force required to lift this load and what distance will the effort travel compared to the load?
💡 Hint: Consider mechanical advantage and how it relates to force and distance.
