Challenge Problems
Push your limits with advanced challenges
A crane is lifting a load of 3000 kg with a boom weighing 600 kg. If the crane's counterweights total 4000 kg, calculate the tipping and resisting moments, given the fulcrum distance is 5 meters.
💡 Hint: Use the formula for moment, which is force multiplied by distance.
Design a scenario where a mobile crane is inefficient for lifting heavy materials. Describe the factors leading to the inefficiency, citing mobility and load capacity.
💡 Hint: Consider the environment and weight of the materials.
