If a crane has a tipping load of 2000 kg, and you plan to use it on an uneven surface without outriggers, what adjustments to the lifting capacity should you consider?
💡 Hint: Think about how stability is affected when operating conditions change.
Given the following parameters (P = 1.5m, f = 0.5m, u = 4m, W = 1600 kg, X = 12m), calculate L using the formula provided and state the implications for a crane's setup.
💡 Hint: Double-check each distance against the formula.
