Question 1.
What is u in crane operation?
Show hintHide hint
Think of the base point of balance.
Question 2.
What does the operating radius represent?
Show hintHide hint
Consider the length of the crane's arm.
3Question 3.
What does 'u' represent in crane mechanics?
- Distance from center to load line
- Distance from center of boom to tipping axis
- Distance from load line to ground
Show hintHide hint
Think about who dictates how far the crane can safely reach.
4Question 4.

- True
- False
Show hintHide hint
Remember our discussions about load stability.
Question 5.
A crane is rated for a maximum lift of 100 tons and has an operating radius of 30 feet. If the fulcrum distance is 10 feet, calculate X and discuss its implications.
Show hintHide hint
Remember the value of maintaining balance in all crane operations.
Question 6.
In a scenario where a crane has to lift a load of 200 tons, discuss how changing from standard supports to outriggers would affect its capacity and safety equilibrium.
Show hintHide hint
Consider the enhanced support and balance they provide.
