# 1. Forces

## 1.1. How will torsion affect the structure?

## 1.2. How will compression affect the structure?

## 1.3. How will tension affect the structure?

## 1.4. How will shear affect the structure?

## 1.5. What is the maximum amount of weight this structure can carry before it fails?

## 1.6. Where are the strongest and weakest points of application?

## 1.7. Which structural components would be most effective on this structure?

## 1.8. How will the outcome of forces being applied to a symmetrical design be different compared to a structure that is of asymmetrical design?

## 1.9. Would faulty construction be very effective if the structure were to fail?

## 1.10. Could foundation failure even occur when building the crane?

## 1.11. Would a string be convenient as the lifting part of the pulley mechanism?

## 1.12. New node
