Question 1

The ratio of the load causing collapse to the working load is called the
1. Load factor
2. Safe factor
3. Shape factor
4. Base factor

Question 2

Correct Answer - Option 1 : Load factor

Explanation:

Load factor in plastic design:

Load factor is the ratio of ultimate collapse load to the working load that can be applied on the structure.
Load Factor = Factor of safety x Shape factor.
As factor of safety at member level largely depends upon the nature of loading, support conditions and mode of failure, so the load factor also depends upon those factors.
The shape factor of a member solely depends upon the geometry of the cross sectional area, so the load factor also depends on the geometrical shape of the member.
Normally a load factor of 1.7 to 2 is used in plastic design method.
