**Problem#1 **

A W12x87 Steel Column, 14’tall is subjected to a load of 215 kips The cross sectional area of the column is A = 25.6 in^2

A- What is the compressive stress in the column?

B- Whet is the bearing stress between the steel base plate and the concrete footing?

C- Whet is the bearing stress between the concrete footing and the soil?

**Problem #2**

A- FIND THE FORCE IN MEMBER AC AND THE FORCE IN MEMBER BC (hint, the system above is statically determinant) B- FIND THE STRESSES IN MEMBER AC AND MEMBER BC.

C-WHAT IS THE STRAIN IN MEMBER AC? D- WHAT IS THE CHANGE IN LENGTH (IN INCHES) OF MEMBER AC AFTER ALDING THE LOAD (AND DOES IT STRETCH OUT CR COMPRESS?) – (ELONGATES, SHORTENS CIRCLE 1)
