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?
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)
A 10,000 LB LOAD IS SUPPORTED BY A ONE INCH-DIAMETER STEEL ROD (E = 29,000 KSI) AS SHOWN ABOVE.
A. WHAT IS THE STRESS IN THE ROD?
B. WHAT IS THE STRAIN IN THE ROD?
C. HOW MUCH DOES THE ROD ELONGATE?
A- Find this Maximum Shear stress () in the Wood Beam above.
B- Circle which of the following is true(circle1)
C- If the maximum allowable shear stress is only 120 psd, does the saction have adequate strength?
