E = 29,000 ksi (kips/in²)
G = 11,200 ksi
Coefficient of thermal expansion = 6.5 x 10-6/ degree F
Given: Steel rods and rigid bar as shown
Strain in rods is zero prior to applying load
After applying load P, strain in rod 2 is 600 x10-6 mm/mm
Normal strain in rod 1
Normal strain in rod 1 if there is a 1mm gap at the connection at B before applying load
Normal strain in rod 1 if there is a 1mm gap at the connection at C before applying load
Given: 11xx1"x4 steel rod
Temperature of rod increases by 250 degrees F
Elongation of the rod
What axial force (in kips) is required to result in an equal elongation?
If the rod is 2' long rather than 4', what is the required force (in kips)
Given: Beam with loading and supports shown
Maximum allowable stress in the steel bar is 30 ksi
Maximum load P that can be supported
Elongation of the bar
Normal strain in the bar
Shear stress in the 3/4"
