Question:
The rigid bar ABCD is supported by a pin at B and restrained by identical steel bars at C and D, each of area 750 mm 2 . Use E=200 GPa and a= 11.7x10 -6 /oc.
a) If P=13977.82286 N and the stell at D is stress-fress, determine the change in temperature indicate whether it is increasing or decrease in temperature.
b) If P=34121.5875 N and the stell at C is stress-fress, determine the change in temperature indicate whether it is increasing or decrease in temperature.
c) If the stress of stell at D is twice as the stress of steel at C, and the change in temperature is 55oC, determine P.
