A 5-inch square block made of a material with E= 150 ksi and a = 78 x 10 6/°F and length of 32 inches is fixed at A as shown in the figure. At an initial temperature of 65°F, a 0.10-inch gap exists between the block and the rigid support at B. B 0.10 in. 32 in.
[Select] the internal axial force is [Select] [Select] what is the normal stress (in ksi) in the block? (a) If the temperature is increased by 105°F, kips (kilopounds). [Select] (b) If the temperature is increased by 105°F, deformation of the block if there is no rigid support at Bis [Select] (c) At the increased temperature, the inches. (d) At what temperature (in °F) would the block just touch the rigid block at B? (e) At the temperature from the previous question, the normal stress is__________ksi.
