A 4-inch square block with a length of 32 inches made of a material with E= 120 ksi and a = 78 x 10-6/°F is fixed at A as shown in the figure. At initial temperature, a 0.10-inch gap exists between the block and the rigid support at B. B (1) 0.10 in. 32 in.
[Select] 100°F, the internal axial force is [Select] [Select] 100°F, what is the normal stress (in ksi) in the block? (a) If the temperature is increased by kips (kilopounds). V (b) If the temperature is increased by [Select] 100°F, the normal strain of the block [ Select] (c) If the temperature is increased by (d) At the increased temperature, the normal stress of the block if there is no rigid support at Bis ksi. με. (e) At the increased temperature, the deformation of the block if there is no rigid support at B is inches.
