A steel rod, which is free to move, has a length of 200 mm and diameter of20 mm at a temperature of 15°C. If the rod is heated uniformly to 115°C,determine the length and the diameter of this rod to the nearest micron atthe new temperature if the linear coefficient of thermal expansion of steel is12.5 * 10-6 m/m/°C. Is there a stress on the rod at 115°C?

A steel bar is held by two fixed supports as shown in the figure and is subjected to an increased temperature of AT = 200°C. If coefficient of thermal expansion and young's modulus of elasticity of steel are 11 x 10-6/°C and 200 GPa respectively, the magnitude of thermal stress (in MPa) induced in the bar is
The rods of different materials are connected and placed between rigid supports at A and D, as shown in the figure. Properties for each of the three rods are given below. The bars are initially unstressed when the structure is assembled at 25°C. After the temperature has been increased to 90°C, determine:
A steel plate used for polymer forming is to be bent into a circular shape having an inside radius of 10 m. What maximum thickness can be used for the plate if the normal stress is not to exceed 267 MPa? Assume that the modulus of elasticity for the steel is 201 GPa.
A cylindrical specimen of a metal alloy 47.5 mm long and 9.72 mm in diameter is stressed in tension. A true stress of 397 MPa causes the specimen to plastically elongate to a length of 54.3 mm. If it is known that the strain-hardening exponent for this alloy is 0.2, calculate the true stress (in MPa) necessary to plastically elongate a specimen of this same material from a length of 47.5 mm to a length of 55.8 mm. i MPa
