(2) A composite member is made of a hollow brass cylinder (E 105 GPa, v= 0.32, and a = interference fit over ASTM-A242 solid steel rod (E = 200 GPa, v= 0.3, and a = 11.7x10/°C). The outer radius of brass is 100 mm, the inner radius is 50 mm, and the outer radius of steel is 50.05 mm. The length of both is the same (This implies NO STRESS CONCENTRATION FACTOR involved). Compute (a) the total radial interference of the brass and (b) the temperature difference AT required to easily slip the brass cylinder over the steel rod. For easy insertion, allow a clearance of ½&, see slide 16 of Lecture 9 notes. (Hint: First calculate total interference (8 + ½8), then use definition of a (defined in Lecture 6, slide 26). (c) Compute the interface pressure p of the interference fit at room temperature (use the actual radial interference for this; that is, without clearance). 20.0x10*/°C) Fig. 2

As indicated in Figure 4, a tensile stress is to be applied along the long axis (z-axis) of an aluminium rectangular bar. The width of each edge of the bar is w0 = 2.3 mm, and the length is l0 = 12 mm. The bar's modulus of elasticity and Poisson's ratio are respectively 69 GPa and 0.35. It is believed that the material is isotropic. a)If the elongation of the bar, △l needs to be increased, suggest one suitableparameter that should be change on the system. Consider the material of thespecimen is maintained with aluminium. Justify your answer in calculation.

PLEASE ANSWER ASAP TY! The two bars (1) and (2) are made of the aluminum with E = 70 GPa, has the same cross section of 100 mm x 20 mm, and supported by rigid supports at A and C. The coefficient of thermal expansion of the material is 23 x 10–6/oC. At T = 25oC, the two bars have a gap of 5 mm as shown. a) What is the reaction force (in KN) at fixed support A when the temperature is 100oC? b) What is the reaction force (in KN) at fixed support C when the temperature is 100oC? c) What is the stress (in MPa) in bar (1) when the temperature is 100oC? d) What is the stress (in MPa) in bar (2) when the temperature is 100oC?
