Question

a) The steel rod shown in Figure 2 has a diameter of 12mm. It is fixed to the wall at A. and before it is loaded, there is a gap of 0.3mm between the wall at B and the rod. If the rod is subjected to an axial force of P =18kN as shown. Neglect the size of the collar at C. Determine the reactions at A and B.

 

b) Then, this rod heated and increasing 60°C from its initial temperature. Determine the normal stress induced in CB. Given that the modulus of elasticity and coefficient of thermal expansion for steel are Est=200GPa; αst= 10.8 x 10-6/°C
