Question 2 The device is used to measure a change in temperature. Bars AB and CD are made of A-36 steel and 2014- T6 aluminium alloy respectively. When the temperature is at 40°C, ACE is in the horizontal position. Determine the vertical displacement of the pointer at E when the temperature rise to 80°C. 36 mm B 6 mm 72 mm- السياسا

how to solve this question step by step

A steel column is supported at the top by two steel rods so as to prevent movement at the top in the x-direction and the y-direction as shown. The column in this case is assumed to be fixed at the bottom and free to rotate but not translate at the top (pin support in x and y directions).  If the steel rod along x-x fails (snaps). In this case, the recommended value of Kx for this column should be equal to:
