1.Calculate the change in length of a 30m measuring tape made of steel when its temperature changes by 84 F. The coefficient of thermal expansion for steel is x = 3.1 x 10^-6 per C
2.Two pipes of identical length and material are connected in parallel. The diameter of one is twice the diameter of the other. What is the ratio of the flow rates (Q2/Q1) in the two pipes
3.Is it possible to predict the strength and deflection of an I-Steel beam and when you have your choice of choosing between an I-Steel beam or L-Steel beam which one will you prefer and why ?
