The aluminum tube AB of cross section has a fixed support on the base and is supported by a pin at the top of a horizontal beam supporting a load Q = 200 kN. Determine the required thickness t of the tube if its outside diameter for 100 mm and the necessary safety factor in relation to Euler buckling for n = 3.0 (assuming A = 72 GPa).
I know the answer, but I cannot understand the critical charge formula. I don't know why to use the constant 2.046 in the formula, can you please show me?
2. Thermistors measure temperature, have a nonlinear output and are valued for a limited
range. So when a thermistor is manufactured, the manufacturer supplies a resistance vs.
temperature curve. An accurate representation of the curve is generally given by
1
= = a, + a, In(R)+a,{ln(R)}² + a; {In(R)}
T
where T is temperature in Kelvin, R is resistance in ohms, and a,,q,a,,a; are constants of
the calibration curve.

The 2014 T6 aluminum housing has the following properties: E =10.5 Mpsi, Sy =54 ksi, and the coefficient of thermal expansion (alpha) =23.1 x 10-6 K^(-1). The operating temperatures range from -30F to 400F. Which of the following statements are true? (Note: more than one statement could be true) There is a mismatch between the coefficients of thermal expansion between the steel and aluminum, which could lead to problems in the press fit at cold and high temperatures. The yield strength of the aluminum is less than that of steel, which means the aluminum will behave in a more rigid manner than the steel. The elastic modulus of steel is greater than that of aluminum, meaning that the aluminum will behave in a brittle manner while the steel will…arrow_forward
