Let $f(x) = \frac{2}{x - 4}$. Then according to the definition of derivative $f'(x) = \lim_{t \to x}$ (Your answer above and the next few answers below will involve the variables $t$ and $x$.) The expression inside the limit simplifies to a simple fraction with numerator = and denominator = We can cancel the factor appearing in the denominator against a similar factor appearing in the numerator leaving a simpler fraction with numerator = and denominator = Taking the limit of this fractional expression gives us $f'(x) = $

Two shafts, one of aluminum alloy and the other of steel, are coupled end to end. The steel shaft is 2 m long and is hollow with an external diameter of 100 mm and an internal diameter of 50 mm. The aluminum shaft is solid with a 100 mm diameter throughout its length of 1 m. The compound shaft is fixed at ends and a torque of 15 kN-m is applied to the coupling. Neglecting the effect of coupling, find: (a) Maximum shear stresses in the two portions of the shaft. (b) Angle of twist at the coupling. Take CSteel = 80 GN/m^2, and CAluminum = 25 GN/m^2.
