The T section shown in the Figure below is the cross-section of a beam formed by joining two rectangular pieces of wood together. The beam is subjected to a maximum shearing force of 60 kN. The NA is 34 mm from the top and that $I_{NA} = 10.57 \times 10^6 mm^4$. Using these values, determine the shearing stress (a) at the neutral axis and (b) at the junction between the two pieces of wood. Draw the shearing stress distribution. 200 mm 40 mm 34 20 mm 100 mm NA 334

The speed of a rotating drum of radius 260 mm can be controlled by the brake as shown. If the force P = 500 N is applied to the brake lever at point C, determine the time required to reduce the drum speed from $100\pi/3$ rad/s to rest. The mass of the drum is 300 kg, the drum's radius of gyration about its axis of rotation is 200 mm, and the kinetic coefficient of friction between the brake pad and the drum is 0.5. In the figure, $a = 160$ mm, $b = 800$ mm and $d = 100$ mm.
