AP4.2 The shoulder joint of a robotic arm uses a DC motor with armature control and a set of gears on the output shaft. The model of the system is shown in Figure AP4.2 with a disturbance torque $T_d(s)$ which represents the effect of the load. Determine the steady-state error when the desired angle input is a step so that $\theta_d(s) = A/s$, $G_c(s) = K$, and the dis- turbance input is zero. When $\theta_d(s) = 0$ and the load effect is $T_d(s) = M/s$, determine the steady-state error when (a) $G_c(s) = K$ and (b) $G_c(s) = K/s.$

In Example 13 from Cutnell and Johnson, suppose you used steel cubes instead of ice cubes to cool the lemonade. If the mass of the steel cubes is the same as that of the ice (i.e., 0.11 kg), what is the initial temperature of the steel cubes required to cool the lemonade to the same final temperature (i.e., from 27 $^\circ$C to 0 $^\circ$C)?
