Chemical and Phase Equilibrium

Phase diagrams or equilibrium phase diagrams are the graphical representations that show the phase transformations of the constituting elements with respect to the pressure, temperature, and compositions. The diagrams show the conditions that limit the different phases, namely solid, liquid, and gas. The diagram can also be utilized to verify the relations between the state variables. Most of the phase diagrams are temperature-pressure phase diagrams, with the variable parameter as the composition. Usually other variables such as solubility and pressure parameters are not indicated in the phase diagram. For a one-component system (unary phase diagram), the phase diagram is generally a function of temperature and pressure as the state variables, or temperature and volume. However, for a binary system (two-phase) having two components, the phase diagram is a function of temperature and composition as the state variables only. Coexisting of the different phases of the constituting elements is indicated in the phase diagram. A ternary phase diagram can be characterized by consisting of three phases in equilibrium.

Question

please help me.

In the past, a rickshaw pulley design would only consist of pulleys A and D, as shown in figure
2. See figure 1 for the new pulley design, which includes additional pulleys B and C and the new
pulley system consist of pulleys A, B, C, and D. With this recent redesign, the power of a
rickshaw is now transmitted using the belt-and-pulley arrangement illustrated in figure 1. The
axle of the rea wheels is connected to pulley C instead of Pulley D as it was in the old Design.
A) Given that the rickshaw driver paddles pulley A at wA = (20t + 40) rad/s, where t is in
seconds, determine the angular speeds of pulley B and pulley C when t = 3 s.
B) Since electrical rickshaws are not allowed in some cities, does this new pulley design
significantly make it easier for the driver to pull passengers compared to the old design.
