I apologize, but I'm unable to view or access any images. However, I can still help you understand how to write simultaneous Laplace-transformed differential equations for a rotational mechanical network.

In general, to write the Laplace-transformed differential equations for a rotational mechanical network, you need to consider the components involved in the system such as masses, springs, dampers, and external forces/torques. Each component will have its own transfer function, which represents the relationship between the input and output variables in the Laplace domain.

Here is a general procedure to follow:

1. Identify the variables involved in the system and assign them appropriate symbols. For example, let's say we have two masses, M1 and M2, with corresponding angles θ1 and θ2.

2. Determine the transfer functions for each component in the system. For example, the transfer function for a rotational inertia is s^2 (where s is the Laplace variable), the transfer function for a viscous damper is b (constant), and the transfer function for a torsional spring is k (constant).

3. Write the differential equations for each component using the transfer functions. For example, the rotational inertia component would have the differential equation M1 * d^2θ1/dt^2 = k * (θ2 - θ1) - b * (dθ1/dt).

4. Apply the Laplace transform to each differential equation to convert them into algebraic equations. For example, applying the Laplace transform to the equation from step 3 would give M1 * s^2 * Θ1(s) = k * (Θ2(s) - Θ1(s)) - b * s * Θ1(s), where Θ1(s) is the Laplace transform of θ1.

5. Combine the algebraic equations to form simultaneous equations. In a rotational mechanical network, the components are interconnected, so the equations for each component will be interlinked. For example, if there is a torque input T(s) acting on one of the masses, the equation for that component would involve T(s).

6. Solve the simultaneous equations to find the Laplace-transformed variables. Manipulate the equations to isolate the desired variables and solve for them. This will give you the Laplace-transformed representation of the system.

Remember to consider the initial conditions when solving the equations. Since you mentioned that all initial conditions are zero, you can set the initial values of the variables to zero when solving the equations.

I hope this explanation helps you understand how to write simultaneous Laplace-transformed differential equations for a rotational mechanical network. If you have any specific details or equations from Figure 1.15 that you would like me to help with, please provide them, and I'll be happy to assist you further.
