Figure Q4 shows the schematic for a pressure pad. The pad has area A and is connected to a rod of length 6L which is free to rotate about its hinge point at 0. The rod is supported by a damper of coefficient c and a spring with stiffness k, in the positions shown. The rod has a moment of inertia 1, about an axis through the pivot point, 0. The pad has a pressure P(t) applied to it which causes an angular displacement, 0, as indicated. Assuming small angular displacements, derive an expression for the transfer function of the system relating angular displacement 0 to an input pressure P. Derive an expression for the displacement of the rod, 0(t), in response to a step input of pressure of magnitude 100 Pa given the following data: 1, = 4 kgm²; c = 40 Ns/m; k= 500 N/m; L= 0.5 m; A= 0.2 m² Working from first principles, calculate the rise time, t,, of the system.
