An active camera stabilization system with a nonlinear torsional spring with the given characteristics is used to support the cantilevered mass (the camera). A controller will be implemented based on the model of the passive system. An initial twist is given by the actuator (the motor) to the spring so that static equilibrium (as shown). occurs with the rod horizontal Actuator 10(b +A R L 4 [in) KeQ(t) e(t) Camera i(t) schematic showing actuator and camera Figure 1.

How can you calculate the spring constant, K, of a mass-spring system given the amplitude is 13.5, the mass is 100 g, and the period is 8.1725?
5. A mass-spring system oscillates with an amplitude of 3.5 cm. If the spring constant is 250 N/m and the mass is 0.50 kg, a) Write an equation for the position, velocity, and acceleration for the mass as a function of time b) find the maximum speed of the mass, and the maximum acceleration of the mass. c) Sketch a plot of the position of the mass vs time by labelling the values for amplitude and period.
A circular hoop of mass 'm' and radius 'R' attached to a spring of spring constant 'k' at the centre of the hoop using a massless bar attached to the hoop,rolls without slipping on a horizontal surface. If the hoop is performing a periodic motion with a cyclic frequency ω, the value of ω is
(8 points) In physics, Hooke's law states that the length r of a uniform spring is a linear function of the force, y, applied to it. If we write y a +kx, then the coefficient k is called the spring constant. You are asked to determine the spring constant of a ]p spring has an unstretched measured length of 6.1 inches (i.e., r - 6.1 when y 0). You realize that because of experimental error, you want to take more...

PROBLEM 1 (35 %) The mechanical system in the figure below consists of a disk of radius r, a block of mass m, a spring of stiffness (spring constant) k, and a damper with damping ratio b. The disk has moment of inertia Jabout its center of mass (pivot point O), and the block is subjected to an external force t) as shown in the figure. The spring is unstressed when x 0= 0.
